Nowadays, concrete has received special attention due to reasons such as the ease of preparation of constituent components, low costs compared to other materials, favorable engineering properties, extraordinary durability, formability, and most importantly, positive interaction with the environment. Although the construction of concrete with the main components of cement, aggregate and water is very simple and conventional, but the addition of new materials such as fibers causes the fragility of concrete to be significantly reduced and it shows ductile behavior under different loads. Fibrous concrete is actually a type of composite that, with the use of reinforcing fibers in the concrete mixture, does not easily fall apart under the impact of impact loads, and its tensile strength increases above normal.Concrete gains very little strength at very low temperatures, so when the degree of saturation of the concrete is not sufficiently reduced by the dewatering action, it is necessary to protect the concrete against damage caused by freezing. The use of polyolefin fibers and the effect of appropriate granulation in the concrete mixing plan is one of the effective factors in reducing the effect of freezing. In this article, the reason for the use of polyolefin fibers, the manufacturing method, mechanical properties, fiber concrete applications, and the effect of mixing design granulation on the compressive strength and abrasion percentage of fiber concrete samples in the normal environment and freezing, according to the results of applications and researches has been discussed.

One of the conventional recycling methods of asphalt mixture is the reuse of reclaimed asphalt with cement as a method for treatment of the base layer and its replacement in pavement layers. In this research, cold recycled asphalt mixture with using emulsified asphalt binder has been investigated through response surface method. In this regard, the technical and economical aspects of fabricated samples of recycled cold asphalt mixtures using crushed asphalt materials, cationic emulsified binder and Portland cement (type II) were investigated. Marshal strength and flow, bulk specific gravity and air voids of mixture were determined by experiments. By performing analysis of variance on the proposed models and determining the effective parameters, mathematical equations between independent and dependent parameters were developed and the effect of the parameters was investigated. Finally, an optimum mix design, which has 60% desirability, was suggested for cold recycled asphalt. Results showed that emulsified binder and cement content have significant effect on the marshal strength. Also, water exhibit a significant effect on the flow of asphalt mixtures.

In this study, the effects of sodium hydroxide solution concentration and sodium hydroxide to sodium silicate weight ratio on compressive strength, tensile strength, and elastic modulus of slag-based geopolymer concrete are investigated. The results of the experiments show that by reducing the ratio of sodium hydroxide to sodium silicate and increasing the concentration of sodium hydroxide, the compressive strength and tensile strength of concrete increase. In addition, by increasing the concentration of sodium hydroxide and reducing the ratio of sodium hydroxide to sodium silicate, the modulus of elasticity decreases, and no clear relationship is observed between compressive strength and modulus of elasticity of geopolymer concrete. Therefore, a mix design with a ratio of sodium hydroxide to sodium silicate equal to 0.4 and a concentration of 6 molarity sodium hydroxide with the highest compressive strength was selected to be used for the second step of the research. The performance of beam-column joints in past earthquakes shows their importance on the performance of concrete moment-resisting frames. Therefore, in the second step of this research, an experimental study is done for two beam-column joints with geopolymer concrete and ordinary concrete. In order to investigate the cyclic behavior of the joint, the experiment is performed according to the loading protocol of ACI 374.1-05. The results of the experiment show that the geopolymer concrete beam-column joint has the acceptance criteria of ACI 374.1-05 regulations, and also, its seismic performance assures that plastic hinge is generated in the beam properly.

In previous studies, the effect of different types of polyethylene on the performance of asphalt mixtures has been investigated. In this research, the mixing design of asphalt mixtures containing high density polyethylene has been analyzed and modeled based on the conventional and the response surface methods for limestone and granite aggregates. For this purpose, the volumetric and strength behavior of laboratory-made samples have been measured and statistically analyzed. In the optimization process,, the optimal amount of binder and polyethylene has been extracted according to the criteria of the asphalt pavement regulations for Iranian roads and with the desirability approach. Experimental results show that the optimal conditions for limestone aggregate are 6.1% binder and 4% polyethylene with a desirability of 0.909. However, these values for granite aggregate are 5.9% binder, 4% polyethylene with a desirability of 0.962. The polyethylene additive increases the Marshall strength and specific weight of the samples for both materials. The higher percentage of additive has the greater effect on these parameters. Analysis of variance shows that polyethylene percentage has a significant effect on Marshall flow. By increasing the amount of additive from zero to four percent, the flow value decreases.

Improving the mechanical properties of concrete with the help of fibers is considered as one of the common methods of concrete processing. Addition of fibers to concrete increases the energy absorption and ductility of concrete and prevents the spread of cracks. Steel, polypropylene and glass fibers are the most widely used fibers. In addition, new types of macro-synthetic fibers have been introduced. In this research, in order to improve the mechanical properties of concrete, a new type of macro-synthetic fibers has been used. Samples reinforced with 2, 4, 6 and 8% of fibers were evaluated using various compressive, flexural, tensile tests as well as elastic coefficient determination tests and their optimal consumption was selected. In this research, it has been tried that the test conditions are as compatible as possible with the industry conditions so that the final results of the research are in good agreement with the current situation of the concrete industry and can be used. Comparison of test results showed that, as expected, fiber-reinforced concretes have higher compressive, flexural, tensile strength and tensile strength than conventional concretes. In addition, between different percentages of fibers in concrete, in samples with percentages greater than 2%, the rate of increase of different strengths is lower than in the case without fibers. Therefore, considering the cost of macro synthetic fibers, the most suitable percentage for reinforcing concrete with them was introduced as 2%.

The purpose of this study is to investigate strategies to improve the skid resistance of roller-compacted concrete. Since the main weakness of roller-compacted concrete is the lack of pavement macrotexture, in this study, three types of macro textures, 1- Seeding (in three aggregate sizes), stamping (in two sizes), and grooving (one-way and two-way) were considered. In this research, eight mixing designs were selected to make roller-compacted concrete samples. The skid resistance of treated samples for 28 days before and after abrasion was evaluated by a British pendulum test. The results showed that concrete surface abrasion reduces the skid resistance of concrete samples by about 10%. The results also showed that changing different mixing designs did not have a significant effect on skid resistance. While the skid resistance is completely dependent on the type of macrotexture so that the grooved macrotexture shows the highest and the seeding shows the lowest skid resistance before and after abrasion.

The necessity of attention to the sustainable development in civil engineering for the progress of modern societies has highlighted concrete as the most widely used construction material for researchers. In this way, Ultra High Performance Concrete (UHPC) has been highly appreciated as one of the newest inventions in the field of concrete technology. The purpose of this article is to: 1- depict outstanding properties of UHPC that make its utilization in construction, rehabilitation and strengthening projects efficient and 2- promote the application of UHPC in bridge engineering in the national scale relying on extensive domestic studies in order to localize it. Much effort has been made to present a comprehensive report on innovations and gained experiences in the field of using UHPC in the bridge industry during the last two decades in all parts of the world and investigate the main direction of future research pointing to the key constraints of the widespread use of this material for constructing and maintaining bridges.

The idea of using paper wastes in concrete to reduce environmental pollution and Silica fume to improve the properties of concrete is a huge transformation in the building industry. In this study, the effect of waste paper ash along with silica fume on mechanical properties of concrete was investigated experimentally. The cement was replaced with different percentages of paper waste ash (0, 2.5, 5, 7.5, and 10%) and Silica fume (0, 2.5, 5, 7.5, and 10%). Then, 25 mix designs were prepared. Compressive strength, indirect tensile strength, flexural tensile strength, slump, ultrasonic pulse velocity, and impact tests are performed for all concrete specimens at different ages. Also, creep was presented for concrete-containing waste paper ash and silica fume based on existing equations and they were compared with the concrete code of USA and concrete code of Iran. These equations were suggested to predict the behavior of concrete-containing waste paper ash and silica fume. It was also observed that at a constant water cement ratio and for all ages, Silica fume and paper waste ash increased. Also, based on the results of this study, empirical relationships were presented for the relationship among indirect tensile strength and 28-days compressive strength of concrete, tensile strength due to flexural and 28-day compressive strength of concrete specimens, compressive strength and specific weight. Thus, these equations could be used to predict the behavior of concrete-containing paper waste ash and Silica fume. The tensile strength/compressive strength ratio of ordinary concrete was about 10. However, this ratio was between 13.55 and 17.79 in concrete specimens containing waste paper ash and silica fume. The compressive strength ratio of 28 days to 90 days was between 0.67 and 0.81. However, this ratio was between 0.55 and 0.65 in ordinary concrete, which indicates the higher initial strength of specimens containing waste paper ash and silica fume.

One of the useful and efficient ideas in pavement and flooring is use of permeable concrete which is called pervious concrete. Pervious concrete that has many economic and especially environmental impacts can be used for reducing surface runoff during rainfall, delaying the entry of rainwater into the sewage system due to its absorption by the ground, improving the quality of groundwater due to lack of water flow from the ground and contact with possible contamination. In this study, four different mix design were used for three types of aggregating aggregates, which contains 12 general mixing states, including samples of simple concrete and examples of microsilica fume additives. At the end, compressive strength and permeability tests have been carried out on them. The results obtained from the research show that the individual with a higher density or, in other words, a finer grain size, exhibited a compressive strength of 9 Mpa, but had a 15% lower permeability. In general, according to the results of these experiments, the factors affecting the density of pervious concrete can be expressed by the size of the aggregates, the efficiency and the amount of microsilica fume. Because of its superplasticizering, the microsilica fume increases the strength and durability of concrete but reduces porosity of concrete, but its permeability is still acceptable to simple concrete. Finally, the optimum aggregate for compressive strength and optimal permeability, is obtained in third type of aggregating in this study, In which half of the aggregates have been formed of residues on the sieve of 3.8 and the remaining half of the residues on the sieve of 4 and depending on the need for greater resistance or permeability, parameters such as water to cement ratio, sand/cement ratio and microsilica fume addition can be obtained, which has been investigated in this study.

In this research, rocks were selected from different mines to evaluate the engineering properties of In this research, rocks were selected from different mines to evaluate the engineering properties of aggregates in concrete and then used for making concrete. At first, the physical and mechanical properties of the selected aggregates are determined in the laboratory, and then the aggregates are subdivided into sand-sized aggregates and some aggregate properties such as shape, porosity, impact value, compressive value and aggregation are determined. Then, using a fixed mixing scheme, the aggregates were prepared from concrete and the mechanical properties of the prepared concrete such as compressive strength, tensile strength and elastic modulus were determined after 7, 28 and 90 days. the effect of each of the aggregate properties on the concrete strength is investigated. This percentage is a useful guide for identifying the desired aggregates as well as the tests required to explore the aggregate resources. The results show that the resistance properties, abrasion, specific gravity and porosity, shape and texture, durability and stability of aggregates have the most effect on concrete strength, respectively.

Many factors or parameters influence the field density of asphalt mixes. Since the number of variables affecting a large and somewhat different compacts affects each other, it is almost impossible to determine a constant interpolation relationship. Data mining and its techniques are a way of discovering hidden knowledge between dependent and independent variables, as well as indirect and nonlinear relationships can be identified by dividing the data into groups or leaves in the decision tree method. In this study, commonly used data mining techniques in civil engineering, including the neural network, logistic regression and decision tree. By emphasizing the application of decision tree method, with the aim of exploring knowledge models and providing predictions, other data mining tools are used to assist in constructing and evaluating the developed satistical model. The explanatory variables used in the three models of this study are the percentage of void, asphalt mix strength, aggregate size, bitumen percentage, asphalt mix flow. The results show that the percentage of void content of stone materials, the percentage of passage of sieve 200 and 4, and the bitumen percentage had a greater effect on the density and compaction of asphalt mixture. Also, a multiple linear regression model with a correlation coefficient of nearly one between the density of asphalt mixture and variables were presented.

Concrete as the most consuming material Construction has long been a response to the growing needs of the human community, whose parameters are constantly changing. Scientists' research over the past two decades has led to the emergence of a new type of concrete with high properties and high compressive strength, which is known as concrete with ultra high performance. The main goal of the present study is to achieve a mixing design with a compressive strength suitable for ultra high performance concrete, without the use of fibers. First, the basic mixing plan has been considered, and with the change in the type and size of materials and also by applying different curing, the compressive strength of the samples has reached 212 MPa. To create ductility and absorption of energy in concrete made with mixing design The present research has used polyvinyl alcohol fibers, polypropylene fibers and steel fibers as a single and hybrid for the reinforcement of concrete. Maximum usable fibers, ductility, and compressive strength that make the fibers mentioned Single and hybrid for this concrete are determined and compared with each other. The results of this experimental study showed that samples containing 2% fiber had the best mechanical performance, as well as samples of 1.5% polypropylene fibers and 0.5% polyvinyl alcohol fibers The most ductility for concrete has been created.

Global water scarcity and air pollution by greenhouse gases have amplified the need to use of unconventional water and environmental friendly materials in the concrete industry. Because of its proximity to the Caspian sea, the geological conditions and hydrogeological characteristics of the northern and western regions of Golestan province, groundwater in this area is very salty. On the other hand, due to lack of access to good quality surface water in most of the months, civil and construction activities in this area are always challenging. Accordingly, the present study was conducted to investigate 120 treatments (including three levels of water quality including tap water, briny grounwater and  mixture of equal ratio of tap water and briny grounwater), four levels of zeolite (including 0, 10, 20 and 30 percent of zeolite application instead of cement in the concrete mix design), two levels of cement content (including 250 and 350 kg.m-3) and five curing ages (including 3, 7, 21, 56 and 90 days) in three replications. Considering the considerable types of the experimental treatments in this study and in respect to the lack of statistical analysis in previous studies, the results of this study were analyzed based on a completely randomized design with factorial experiment using analysis of variance (ANOVA) and means comparison (LSD) tests. Averagely, use of briny groundwater resulted insignificant increase in the compressive strength of concrete specimens compared to tap water, while combined water significantly decreased this property, but this reduction was within permissible range 10 percent based on national and international standards. Also, replacement of 10, 20 and 30 percent of cement by zeolite compared to non-zeolite treatment significantly reduced the compressive strength of concrete specimens by 9.9, 9.5 and 23.1 percent, respectively, but the difference between replacement level 10 and 20 percent was not significant. However, Concurrent use of briny groundwater and zeolite up to 20% can be recommended without significantly reducing the compressive strength of concrete. In the cement content of 250 kg.m3, the difference between tap water and combined water treatments was not significant, but the use of briny groundwater resulted significance increase in compressive strength of concrete pieces by 22.8 and 21.8 percent compared to tap water and combined water, respectively. In contrast, in the cement content of 350 kg.m-3, the highest compressive strength was obtained in samples made with tap water, briny groundwater and combined water, respectively, and the differences between them were statistically significant. The results showed that due to double and triple interaction of these three factors on compressive strength of cement pieces, which means different effects of water quality and application percent of zeolite on different content of cement, the choice of the best application level of zeolite and water type according to the cement content should be selected based on the mix design test in building site. However, using of briny grounwater and zeolite in the concrete mix design, especially in cement content of 350 kg.m-3, without significantly reducing the compressive strength of concrete and even significantly increase of this property in some treatments, is recommended.

Global water scarcity and air pollution by greenhouse gases have amplified the need to use of unconventional water and environmental friendly materials in the concrete industry. Accordingly, the present study was conducted to investigate interaction of water quality, zeolite, cement content and curing age on concrete compressive strength. Regarding to the considerable types of the experimental treatments in this research and with respect to the lack of statistical analysis in previous studies, the concrete compressive strength data of this study were statistically analyzed by ANOVA and LSD tests based on a completely randomized design with factorial experiment with three replications. The results of analysis of variance test showed that the simple effect of the investigated factors, their two-way interactions, except water type*curing age and zeolite*curing age, and the three-way interaction of cement content*water type*zeolite on compressive strength of the concrete specimens were statistically significant. Due to the lack of significant negative effect of treated industrial wastewater and the mixture of equal tap water and treated industrial wastewater on the compressive strength of concrete, it is recommended to use these waters in the construction of plain concrete. However, the three-way interaction of water type with zeolite and cement content showed that the effect of investigated waters on compressive strength of concrete specimens in different percentage of zeolite is depended on cement content. So, the choice of the best application level of zeolite and water type according to the cement content should be selected based on the in- situ mix design test.

Pay factors are an integral part of the quality assurance. Since the production and supply of asphalt cannot meet all the specifications in accordance with the criteria, determining the relationship between quality and payment is important. The results of the studies on 21 Marshall mix design and 592 sheets of quality assurance and field inspections from asphalt plants show that in preparing the mixing design some cases of inaccuracy in determining the type of traffic, sampling, determining the optimum bitumen content and using The mixing plan is seen for a period of several years. In general, quality control has been low in the 12 projects examined, and there are no recommendations for general technical specifications. Marshall's experiments in this study that affect the pay factor are performed without hammer calibration and are sometimes computable mistakes. It was also found that in some of these projects, in spite of the lower percentage of Marshall parameters inside the specification, they had a higher pay factor, which could be considered And considering the reasons for the non-conformance in this research, it can determine the ineffectiveness of the selected pay factor or indicate that the use of (QA) results for acceptance and payment to the contractor, regardless of quality control (QC) Cannot be used as a way to increase the quality of asphalt pavements and to include costs based on the life cycle.

The procedures for measuring, mixing, transporting, and placing heavyweight concrete are similar to those used in conventional concrete construction; however, special expertise and thorough planning are necessary for the successful completion of this type of concrete .The use of heavyweight concrete in construction is a specialized field, Heavyweight concrete is used in counterweights of bascule and lift bridges, but it is generally used in radiation shielding structures to absorb gamma rays and differs from normal weight concrete by having a higher density and special compositions to improve its attenuation properties. When heavyweight shielding concrete is used to attenuate neutrons, sufficient material of light atomic weight, which produces hydrogen, should be included in the concrete mixture. Some aggregates are used because of their ability to retain water of crystallization at elevated temperatures, which ensures a source of hydrogen not necessarily available in heavyweight aggregate Cements would be suitable for conventional concrete and produce the required physical properties, are suitable for use in heavyweight concrete. Low-alkali cement should be used when alkali-reactive constituents are present in the aggregates and a moderate or low-heat cement should be used for massive members, To avoid high and rapid heat of hydration and resultant cracking, it is advisable not to use Type III cement or accelerators unless the concrete temperature is controlled by specially designed refrigeration systems. Thorough examination and evaluation of heavyweight aggregate sources are necessary to obtain material suitable for the type of shielding required. These sources are limited, and a material survey should be conducted to determine availability, chemical and physical qualities. The supplier’s sources should be inspected to evaluate rock composition, abrasion resistance, and density since these properties may vary from one location to another within a deposit. The purchaser must realize that mineral ores are not as uniform as normal weight concrete aggregates and make appropriate allowances Limited resources and increasing use of concrete, particularly in the industrial production cause that the heavyconcrete be useful. In order to optimize production of heavyconcrete, the most basic parameters that must be changed is the mix design. Optimization of the concrete mixture design is a process of search for a mixture for which the sum of the costs of the ingredients is lowest, yet satisfying the required performance of concrete, such as workability strength and durability. For this purpose, heavy concrete mix design optimization model is firstly defined and then optimal mix design will be achieved, by using an optimization algorithm. The experimental data were utilized to carry out analysis of variance. To develop a polynomial regression model for compressive strength in terms of the five design factors ( cement, coarse aggregate, fine aggregate, water and density ) considered in this study The numerical results shows that the amounts of coarse aggregate and cement are simultaneously reduced and amount of the fine aggregate is increased in the optimum mix design. Considering mass production concrete in nuclear power plants, this optimal mix design methods and reduce the cost of concrete can greatly reduce the cost of construction

self-compacting concrete is one of the most widely used concrete in the past two decades. The objective of present study is to introduce a new method for high strength self-compacting concrete mix design to both achieving maximum compressive strength and minimizing the cost of concrete. The proposed method is an analytical method. In this method, using optimization concepts such as Lagrangian function and Kuhn–Tucker conditions, and introducing a specific relationship to the compressive strength of concrete, without the need for computer computations, and based on a completely analytical method, provides optimal concrete mix design. The proposed method is a general approach and is applicable to all types of concrete. Here, for the purpose of introducing, the method used to high strength self-compacting concrete containing fly ash. An optimization model of the concrete mix design is first developed accounting for effects of experimental results. Then, using an optimization algorithm, optimal concrete mix design is obtained for the concrete with the strength under consideration. Results showed that the proposed method can provide optimal mix design of high-strength self-compacting concrete while water and cement amount are the minimum amounts required for self-compacting concrete.

Nowadays, using in-situ cold recycling has grown substantially as an economical method to rehabilitate the eroded roads. Among these cold recycling methods, the use of foamed bitumen technology has been of much interest to engineers due to its ease and rapidity of implementation. In foamed-bitumen mixtures, in order to reduce the moisture sensitivity and increase the resistance properties, active fillers such as cement and lime are used. But, there is no proper and standard mixture design for these types of mixtures and performing mechanical trial and error experiments is time consuming and expensive. Thus, it seems necessary to find a simple method that has enough accuracy and could estimate the mechanical behavior of recycled foamed-bitumen samples. In this research, mixtures were made by adding foamed bitumen binder (1, 2 and 3 percent) to the recycled material and Portland cement (0, 1, 1.5 and 2 percent), and mechanical characterics of the samples was measured by Marshall stability tests, resilient modulus and indirect tensile strength (soaked and unsoaked). Then, with statistical analysis, a new mathematical formula for each test was presented with appropriate accuracy. The presented models can predict mechanical characteristics of the recycled foamed bitumen mixture on the basis of bitumen percentage and cement with enough accuracy and without spending time and money. Also, it was found that by increasing the bitumen content, the behavior of these mixtures in the performed tests was not similar. Such that increasing bitumen from 1% to 2%, Marshall resistance and resilient modulus increased and thenafter they decreased by increasing the bitumen percent. But, by increasing the bitumen content, indirect tensile strength (soaked and unsoaked) increases too. On the other side, addition of cement increases resistance and decreases moisture sensitivity of these mixtures.

Concrete is the most widely used building materials. In the our country, Iran, the consumption amount of chemical additives materials than to the average consumption in other countries has been a significant distance and especially ready-mixed concrete industry the significant contribution of concrete production and consumption to be allocated in the country. Ready-mixed concrete industry from the most potential sections that should be pay to the valuable characteristics of the chemical additives and used to it. Therefore it is essential that developed the knowledge and technology use of chemical additives materials over the past in Iran. One of the cases that about concrete structures, especially structures that located in the vicinity of water permanent or non-permanent and chemicals materials, is important, blocked effect performance against leakage, influence, pressure or attack water containing chemical materials, addition to it is well tolerance freight its. In this context, should be made concrete that commonly “waterproof” is called. Also, to prevent cracking, high ductility, supernatural strength and energy absorption capability can be used of fiber in concrete that can be found proportional many application instances for it. Up to now specified that different types of fiber can increase strain capacity, resistance to impact, energy absorption, abrasion resistance and tensile strength of concrete. In this research, the influence of the strength of concrete and fiber concrete sealing substances has been investigated. For this purpose, concrete without fibers and fiber concrete with steel fibers, polypropylene and glass, compressive and flexural strength parameters by adding common waterproof material is studied with different percentages. In this study, by using of materials available in the Khormoj and fiber and waterproof materials, concrete parameters is evaluated of pressure and bending resistive. Carrying out tests crash sand in the province of Bushehr was used. All the stone materials in the concrete mix thoroughly washed before using in the S.S.D state. Dashtestan Cement Type 2 Compliant with ASTM C 150 is used for mixing. Thus, was carried compressive strength tests at ages 7, 28 and 90 days on the cubic test pieces and bending strength tests at ages 7, 28 and 90 days on test pieces of the cubic rectangular. Tests taken in 34 mix design and 408 samples so that in the making concrete is used of waterproof materials composition of inclusive powder sbf-wr201 (acidic neutral) and powder bc40 (acidic neutral) and liquid bc39 (alkaline) and steel, polypropylene glass fiber. In this study, a mix design based on ACI 211 recommendations for concrete without fibers by weight method was prepared. Then fibers (polypropylene, steel and glass and 2% respectively, 2%, and 1% by weight of cement) and the waterproof material (with percentages of 1, 1.5, and 2% by weight of cement) were added separately to the concrete mix design and the mix design was calculated for each compound. The tests of results show that the waterproof materials bc40 and sbf increase the strength and flexural compressive and waterproof material bc39 decreases concrete strength and flexural compressive. The most important result of this study is that to add 1 percent of waterproof materials bc40 to the fiber concrete with steel fiber has been increased 27% compressive strength compared than to control sample fiber for strength 90-day and also in the flexural strength of this combination is not seen a significant change.

Recently, various researches have been undertaken on the high performance concrete (HPC). In order to obtain high strength concrete, certain materials and modern procedures are essential needs to get the result. Reactive powder concrete is a type of HPC that is under consideration of many recent works. The manufacture of HPC needs special materials that are not always accessible and applicable. However, in the present laboratory research regarding to the principles of reactive powder concrete manufacturing and using local available materials, it has been attempted to make HPC. In this view, numerous mix designs with different w/c and s/c proportions are made. The mix designs are added with and without standard amount of silica fume. Eventually, optimized and applicable mix design was obtained. According to reactive powder concrete manufacturing principles by using local materials, this type of concrete could be known as "modified reactive powder concrete".
