Lightweight Concrete and its advantages compared with conventional concrete

Concrete is one of the most widely used materials in the world. Considering the need to build high-rise structures, especially in building industry, it is better to reduce the dead load of buildings, structures lighter and also reduce the stress of.One of the best solutions for this purpose is using lightweight aggregate concrete in addition to make structures has another benefit too.In this paper we show that lightweightconcreteespecially at elevated concrete structures can be a great alternative to Ordinary concrete. Lead only to reduce the dead load of the concrete structure does not havebut sound insulationand thermaland the ability to recycleand various other benefitsare the advantages of this type of concrete.The use of concrete in construction increase the cost of materials but overall, economic savings willbe greater in high-rise structures. The use of lightweight aggregate concrete not only in concrete but also has very efficient in building blocks. In this paper comparing the two types of concrete has been studied in two ways. First benefits of physical propertiesand second in terms of properties engineeringincluding compressive strengthtensile strength and modulus of elasticitybeen discussedand proven that the lightweight concrete has many advantages substitute for conventional concrete and old material
