Evaluation of Mechanical Properties of Cement and Zeolite-Stabilized Sand using Monotonic Simple Shear Test

Using a simple shear test, it is possible to investigate the behavior and recognition of soil resistive parameters. Cementation is one of the subsets of soil remediation that falls into the category of physical and chemical remediation that binds soil particles together and prevents the breakdown of the soil skeleton and increases shear strength (Consoli, 2009; Finn, 2002). The behavior of soil resistance parameters is investigated using simple shear tests. Shear stresses in the soil can be divided into static and dynamic (Li et al, 2016). One of the best ways to reduce cement consumption and production is to use pozzolanic materials, especially natural pozzolans, and replace them with cement. Pozzolans are widely used in the cement and concrete industry (Rahgozar et al, 2018). Micro-silica, perlite, methakaolin and zeolite are the most well-known natural pozzolans. Since the cost of producing pozzolans other than zeolite is almost high, their use would not be economical on a large scale. Zeolite mainly contains silica, and aluminum oxide, which reacts with calcium oxide and thereby increases the strength of the resulting compound. The addition of zeolite improves the spatial structure properties of the zeolite, as well as reduces the porosity of the resulting mixture (El Mir and Nehme, 2017). This paper presents the results of laboratory investigations on the shear strength of cemented sand and the effect of zeolite replacement on cement. To achieve this purpose, mineral zeolite, Shahroud cement, and Babolsar sand were used.
