Abstract
Cement plays a crucial role as a binder in concrete production. With the evolving population, there is tremendous development happening all over the world in terms of infrastructure which is mostly of concrete. With this development, there is also a greater dependency on the cement. As known cement production contributes to the emission of greenhouse gases which cause harm to the environment. To overcome this problem to some extent, supplementary cementitious materials play a greater role. Materials that are mostly used as partial replacements for cement are the by-products of various industries such as fly ash, GGBS, spent pot lining, etc. There is also another material called Bentonite clay which can be used as a supplementary cementitious material as a partial replacement to cement. However, the study is limited owing to its properties such as its swelling nature etc. So, this paper reviews the feasibility of the utilization of bentonite clay as one of the materials as a partial replacement for cement in the production of concrete. This paper mainly reviews the mechanical properties and durability performance of bentonite-modified cement composites. It has been observed from the studies carried out that there is an enhancement in the mechanical properties and durability performance with the utilization of Calcined bentonite clay as a partial replacement for cement. The optimum dosage of the utilization of the bentonite clay was found to be in the range between 20-30 % by weight of the cement content.
