sodium bentonite and calcium bentonite by attributes [9-11]. According to the study of many scholars, the use of sodium bentonite instead of cement is much better than calcium bentonite. The bentonite in China is very rich and it is more available than other pozzolans. Bentonite will help reduce greenhouse gas emissions and it will have a
Bentonite. The most frequently used clay-based cement extenders is bentonite, also known as "gel,". Bentonite has the unusual property of expanding to several times its original volume when placed in water, resulting in higher fluid viscosity, gel strength, and solids-suspending ability. Bentonite is added in concentrations up to 20% BWOC.
Abstract. Replacing cement with pozzolanic materials to some extent in construction is found to be one of the sustainable approaches in the construction industry.
