“…The effect of bentonite clay on properties of grout is studied by another researcher [8]. Similarly, the performance of activated soil-cement-bentonite clay can be found at another source [9]. One of the studies investigated the use of natural bentonite clay for the recovery of Gd3+ from real leachate of phosphogypsum.…”

This research focuses on finding an alternative to expensive cement in the construction industry in Pakistan by utilizing pozzolanic materials, specifically volcanic ash/bentonite clay. By replacing a portion of the cement with bentonite (10%, 20%, 30%, and 40%), the study demonstrates the potential to reduce the net consumption and cost of cement while also contributing to more durable concrete and reducing energy consumption and greenhouse gas emissions. Physical properties such as setting time and fineness were studied, and the compressive, flexural, and split tensile strength of the mixes were compared at 7 and 28 days of curing. While the strength of the mixes decreased with the successive addition of bentonite, the rate of reduction was much lower at 28 days than at 7 days. The results validate the feasibility of developing low-cost concrete using bentonite as a partial replacement for cement.
