Presently, geopolymer blocks are being produced by using industrial by-products like fly ash. This study focuses on the development of geopolymer cement blocks using the composition of bentonite and fly ash. The specific objective is to examine and optimize the geopolymer cement block parameters using a novel composition. The oxide ratio, alkali activator ratio, and molarity are considered variables. In contrast, the responses are considered as flow table, fresh density, compressive strength, compressive strength – temperature curing, density and water absorption. The mix matrix design was generated upon fixing the lower and upper limits of variables using response surface methodology (RSM). The laboratory experiments were conducted as per the mix matrix design to obtain the responses. The RSM model was developed using the values of responses for all mixes; analysis was also performed to verify the significance. It was found that all terms in the model were significant, showing a confidence level of more than 85 per cent. Furthermore, multi-objective optimization was also performed for the specified variables with a desirability of 1.0. At the outset, the development of geopolymer cement blocks was confirmed.

Keywords: Geopolymer, bentonite, fly ash, oxide ratio, alkali activator, molarity, response surface methodology (RSM)
