The process of making portland cement uses up a lot of resources and has a harmful environment effect since it produces a lot of greenhouse emissions. The by-product of the stone cutting and polishing industries is Bethamcharla waste Stone Powder (BWSP). Each industry produces an average of one tonne of waste each year, which is then simply deposited on the plains of Bethamcharla. In order to convince civil engineers to employ this new industrial waste material in Geopolymer Concrete (GPC), this research will examine the effects of substituting BWSP for Ground Granulated Blast-furnace Slag (GGBFS). Experimental investigations were conducted toward issues relating to strength. In the amounts of 20, 40 & 60 % by weight of GGBFS, the BWSP was employed as a substitute. Initial total mixes are prepared during the experimental inquiry with varying molarities of 8, 10, 12, 14, and 16 as well as changes to the mix proportions. According to the trials, the 16 molarity and 1:1.32:3.1 (GGBFS: FA: CA) mix with alkaline solution delivered preferable outcomes, allowing for the fullest possible use of BWSP in the mix. The current study provides information on the behaviour of BWSP in Geopolymer Concrete. As determined by the study, the minimum strength of concrete (M25) cannot be affected while using 60% BWSP with 16 molarity for construction.
