Investigation Of Physical And Chemical Properties Of Spent Bleaching Clay Based Geopolymers Using Alkaline Activated Geopolymerization Process

This research explores the synthesis and characterization of porous clay-based geopolymers using uncalcined spent bleaching clay (SBC) as a novel precursor. Geopolymers, celebrated for their mechanical strength and chemical durability, have traditionally been synthesized using fly ash or calcined ka...
