description 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 kaolin clay.

The study's overarching aim is to optimize the geopolymerization process for both SBC-based and calcium silicate-SBC based geopolymers. Depending on the design parameters, geopolymer can be produced with various properties and advantages, such as excellent strength and thermal resistance under acidic environment.
