The Experimental Investigation on Geopolymer Concrete

This paper presents an experimental investigation on fly ash-based geopolymer concrete. Various mix compositions were tested using different percentages of metakaolin as a partial replacement for fly ash (0%, 5%, 10%). The study analyzed compressive strength, split tensile strength, flexural strength, and workability (slump). Results indicate that 5% metakaolin replacement provides optimal mechanical and workability properties. The study further suggests practical applications and future research possibilities in structural and sustainable construction.
