Geopolymer Concrete: An Alternative of Conventional Concrete

Abstract

The rising cement demand is a direct result of the widespread usage of cement concretein construction activities. Production of cement is causing greenhouse gas emission.This study investigated the compressive strength (28 days) of geopolymer concrete(GPC), a material that might one day replace cement concrete. Geopolymer concretecube specimens were prepared for evaluating compressive strength after 28 days. Effectof binder content and effect of curing is studied. Total 6 cubes were prepared for eachmix type. 3 cubes were provided ambient curing and 3 were provided temperaturecuring. Results showed that the compressive strength after 28 days was positivelycorrelated with the amount of GGBS used as a binding agent. It was also observed thatcompressive strength (28 days) of GPC specimen having temperature curing are higherthan ambient cured geopolymer concrete specimen
