Performance of Metakaolin and GGBS-induced Geopolymer Concrete Under Compression

Jabeen Khan, Sanjay Kulkarni

Abstract


Metakaolin and ground granulated blast furnace slag (GGBS) were used as the source materials to obtain the high strength geopolymer concrete. NaOH and sodium silicate were used as alkaline activators with varying NaOH molarities of 8M, 12M, 14M and 16M. Cubes of size (100x100x100) mm were cast and the four geopolymer mixes were heat cured for varying durations of 24 hours, 48 hours and 72 hours and tested for compressive strength at 7 days of casting. It was found that as the molarity of NaOH increases, the compressive strength also increases, but beyond 14M change in compressive strength is minimal. Also as the duration of curing temperature increases, the compressive strength also increases.
