Abstract

This paper presents the effect of Alkali activator / Fly ash ratio (A/F) on strength and workability of geopolymer concrete prepared from low lime based fly ash and a mixed alkali activator of sodium hydroxide and sodium silicate solution. The workability of concrete is found to be increasing when the A/F ratio is increased. An increase in compressive strength of the concrete samples is observed when the A/F ratio is increased for the samples cured at 60oc.
