文摘

Fly ash was blended with additives to enable ambient curing of geopolymers. Geopolymer concretes (GPC) exhibited higher flexural strength than OPC concrete. Elastic modulus of GPC is 25–30% less than that of OPC concrete of same strength. An equation is proposed to predict the modulus of elasticity of ambient cured GPC.
