Effect of Water Glass on Compressive Strength of Aluminosilicate-Based Geopolymer

Abstract:

Article Preview

The inorganic binders, fly ash and meta kaolin were used to prepare geopolymer. Water glass was added to the recycled inorganic binders to improve compressive strength of geopolymers. The ratio of the solid materials (inorganic binder and alkali activators) and liquid materials (distilled water, water glass) for the polymerization was optimized as 3:1. Compressive strength of the geopolymers increased because water glass improved the extent of polymerization of the inorganic binder and resulted in dense microstructure. It was found that geopolymers using fly ash showed the higher value of compressive strength, compared with meta kaolin- based geopolymers.
