The Effect of Alkali on Compressive of Metakaolin Based Geopolymeric Cement

Abstract:

In this study, Metakaolin was used as source material, NaOH and sodium silicate were used as alkali activators.Preparation of three sets of geopolymer samples subject different NaOH concentration from 8 to16mol/L. The effect of alkaline concentration on compressive strength was analyzed. NaOH concentrations at 12mol/L and 16mol/L resulted in high 7-day compressive strengths. And the compressive strength of geopolymeric cement reached the maximum when adding 24mL sodium silicate at SiO₂:Na₂O ratio 3.3.
