The syntheses of lightweight geopolymeric materials from highly porous siliceous materials viz. diatomaceous earth (DE) and rice husk ash (RHA) with high starting SiO2/Al2O3ratios of 13.0-33.5 and Na2O/Al2O3ratios of 0.66-3.0 were studied. The effects of fineness and calcination temperature of DE, c...
