Abstract
Phase evolution and microstructure development of metakaolin-rice husk ash geopolymer have been investigated. The initial molar ratios of SiO2/Al2O3 were designed in the range of 2.0–7.0 with Na2O/Al2O3 ratios of 0.6–1.6, Na2O/SiO2 of 0.20–0.72 and H2O/Na2O of 10.0–20.0. The specimens were cured at 30 °C for 1–90 days prior to characterization of phase and microstructure as well as mechanical properties. The designed molar ratios were found to...
