Abstract
The effect of the amorphous silica derived from biomass rice husk (RH) in the alkaline activating solution on the properties was investigated in geopolymerization process, when metakaolin was used as the aluminum source from metakaolin (MK). With changing a molar ratio of SiO 2 /Al 2 O 3 = 3.0 and 10, the curing in the preparation of geopolymers was carried out at 85 ° C, 100 ° C and 200 ° C. Viscoelastic properties of the geopolymer pastes including SiO 2 and Al 2 O 3 components suggested that the alkaline activation was found in higher RH silica source. The mineralogical and microstructural characteristics of the cured products were evaluated to be amorphous aluminosilicate.
