Abstract

Abstract

The relation between contents of crystalline or amorphous phase and compressive strength were discussed to further understand the mechanisms of flyash matrix geopolymer. Firstly, a kind of high strength flyash matrix geopolymer was prepared based on parameter optimization for alkaline activators, and specimens of different strength cured in different temperatures and for ages were prepared. Then, the microstructure of the specimens was scanned with SEM; meanwhile, the mineral quantitative ingredients of the geopolymers were analyzed by XRD-Rietveld, and the contents of crystalline or amorphous phase in geopolymers were determined. Based on the XRD results, the correlations between contents of amorphous phase substracts and strength were analyzed. The results showed that the contents of amorphous phase substracts were in a positive correlation with the strength of geoploymers.
