Geopolymer Microstructure and Hydration Mechanism of Alkali-activated Fly Ash-based Geopolymer

摘要：

The microstructure and hydration mechanism of alkaliactivated fly ash-based geopolymer were studied by means of scanning electron microscope (SEM) coupled with energy dispersive X-ray analysis (EDXA) and field emission scanning electron microscope (FESEM). The FESEM photomicrographs indicted that the fly ashbased geopolymer showed three dimensional frameworks with an average particle size of 50 run. EDXA results demonstrated that the Na-PSS type geopolymer was produced via the disintegration of Si-O-Al and Si-OSi chemical bonds and the polycondensation reaction
