Waste glass powder and metakaolin were used to prepare geopolymer mortar.The effects of alkali activator with different sodium silicate modulus and liquid-solid ratios on the fluidity and mechanical properties of the waste glass powder-metakaolin geopolymer mortar were investigated,and the crystal structure,thermochemistry,pore structure,and micromorphology of the geopolymer mortar were analyzed by X-ray diffraction(XRD),Fourier transform infrared spectroscopy(FTIR),thermogravimetric-differential scanning thermal(TG-DSC),mercury in piezoelectricity(MIP),and scanning electron microscopy(SEM).Th...
