Research on Solid Wastes of Gangue, Slag, Fly Ash Used as Cement Composite Mixing Materials

Abstract:

The purpose of this study is to bring the fly ash, coal gangue and slag industrial solid wastes which contain the chemical composition for activation treatment, used as activated composite cement mixing materials, through strength test shows that the compound mixing materials impermeability activation treatment can obviously increase the cement strength. X-ray diffraction analysis (XRD), scanning electron microscopy (SEM) analysis results showed that the crystal structure of the mixed material calcined before and after have apparent change. There are lesss hydration products with compact structure of cement hydration 3d. The early strength of aiding composite mixing materials cement improved greatly.
