Abstract :
The adoption of volcanic ash active admixture and admixture can enhance the alkali degree in the magnesium oxychloride cement system, generate calcium-magnesia alley stone crystal, hydrated magnesium silicate and chloride aluminate, enhance the hydration phase stability, water resistance and post-phase strength of cement. The addition of sands can reduce the dosage of magnesium oxychloride cement and restrain the distortion of cement stone and improve the stability of magnesium oxychloride cement bulk.
