| Abstract: | In order to study the salt corrosion resistance of hardened slurry of magnesium ammonium phosphate cement with high fluidity. The compressive strength, flexural strength, deformation, water absorption, fluidity, hydration temperature curve and microstructure of MAPC cement with high fluidity were tested. The properties of MAPC hardened slurry of the blank group M0 and single mixing water glass M1 immersed in water, sodium chloride and sodium sulfate solutions for a long time were studied. The experimental results show that the early hydration reaction rate and fluidity of MAPC hardened slurry are improved by single mixing water glass. The strength, deformation and water absorption of MAPC hardened slurry are improved by single mixing water glass. In addition, no matter under any solution, the performance of M1 slurry sample of single mixing water glass is better than that of the blank group M0, and the performance is the best under sulfate solution. |
