Experimental Research on the Properties of Modified MPC


Article Preview

Magnesium phosphate cement (MPC) was modified by fly ash, silica fume and re-dispersible latex powder and the properties of modified MPC, such as fluidity, setting time and compressive strength, were tested. Based on the experimental results, the contents of 50% fly ash, 10% silica fume and 2% re-dispersible latex powder were chosen to modify MPC and the water resistance of the modified MPC was studied. The experimental results showed that the addition of fly ash prolonged the setting time and significantly increased the compressive strength of MPC. The addition of silica fume improved only the water resistance of MPC. The addition of the re-dispersible latex powder prolonged the setting time and improved the water resistance of MPC.
