Research on the Strength Properties of the Magnesium Phosphate Cement (MPC) under the Sub-Zero Temperature Environment
In this paper, the strength characteristics of magnesium phosphate cement (MPC) under the sub-zero temperature environment had been researched, the main factors of the strength development had been analyzed. The results show that: the MPC has high early strength under the sub-zero temperature environment, but the compressive strength dropped as the temperature decreased. The way of pre-curing the MPC for 30min at 20 could improve the strength of the MPC significantly. The strength of the MPC is influenced greatly by water-cement ratio under the sub-zero temperature environment, and the amount of the mixing water should be controlled strictly.
