Abstract

Abstract

The drying shrinkage of magnesium phosphate cement mortar was studied in the paper，including the influence of reactivity of magnesia，water to binder ratio，magnesium to phosphorus ratio，fly ash content and usage of retarder on the drying shrinkage of magnesium phosphate cement mortar. The conclusions indicated that the drying shrinkage of magnesium phosphate cement mortar increased with the decreasing of the magnesia reactivity，magnesium to phosphorus ratio and fly ash content，increasing of the water to binder ratio and usage of retarder. And the analysis showed that the evaporation of free water is the main reason for drying shrinkage and fly ash content could restrain the drying shrinkage of magnesium phosphate cement mortar.
