Condense and harden fastly. freezing resistance. Applicable for project require fast condense, high initial strength and freeze-thaw cycle.
其凝结硬化快、耐冻性好，更适用于要求凝结快、早期强度高及受循环冻融的工程。

Frost resistance, give 100 times the natural freeze-thaw cycle, not mixed specimens peeling, SuSong strength loss as high as 70 %, Mixed specimens are intact, the surface strength loss 8 %.
In this paper the deterioration mechanism by freeze-thaw cycling, the test methods about frost resistance, appraising parameters of concrete and the influencing factors mainly were represented.
