摘 要：<正> This Paper is a study on the rule of the decline of properties of cement composite being damaged in the freezing thawing circle. By analyzing the damaging process of cement composite in such a circle,the author sets up a model of "vicious circle" and then deduces and proves the decline function of the properties of the cement composite. It is proved that the frost-resistance of cement composite depends on its internal hydraulic pressure. A fast testing method and a judging index Rf for the frost resistance of cement composite are also suggested.
