| 摘 要： | This paper investigates the frost-resistance function and the improvingmechanism of frost-resistance of variouspolymer cement concrete (PCC)' containingtwo kinds of different polymer emulsions.The test results shows that the declinerule of the frozen-thawed PCC follows thefrost-resistance function obtained before.It is considered that the frost-resistanceof cement composite not only dependes onthe strength of internal hydraulicpressure,but also dependes on the abilityresisting the internal hydraulic pressure.Just because adding polymer can makeconcrete increase this ability,the methodis used to enhance the frost-resistanceseveral even tens times.
