摘要

Freeze-thaw cycles have the impact on mechanical properties of the concrete in northern areas of China. In this paper, on the basis of the damage degree of freeze-thaw cycles and experiment data, for C30～ C50 concrete after freeze-thaw cycles, the loss rate of relative dynamic elastic modulus and the relation between compressive stress-strain are analyzed. Compounding good frost resistance of concrete is one of important measures to improve durability of concrete, and degradation patterns of mechanical properties are found. This study may serve as prediction of the service life of concrete in cold regions.
