| Abstract: | FANG Jing, WU Shi-xiangAbstracr:Based on experimental rezults, by which the law of decreasing dynamic elasticity of Concrete is revealed under freezing and shawing, the effect of air-entrained micropores on euhandcing the frost resistance of concrete is analysed. And the failume patterns, both collapse for ordinary concrete and gradually develope for air-entrained concrete, and their mechanism are described. |
