摘要
为降低冻融与硫酸盐耦合作用对再生混凝土性能的影响,分析了导致混凝土劣化的机理,指出了协同作用对混凝土物理外观、质量变化、抗压强度、抗弯抗拉强度、损伤深度等方面的影响,提出提高混凝土抗劣化性能的措施,为进一步提升混凝土在寒冷环境下的耐久性提供参考。
In order to decrease the influence of the coupling of freeze thawing and sulfate on the performance of recycled concrete,the study analyzes the mechanism of concrete degradation;points out the synergistic effect on the appearance,quality change,compressive strength,bending resistance and extension strength,and injury depth,etc.;and proposes the measures for improving concrete resistance,to provide reference for the improvement of durability of concrete in cold environment.
