冻融损伤后混凝土自愈性能的试验研究

摘要

This paper researches the self - healing performance of concrete under freeze-thaw damage. It describes the self - healing performance with the compressive strength and studies the microstructure change of concrete with SEM. The result shows that the compressive strength of different - strength concrete improves through proper maintenance under freeze -thaw damage.%探讨了混凝土冻融循环损伤的自愈性能。以抗压强度值表征混凝土的自愈性能，并利用扫描电镜对混凝土微观结构的变化进行了观测。试验结果表明，冻融循环作用后，经过适当的养护，不同强度等级混凝土的抗压强度均有提高。
