再生骨料混凝土结构出现裂缝后,构件承载力受到影响,本文对再生骨料混凝土结构裂缝进行了统计,得出了工程中再生骨料混凝土结构裂纹产生的原因与分布规律,并对常用裂缝修复技术抵抗二次开裂能力进行了对比试验,对再生骨料混凝土裂纹进行了研究,得到了修复准则,可直接指导实际工程应用。
After the occurrence of cracks in the recycled aggregate concrete structure, the bearing capacity of the members is affected. In this paper, statistics are made on the cracks in the recycled aggregate concrete structure. The causes and distribution of the cracks in the recycled aggregate concrete structure are obtained. Technical resistance to secondary cracking ability of the comparative test carried out on the recycled aggregate concrete cracks were studied to obtain the repair guidelines can directly guide the practical application.
