| 摘 要： | 混凝土裂缝几乎是不可避免的，但大部分裂缝均可通过修补使混凝土结构恢复原有功能。本研究分别采用玄武岩纤维水泥砂浆结合灌浆法对受弯混凝土梁进行了综合修补裂缝试验研究对比，结果发现，这种新的修补方法可使新补混凝土层中的收缩裂缝与受力裂缝得到明显控制，使修补结构获得良好的整体性，明显提高粘结界面的抗疲劳性能，使修补结构的耐久性得到有效提高。

| Abstract: | It's almost inevitable for concrete structural cracks to happen.But most of cracks can be patched and thus concrete structures can restore their original function.Experimental research on crack repair to concrete beams is conducted in the way of a combination of basalt fiber cement mortar and grouting method.Results show that shrinkage cracks and stressed cracks can be obviously patched,repaired structures also can obtain a good integration,bonding interface crack resistance can be obviously enhanced,and th... |
