通过对３根混凝土梁、２个混凝土节点试件在模拟灾害性荷载作用下开裂后，采用环氧水泥快速修复的实例，对修复后的梁进行静力试验和２００万次疲劳试验研究，对修复后的节点进行反复荷载抗震试验研究，结果表明修复后强度不低于原试件，刚度提高，而最重要的是改善了破坏形态，从原来的脆性转为修复后的延性。 After three concrete beams and two concrete node specimens were cracked under simulated catastrophic loading, using the example of quick repair of epoxy cement, static tests and 2 million fatigue tests were conducted on the repaired beams. The repaired joints were subjected to repeated load seismic tests. The results showed that the strength after restoration was not lower than that of the original specimens, and the stiffness was improved. The most important thing was to improve the failure morphology, from the original brittleness to the repaired ductility.
