混凝土结构的裂缝一直是混凝土耐久性的一大威胁。混凝土的开裂是一个随机过程，变化很大，受多种因素的影响。裂缝修补方法包括通过注入或重力填充使用环氧树脂，以粘合裂缝并恢复其结构完整性。在使用环氧化合物之前，由于环氧树脂系统的多功能性和广泛的可用物理和化学性质，在进入环氧树脂世界之前必须完全了解和了解;除了裂缝修复，环氧化合物在混凝土工业中有各种各样的用途。在这项研究中，15个混凝土立方体，6个包括裂缝没有修复，6个包括裂缝与重力填充环氧树脂粘结和3个没有裂缝被压碎，并获得其抗压强度。结果发现，裂缝引起的压缩强度降低高达40.93%，而环氧树脂系统，当适当地应用，恢复压缩强度降低到8.23%。(c)2005爱思唯尔有限公司保留所有权利。
Cracks in concrete structures have always posed a big threat on the durability of concrete. Cracking of concrete is a random process, highly variable and influenced by many factors. Among the crack repair methods is the use of epoxy either by injection or by gravity filling in order to bond the crack and restore its structural integrity. Prior to the use of epoxy compounds and due to their versatility and the wide range of available physical and chemical properties of epoxy resin systems, one has to be completely aware and informed before entering the world of epoxies; other than crack repair, epoxy compounds have found a wide variety of uses in the concrete industry. In this study, 15 concrete cubes, six including cracks without repair, six including cracks bonded with gravity filled epoxy and three with no cracks were crushed and their compressive strengths were obtained. It was found that the cracks caused a reduction in compressive strength up to 40.93% whereas the epoxy system, when properly applied, restored the compressive strength by decreasing the reduction down to 8.23%.
