环氧树脂具有强度高、粘合力强、收缩变形小、稳定性好、可室温固化等优点,因而在粘合剂等方面获得了广泛应用。环氧树脂作为灌浆材料于50年代末期美国首先应用,以后,日、德、法、英、苏、瑞士、西班牙及加拿大等许多国家都对环氧树脂灌浆材料进行了大量的研究工作和推广应用。我国于1959年也开始了这项研究工作。十多年来,我国已相继在水电、交通、建筑等部门较大规模地应用这个方法修补混凝土建筑物裂缝和加固岩石基础。特别是在修补混凝土裂缝方面应用十分普遍。正如有的同志所说“用量不大,但使用面很 Epoxy resin with high strength, strong adhesion, small shrinkage deformation, good stability, can be cured at room temperature, etc., which has been widely used in adhesives and so on. Epoxy resin as the grouting material was first applied in the United States in the late 1950s. After that, many countries such as Japan, Germany, France, Britain, the Soviet Union, Switzerland, Spain and Canada carried out a large amount of research work on the grouting materials of epoxy resin and promoted their application . Our country also started this research work in 1959. For more than a decade, our country has applied this method one after another to large-scale hydropower, transportation, construction and other departments to repair cracks in concrete buildings and reinforce the rock foundation. Especially in the repair of concrete cracks is very common. As some comrades said, "the amount used is not large, but the use of surface is very much
