摘　　要：利用试验的方法,针对不同配合比的混凝土及不同配方的环氧树脂灌浆材料做了一定研究,从而找出一组最佳的环氧灌浆材料配比,以使预埋管混凝土裂缝的粘结达到最佳效果。研究表明:混凝土劈裂粘结强度的大小和混凝土配合比无关,而和树脂浆液的配比有关;在室温养护条件下,三种配方浆液的粘结拉伸强度均较高;在劈裂粘结强度测定中,醛-丙酮稀释体系浆液显示出更好粘结效果。Researches have been made with experimental methodology on different concretes and epoxy resin grouting materials. A better proportion of epoxy resin has been found to make better results on the adhesive of embedded pipe concrete crack. The results indicate： there is no relationship between bond splitting strength and mix proportion of concrete, but bond splitting strength is associated with proportion of epoxy resin ; in the condition of ordinary temperature, strengths of the three proportions of epoxy resin are strong; in the test of bond splitting strength, furfural - acetone turns out to be of better effect.
