摘要
本文以环氧树脂作为粘结剂,研究胶粘拉拔法新检测技术.为探索胶粘拉拔法可靠性,与其他非破损检测方法测试结果进行对比分析.研究结果表明,胶粘拉拔法的混凝土拉拔力与其抗压强度具有良好的相关性.检测新老结构混凝土强度具有良好的应用价值.
In this experimentt Epoxy resin was taken as a adhesion agent,with which the drawn fest piece and concrete are boud together,and the adhesion-drawing method as a new one has been presented.For exploring the reliability of this metthod,it was contrasted to the other undamaged experimental ways.Through the test results and the analysis it is shown to be that by means of the adhesion-drawing method the drawing force for the test piece in cocrete has a close interrelation to the compressive strength of concrete.Therefore,the above-mentioned method will be of gread use value in checking concrete strength of new and old reinforced concrete structures.
