灌浆液收缩和裂缝陈旧性对灌浆质量的影响

Size shrinkage and old cracks affecting the grouting quality

分析了灌浆液收缩和裂缝陈旧性两个影响灌浆强度的因素,表明这两个因素对灌浆粘结界面强度影响较大,提出了提高陈旧性裂缝灌浆质量的方法,从而更有效地延长混凝土工程的寿命。

This paper analyzes two factor（size shrinkage and old cracks） affecting the grouting intensity, it find that the two factor do more effect on felting interface intensity. At the last it propose an approach to improve grouting quality of old cracks. Thus prolonging the service life of concrete project better.
