Method for repairing concrete cracks by grouting Portland cement
The invention discloses a method for repairing a concrete crack by grouting Portland cement. The method comprises the following steps that a mixed solution of Portland cement and water is grouted and injected into the concrete crack, and the operation is stopped when redundant water seeps from the crack; and after the water surface of the crack descends, the operation is repeated until the crack is completely repaired, and the concrete crack is repaired by the cured cement. The mass ratio of the Portland cement to the water is 1: 2. The ordinary Portland cement used for repairing the crack is cheap, easy to obtain, economical and practical. The cement grouting repairing process is simple and easy to operate, harmful substances are not generated, the environment-friendly effect is achieved, the expansion coefficient is similar to that of concrete, and generally secondary cracks are not generated.
本发明公开了一种硅酸盐水泥灌浆修复混凝土裂缝的方法，该方法利用硅酸盐水泥与水的混合液，灌浆注入混凝土裂缝中，当多余的水从裂缝中渗出时，停止操作；裂缝水面下降后，重复上述操作，直到裂缝修复完全，固化后的水泥修复混凝土裂缝。所述硅酸盐水泥与水质量比为1:2。本发明修复裂缝使用的普通硅酸盐水泥廉价易得，经济实用。水泥灌浆修复过程简单易操作，而且不会产生有害物质，环境友好，而且与混凝土的膨胀系数相近，一般不会产生二次裂缝。
