混凝土表面起砂处理方法

Sanding method for concrete surface

处理混凝土表面起砂的主要做法为: 将起砂的位置清理到结构层, 之后根据具体工程采用适宜的方法对起砂的部位进行修补加固。具体做法如下。

The main way to treat the sand on the concrete surface is to clean up the location of the sand to the structural layer, and then repair and reinforce the location of the sand according to the specific engineering. The concrete practice is as follows.

1) 清理

1) clean up

对混凝土表面起砂的区域, 应先将表面的浮尘及浮浆清理干净, 并且用水冲洗。然后对清理后的混凝土进行打磨, 打磨到坚硬的表面为止。

In the area where the surface of the concrete is sanding, the surface of the dust and the floating slurry should be cleaned up, and the water should be flushed with water. Then the cleaned concrete is grinded and grinded to the hard surface.

2) 修补

2) repair

先将打磨出来的浮尘清理干净, 然后用水冲洗,等晾干后，采用一种液体水溶性的混凝土密封固化剂对起砂部位进行处理, 这种硬化剂通过渗透起作用, 进入混凝土中形成致密结晶体, 从而提高混凝土的强度。

The first grinding out the dust clean, then rinse with water after drying, etc., using a liquid water soluble concrete for processing parts sand seal curing agent, the curing agent through the penetration effect into dense crystalline body formed in concrete, so as to improve the strength of concrete.
