建筑物正面出现蜂窝麻面,使人看起来很不顺眼。减少建筑物正面的蜂窝麻面实际上很容易,通常又不增加费用,也不会影响混凝土强度。提高混凝土表面的质量方法有两:一是注意使用的有关材料,二是改进一下施工方法。蜂窝麻面的类型及形成的原因空气、水和脱膜剂是形成蜂窝麻面的三种因素。气孔在模板与混凝土之间,若有残留空气,就会形成蜂窝麻面。在不规则的骨料之间,常有残余空气存在,若加上混凝土的坍落度低,就可能出现大面积的蜂窝麻面。蜂窝麻面在区域、位置和大小等方面都没有规
The appearance of cellular pockmarks on the front of the building makes people look unpleasant. It is actually very easy to reduce the number of cellular plinths on the front of a building, usually without increasing costs, and without affecting the concrete strength. There are two ways to improve the quality of concrete surfaces: one is to pay attention to the relevant materials used, and the other is to improve the construction methods. The type of honeycomb puddles and the reasons for their formation Air, water, and release agents are three factors that form honeycomb puddles. The pores form honeycomb pockmarks between the formwork and the concrete if there is residual air. Between the irregular aggregates, residual air is often present. If the concrete slump is low, a large area of cellular pockmarks may appear. There is no regulation in the area, position and size of honeycomb pockmarks
