我们都知道环氧地坪漆施工对混凝土地面的要求比较高，要求混凝土水泥标号在C25以上、地面平整不存在起壳起砂等现象，但是对于环氧地坪漆施工小白来说并不清楚如何判断混凝土地面是否满足环氧地坪漆施工要求，下面环氧地坪漆厂家就给大家详细介绍。

We all know that the construction of epoxy floor paint has high requirements for concrete floor, requiring that the concrete cement label be above C25, and that there is no phenomenon of shell-raising and sand-raising on the surface, but it is not clear how to judge whether the concrete floor meets the construction requirements of floor paint for the construction of small white floor paint. The following epoxy floor paint manufacturer will give you a detailed introduction. 1、判断混凝土地面水泥标号是否达到标准的方法

1. The Method of Judging whether the Cement Label of Concrete Ground meets the Standard

最直接的办法就是向甲方询问混凝土材料的基础标号。或者用硬质的小工具(例如钥匙)刮，看混凝土刮痕深度，越深标号越低。

The most direct way is to ask Party A for the basic label of concrete materials. Or scrape with a hard tool (such as a key) to see the scratch depth of concrete, the deeper the scratch, the lower the label.2、判断混凝土地面是否存在起壳现象的方法

2. The Method of Judging Whether there is Shelling on Concrete Ground

对于混凝土地面起壳现象非常严重的一般是可以肉眼观察出来的。如果起壳现象不严重，可以通过踩、敲，看是否能听到空响声，如果有，则有起壳的地方。

The phenomenon of concrete surface shelling is very serious, which can be observed with the naked eye. If the phenomenon of shelling is not serious, you can step on and knock to see if you can hear the sound of empty, if there is, there are shelling places.3、判断混凝土地面是否存在起砂起灰现象的方法

3. Method of judging whether there is sand and ash on concrete floor

对于混凝土地面起砂起灰现象比较严重的，一般是可以通过肉眼看出混凝土表面不断有松散的水泥会和细碎的骨料脱落。如果肉眼无法观察到起砂起灰现象，可以用硬一点的扫把扫地面，看是否有起砂起灰现象。

For the serious phenomenon of sand and ash on the concrete floor, it can be seen by naked eyes that there are loose cement and fine aggregate falling off on the concrete surface. If the naked eye can not observe the phenomenon of sand and ash, you can use a harder sweep to sweep the ground to see whether there is sand and ash phenomenon.4、判断混凝土基础表面平整情况的方法

4. The Method of Judging the Surface Flatness of Concrete Foundation

判断混凝土地面平整度需要用到2m靠尺，将靠尺平放于地面上，把尺子平放于地坪基面，测量尺子与地面之间的间隙值，一般要求地面的凹凸度在2mm以下，若都小于这个范围，则地面平整度符合要求;若间隙值大于2mm，则需对地坪漆施工基面进行修补找平处理.

To judge the evenness of concrete ground, it is necessary to use 2m ruler. Place the ruler flat on the ground. Measure the clearance between the ruler and the ground. Generally, it is required that the concave and convex degree of the ground be less than 2mm. If the clearance value is less than 2mm, the ground evenness meets the requirements. If the clearance value is greater than 2mm, it is necessary to repair and leveling the construction base of the floor paint.
