    环氧地坪施工各环节指标分别是什么?

    混凝土基础底面的地面状况对最终环氧地坪工程质量影响很大,此外,环氧地坪施工过程中其它各个环节也有严格的指标。下面车库地坪施工方详细介绍下环氧地坪施工各环节指标分别是什么?
    The ground condition of the concrete foundation bottom has a great influence on the final epoxy floor engineering quality. In addition, there are strict indicators in other links of the epoxy floor construction process. What are the indicators of each link in the construction of the lower epoxy floor detailed by the garage floor builder?
    地面平整度一般要求在2m范围内落差不大于2mm最好用抹光机抹平并收光;如落差较大,则环氧地坪涂层需加厚以减小落差。如需涂装的地面处于底层,地下水位较高,则混凝土底层应做好防水处理,避免地下水上升形成的蒸汽压顶起地坪涂层而引起起泡、起壳现象。

    Generally, the ground flatness requires that the drop within 2m should be no more than 2mm. It is better to use a trowel to level and polish; if the drop is large, the epoxy floor coating needs to be thickened to reduce the drop. If the ground to be coated is at the bottom and the underground water level is high, waterproof treatment shall be carried out for the concrete bottom to avoid blistering and shelling caused by the steam rising from the underground water pushing up the floor coating.

    新建混凝土干燥至少3周以上,含水率不高于6%,且在养护干燥过程中避免局部淋雨及地面积水,否则易引起局部混凝土水分含量超标。楼板、钢筋混凝土梁等构件上的细石混凝土找平层强度不应低于C20,厚度不低于0mm。
    The newly-built concrete shall be dried for at least 3 weeks with moisture content not higher than 6%, and local rain and ground water accumulation shall be avoided in the process of curing and drying, otherwise the moisture content of local concrete may exceed the standard. The strength of fine aggregate concrete leveling layer on the floor slab, reinforced concrete beam and other components shall not be less than C20, and the thickness shall not be less than 0mm.
    对损坏的混凝土表面修补或找平时,应采用强度等级不小于的细石混凝土,找平厚度不应小于;需用水泥砂浆找平时,应先涂一层混凝土界面处理剂,再按设计厚度找平。当施工过程不宜进行上述操作时,可采用树脂砂浆或聚合物水泥砂浆找平。
    For repair or leveling of damaged concrete surface, fine aggregate concrete with strength grade not less than shall be used, and the leveling thickness shall not be less than; for leveling with cement mortar, a layer of concrete interface treatment agent shall be applied first, and then the leveling shall be conducted according to the design thickness. When the construction process is not suitable for the above operations, resin mortar or polymer cement mortar can be used for leveling.
