混凝土楼面板中的水份是养护所必不可少的,但对于楼面防水层材料(如油毛毡,油漆、涂料、封闭剂等)与基层的粘结、施工后的楼面稳定情况等却是有害的.楼面防水材料有时会受到混凝土中碱性水份的腐蚀或粘结性遭到破坏。因此在进行防水层施工前希望能测定出混凝土楼面板的干燥情况。下面介绍国外几种常用的湿度简易测定方法。 Water in the concrete floor slab is essential for conservation, but it is for the bonding of the floor waterproof layer materials (such as oil felt, paint, coating, sealant, etc.) and the grass-roots level, and the floor stability after construction. Harmful. Floor waterproofing materials are sometimes damaged by the corrosion or adhesion of alkaline water in the concrete. Therefore, it is desirable to measure the dryness of the concrete floor before the construction of the waterproof layer. The following describes several commonly used methods for measuring humidity in foreign countries.
