我国南方许多地方每年2～8月份是多雨天气,尤其是春、夏和梅伏天,更是阴雨连绵。此时是每年的高湿季节,地下水位也上升。这种地区建筑物的地面防潮处理不好,就会给生产、生活带来极不利的影响。室内潮湿的原因是多方面的,如空气潮湿、室外的排水不畅、房间的通风不好等,而地下水因毛细作用反湿到地面是重要原因。南方大部分地区地表层多属粘土和亚粘土。粘土毛细孔水位上升高度可达5～6米,亚粘土则达3～3.5米。密实性差的建筑材料做室内地面,会增加毛细作用,地面反潮严重。为了防潮,常在混凝土中加防水剂,做成防潮混凝土底层,再抹水泥砂浆面层;也有的刷冷底子油和
Many places in southern China are rainy from February to August each year, especially in spring, summer and Mayu days, and it is rainy. This is the annual high humidity season, and the groundwater level also rises. In this area, the building’s ground moisture treatment is not good, and it will have extremely adverse effects on production and life. There are many reasons for indoor humidity, such as damp air, poor outdoor drainage, poor ventilation of the room, etc., and groundwater is an important reason for anti-wetting to the ground due to capillary action. Most of the southern part of the surface is mostly clay and sub-clay. The height of the water in the clay capillary rises up to 5 to 6 meters, and the subclay reaches 3 to 3.5 meters. The use of poorly-constructed building materials for indoor flooring will increase capillary action and cause severe anti-tide on the ground. In order to prevent moisture, often add water repellent in concrete to make moisture-proof concrete bottom layer, and then wipe the cement mortar surface layer; also some brush cold oil and
