一、渗漏的原因1.外墙面砖的质量差。作为外墙面砖应是质地坚硬的瓷砖,具有防水功能,但是也有一些劣质的泥质瓷砖,质地疏松,吸水率大,时间一长,釉面就会出现微细裂缝,接着出现粉皮、脱皮,不但起不到防水的作用,反而起着吸水、蓄水的反作用。2.砂浆质量控制不严。砌筑和抹灰用的砂浆用含泥量较大的砂来拌制,其粘性大,收缩性大,降低砂浆强度,砂浆会因收缩大而产生开裂。砂浆配合比不准确,材料任意加减,搅拌砂浆时间不足,更加导致砂浆强度下降和不均匀,另外在同一施工面上,出现不同的收缩率也会引起开裂和空鼓。
First, the reasons for leakage 1. The quality of exterior tiles. As the external wall tiles should be hard texture tiles, with waterproof, but there are also some poor quality clay tiles, loose texture, water absorption, over time, there will be fine cracks in the glaze, followed by vermicelli, peeling, Not only failed to play the role of waterproofing, but plays the role of water absorption, water storage reaction. 2 mortar quality control is not strict. Mortar for masonry and plastering is mixed with sand with a large amount of mud, which is highly viscous, highly shrinkable, and lowers the mortar strength. The mortar cracks due to large shrinkage. Mortar mix is not accurate, arbitrary addition and subtraction of materials, mixing mortar time is not enough, leading to a decline in mortar strength and unevenness, the other in the same construction surface, there will be different shrinkage rate will cause cracking and hollowing.
