建筑物内外墙体水泥砂浆粉刷层的龟裂、起壳并导致渗水的现象是建筑工程中的通病之一,它们不仅会影响建筑物的使用功能,损害建筑的外观形象,甚至影响到建筑物的使用寿命,要维修既耗时又费力,且收效甚微。墙面产生裂缝的原因比较复杂,主要有以下几个方面:①原材料及其配比:水泥在水化固结中会产生一定的收缩,是砂浆产生裂缝的根源,因此在其他条件相同的情况下水泥用量越多,收缩越大,
Cracking, hulling, and water seepage of the cement mortar coating layer inside and outside the building wall are common problems in construction projects. They not only affect the function of the building, damage the appearance of the building, and even affect the building. The service life is time-consuming and labor-intensive to repair, with little success. The causes of cracks on the wall surface are relatively complex. The main aspects are as follows: 1 Raw materials and their proportions: The cement will produce a certain shrinkage in the hydration consolidation, which is the root cause of cracks in the mortar. Therefore, other conditions are the same. The more cement is used, the greater the shrinkage,
