随着我国经济水平的不断发展,外墙材料日益更新。在主要使用的外墙砖工程中,建筑物外墙渗漏现象比较突出,直接影响建筑工程质量,同时渗漏的产生也影响了建筑物的功能,对室内装饰造成霉烂脱落,影响建筑物的使用。而这些渗漏的产生除了墙体砌筑、外墙砖铺贴不规范、窗台等细部节点构造工程处理不合理等引起外,墙体装饰层开裂即外墙水泥砂浆开裂是造成渗漏的主要原因之一,危害性很大。1.水泥砂浆裂缝产生的原因1.1原材料选材及配料不当一些施工单位在施工中对建筑物的梁板、柱等选用较好的水泥和
With the constant development of our country’s economic level, the materials of the external walls are getting more and more updated. In the main use of external wall brick projects, the external wall of the building has a more prominent phenomenon of leakage, which directly affects the quality of the building project. At the same time, the leakage also affects the function of the building, causing rottenness and detachment of the interior decoration, affecting the building’s use. The occurrence of these leakages is caused by the irregular construction of wall masonry, external wall tiles, and the irrational treatment of detail joints of windowsills. The cracking of the wall decoration layer, that is, the cracking of the external wall cement mortar is the main cause of leakage. One of the reasons is very dangerous. 1. Causes of Cracks in Cement Mortar 1.1 Inadequate selection of raw materials and ingredients Some construction companies choose better cement and beams for building beams, columns, etc. during construction.
