混合结构房屋在混凝土的施工中常常出现一些质量通病,这些通病既有管理上的,又有技术上的,还有操作上的。本文分析一些混凝土质量通病的危害,并提出预防措施。1.粗集料粒径过大,级配不良,粉尘、杂质含量多。材料的这些先天性缺陷,使粗集料与水泥石的粘结变差,造成界面微裂缝增多,导致厨房、卫生间等现浇结构渗漏,同时,还降低了混凝土的强度。解决粗集料问题,首先应建立健全材料
Mixed-use houses often show some common faults in the construction of concrete, which are both managerial, technical and operational. This article analyzes some of the hazards of concrete quality problems, and put forward preventive measures. 1. coarse aggregate size is too large, poor grading, dust, impurities and more. These congenital defects in the material make the bonding of the coarse aggregate and the cement stone worse, resulting in the increase of micro-cracks in the interface, resulting in leakage of the cast-in-place structures such as the kitchen and the bathroom, and also reducing the strength of the concrete. Solve the problem of coarse aggregate, we must first establish and improve the material
