钢筋混凝土裂缝控制问题是建筑工程中很重要的问题之一,如何解决这种常见的混凝土裂缝,是设计者和施工者都不可忽视的重要课题。随着水泥工业和混凝土技术的进步,特别是最近20年来,泵送商品混凝土获得广泛应用之后,在混凝土均质性有了很大改善的同时,裂缝控制技术难度也大大增加了,过去在混凝土楼板中不突出的裂缝问题,近年来却日趋严重,甚至在一些地区成了质量通病,许多工程设计和施工人员对此很困惑。按理说混凝土技术进步了,原来
Crack control of reinforced concrete is one of the most important problems in construction engineering. How to solve this common concrete crack is an important issue that designers and constructors can not ignore. With the progress of cement industry and concrete technology, especially in the recent 20 years, the commercial application of pumping concrete has been widely used, the homogeneity of concrete has been greatly improved, and the difficulty of crack control technology has also increased greatly. In the past, The lack of prominent cracks in the floor has become increasingly serious in recent years, and even in some areas it has become a common problem of quality. Many engineering designers and constructors are confused. Logically speaking, concrete technology has improved, the original
