浅述商品混凝土裂缝的形成与预防

随着城市化的建设和建筑技术的发展,建筑规模逐渐扩大,楼房的层数不断增高,混凝土的设计强度标号也随之增大,加之施工现场越来越小,而商品混凝土作为建筑半成品的主要材料,以其质量可靠,施工方便,节省施工现场,提高施工效率,节能环保等特点,商品混凝土已被建筑市场广泛采用,但商品混凝土裂缝问题已成为工程结构的一个普遍质量问题,且日趋增多。本文通过庆阳市建设大厦工程实例,分析裂缝的形成,从源头着手达到预防和控制的目的。

The Formation and Prevention of the Commercial Concrete Crack

With the development of the urbanization construction and construction technology, construction scale expands gradually, the number of layers in building is increasing, the design strength grade of the concrete is increased, and the construction site is more and more small, and the commercial concrete is as the main material of building semi-finished products, with its features of reliable quality, convenient, saving the construction site, improving construction efficiency, energy conservation and environmental protection etc., it has been widely used in construction market, but the commercial concrete crack problem has become a common quality problem of engineering structure, and is increasing. Based on the project example of Qingyang building construction, it analyzes the formation of cracks, so as to achieve the goal of prevention and control from source.
