预防大面积混凝土裂缝的技术处理

The Technical Measures to Avoid the Crack of the Large Scale Concrete

随着城市建设的发展 ,大面积混凝土应用越来越普遍 ,但是大面积混凝土施工中常常出现裂缝 ,因而影响了质量。裂缝产生的主要原因是混凝土硬化过程中的收缩 ,为了防止裂缝 ,应优化设计方面的构造措施、混凝土配合比设计措施及现场施工措施。文章结合工程实例 ,有针对性地对地下室混凝土墙体裂缝控制 ,提出了技术处理措施。

With the development of city construction, the large scale concrete has been applied more and more common. However, the crack, mainly caused by the contraction during the course of the induration in the large scale concrete, has often affected the construction quality. Therefore, a series of measures should be taken to avoid the crack problem. Connected with the practical construction, the paper objectively advances the technical measures to control the crack of the concrete wall in the basement.
