非顺筋裂缝对混凝土结构耐久性影响的调查分析

混凝土结构在建筑工程中广泛应用,而裂缝是混凝土的常见病和多发病,亦是导致混凝土结构耐久性降低的主要因素之一。本文通过对混凝土非顺筋裂缝的产生过程及类别特征进行了分析,并对浙江宁波地区部分建筑物进行了实地调研,对建筑物中存在的主要非顺筋裂缝进行了分析讨论,论述了混凝土非顺筋裂缝对结构耐久性的影响。

Concrete structure is widely used in the architectural engineering, and con- crete crack is the common diseases and frequently - occurring diseases, also is one of the main factors that caused concrete structure durability reduced. This paper through to the cracks of the concrete generation process and category feature, and discussed the influence of the non longitudinal cracks on the durability of concrete structure.
