目前预制混凝土墙板在工业厂房及居住建筑中的应用日益广泛,其设计计算、构造措施和施工要点均有相应的规范可循。但在预制混凝土墙板的裂缝分类、开裂原因及预防控制方面的专著不多,本文拟就这个问题作一简单介绍,供参考。一、前言美国凯里(Kelly)教授在《混凝土中的裂缝——其原因与防治》一文的开头就说:“我们大多数人要得感冒,而大多数混凝土都会开裂。尽管感冒,我们还得去办
At present, the application of precast concrete wall panels in industrial plants and residential buildings has become increasingly widespread. The design calculations, structural measures and construction points have corresponding specifications to follow. However, there are not many monographs on crack classification, cracking causes, and prevention and control of precast concrete wall panels. This article is intended to give a brief introduction to this issue for reference. I. INTRODUCTION Prof. Kelly said at the beginning of the article “Cracks in Concrete: Its Causes and Prevention”: “Most of us have a cold and most concrete cracks.
