Abstract: This paper analyzes the cracks of concrete construction classification, and introduces some common method of crack control.
Key words: concrete; crack; control; treatment
1 Introduction
Building construction, if the concrete cracks, it will affect the stiffness of concrete structures and buildings, the overall resistance of the structure, even the appearance of cracks in concrete structures will not cause damage or collapse of the building will affect the exterior of the building When the crack width exceeds a certain limit, can also cause corrosion, the durability of structural components. This article describes the construction of concrete crack control of several common methods and measures to deal with cracks on the concrete works have a certain reference value.
2, classification of common cracks

1、前言
建筑工程施工中,如果混凝土构件出现裂缝,就会影响混凝土构件的刚度和建筑物结构的整体抵抗能力,即使裂缝的出现不会导致混凝土构件的破坏或建筑物的倒塌,也会影响到建筑外观,当裂缝宽度超出一定限度时,也会造成钢筋锈蚀,影响结构构件的耐久性能。本文介绍混凝土工程施工中几种常见裂缝的控制方法及裂缝的处理措施,对混凝土工程的施工有一定的参考价值。
2、常见裂缝分类
混凝土裂缝产生的原因是多方面的,情况较为复杂,综合因素较多。对于某种裂缝的出现,人们很难给予一个准确明晰的原因分析。工程实践证明,裂缝形成的原因主要来自三个方面:变形、荷载以及不均匀沉降。一般由温差、收缩、不均匀沉降等引起的变形赞成的裂缝约占80%,荷载等造成的约占20%,当然还需要考虑其综合原因。根据这些主要影响因素,人们常把混凝土裂缝归纳为收缩裂缝、温度裂缝、沉降裂缝、徐变裂缝、应力裂缝和施工裂缝等几大类
