1、 The causes, prevention and treatment of cracks in concrete Abstract: In the building construction concrete cracks a quality common problem, the causes of cracks in concrete, prior prevention, as well as after the repair process is a more common phenomenon in the process of building production, shou
2、ld be taken seriously enough. The concrete is a brittle material of a gravel aggregate, cement, water and other additional material formed by mixing a non-homogeneous. Concrete construction and deformation constraints and a series of problems, there are a large number of micro-porosity, cavitation a
3、nd micro-cracks in the concrete hardening molding. The author combines his engineering work experience, summed up the cracks in concrete causes and prevention measures. Keywords: causes of cracks in concrete preventive treatment In building construction, concrete cracks is a widespread problem, crac
4、ks solution is a more difficult problem. Cracks in concrete reasons are manifold, deformation: such as contraction, expansion, settlement and other causes cracks; external load caused by: improper maintenance of concrete; cracks caused by the external additive problems. Concrete cracks, if not preve
5、ntion measures to solve, extending its further development will lead to the internal reinforcement corrosive, reducing the carrying capacity of the reinforced concrete structure, impermeability, durability useful life, and even affect peoples lives and property safety . Crack is impossible to comple
6、tely eliminate the engineering specification expressly provides some structure in which the different conditions, allowing the existence of a certain width and depth of the crack. But in the construction process should be as far as possible to take effective preventive and technical safeguards to ef
7、fectively control the cracks, as little as possible or minimize crack width, depth, and in particular to avoid in key positions or harmful cracks. 1.Causes and types of concrete cracks The concrete is a brittle material of a gravel aggregate, cement, water and other additional material formed by mix

Hardening molding concrete concrete construction and deformation constraints there are a large number of micro-porosity, cavitation and micro-cracks, precisely because of the existence of these initial defects before the concrete showing some heterogeneity characteristics .
