Abstract: The construction industry is a pillar of the relations to Guojiminsheng of basic industries. Particularly as China is in rapid development stage, the whole country have stepped up infrastructure construction. At the same time stimulating the economy with the construction industry as an important force in the pace of development, the construction industry is in a phase of great development. Because of their extensive concrete material, low-cost, high compressive strength, pouring into a variety of shapes, and the fire resistance of the good and not easily weathered, conservation low-cost, a building structure in the world today the most widely used one of the building materials. With the birth of ready-mixed concrete, because of its convenient and quick construction, stable performance, reliable, low labor intensity, high efficiency, while at the same time reduce noise and protect the environment comprehensive advantages, Geng Shiba concrete to a peak. However, a lot of theory and practice of engineering analysis showed that the reinforced soil coagulation components are basically working with the cracks. Cracks control of reinforced concrete construction is a very important one of the issues, the study of concrete cracks the cause and prevention measures, control is very important and urgent.
