According to the concrete wall crack causes and treatment measures Abstract: the mass concrete structure, shape big, thick reinforced dense, concrete the features of the quantity, but also has long structure deformation temperature conditions, complex temperature crack control of the high demand characteristics. The concrete construction quality supervision control the key is how to adjust measures to local conditions to take effective measures to prevent the construction technology and the deformation of the concrete temperature crack control occurrence and development. Keywords: large area concrete engineering; The basement; Crack; Processing measures; Quality With the high speed development of city construction, large area basement concrete structure engineering more and more. At present the basement wall cracks of concrete high-rise building was common, not only for leakage and effect use, still can reduce the durability. Concrete component project as the main structure of the concrete quality is an important part of guarantee and realize their own structure unit engineering safety and use function of the key. Mass concrete crack is the main reason of the concrete during hardening cement hydration process of the release of the hydration heat make its surface temperature appear non-uniform temperature difference have formed and tensile stress cracks of concrete temperature deformation restrictions. How to take effective measures to prevent the construction technology and the key is to control the temperature cracks. Combined with the engineering practice in recent years, large area basement of cracks in the concrete temperature deformation quality control, and talk about some work methods and experience. First, A main reason, the crack 1. The concrete shrinkage factors From the crack characteristics belong to the most visible shrinkage crack. The basement concrete wall of large contraction of the main causes of the dosage of cement too much, maintenance defi
