In the process of construction and use, cracks appear in reinforced concrete structure, which affects the engineering quality. This paper analyzes the causes of cracks in concrete structures, and further puts forward the ventilation and control measures before cracks.

With the rapid development of China's national economy, reinforced concrete structures have been widely used in industrial and civil buildings for many years. However, cracks in concrete structures have always been a disease. In architecture, cracks are the most common and the most difficult to overcome. In some cases, cracks may lead to extremely serious consequences. Therefore, it is of great social and economic significance to study the cracks in reinforced concrete structures.

Concrete pouring plays an important role in modern engineering construction. However, today, concrete cracks of different degrees and forms are quite common in the construction process, which is particularly prominent in mass concrete construction, and the analysis and discussion on the influence of concrete construction temperature in winter has also begun, which belongs to a frequent period. This paper puts forward corresponding control methods and treatment measures for concrete cracks in winter construction, and discusses the characteristics and causes of concrete cracks in winter construction.
