Gansu Province is located in a cold, dry and windy area. The whole province is dry with little rain, large temperature difference between day and night, and long cold time. The quality of raw materials used for concrete is unstable, and cracks exist in all kinds of building concrete walls, which has a great impact on the quality and forming effect of buildings, and there are many types of concrete cracks. In order to improve the problem of concrete cracks, we need to start from the causes of concrete cracks. The most effective way to control and reduce concrete cracks is to correctly judge and analyze the causes of concrete cracks. Through the study of concrete: raw material properties, mixture properties, mechanical properties and other factors and the relationship between cracks. At the same time, two kinds of structural measures are added in the construction site, i.e. reinforcing mesh and concrete curing method, to study their influence on concrete cracks.
