Prevention And Control of Mass Concrete Cracks in Building Construction Engineering

Abstract

As a kind of building material, mass concrete plays an important role in building construction. It is widely used in engineering projects and needs to be controlled in many aspects, otherwise cracks may appear and affect the safety and performance of the project. In this paper, the crack problems of mass concrete structures are studied and analyzed, such as cracks caused by mix ratio, temperature change, foundation deformation. Firstly, by understanding the internal and external causes of cracks in mass concrete, the key issues were suggested. Then, the method to prevent and control the crack of mass concrete is put forward from the selection of reasonable raw materials and mix ratio, pouring method, temperature control and other aspects. The research results can be used as reference to reduce the negative impact of cracks in building construction engineering. While improving the safety and service life of housing construction projects, it also improves the economic value and reduces the time cost of rework.
