The fineness gradation of the concrete cementing material has an extremely important influence on the durability of the concrete material, and is used in the processes of concrete mixing, pouring and engineering construction. In order to ensure the structure and quality, the grinding of the cementitious material is mostly required to improve the performance of the concrete, microscopically, the pores and pores including the cementitious pores are inevitably generated in the forming process of the concrete, the permeability of the pores is greatly increased under the condition of communication, and the physical and chemical reactions generated by the invasion of harmful media can greatly and negatively influence the durability of the concrete. However, the study of the scholars at home and abroad shows that the permeability of the concrete is improved. One method is to reduce the fineness and the particle size of the gelled material by grinding the gelled material, so that the material with extremely small fineness and particle size can block pores in the process of maintaining and forming the material, thereby achieving the purpose of reducing the permeability of concrete.
