Abstract
In this study, the key factors and influencing factors of chemical erosion resistance of concrete were discussed. The connotation of chemical erosion resistance of concrete is analyzed in detail, including the chemical composition, structure, mechanism and type of chemical erosion resistance of concrete. Through systematic analysis, it is clear that the core of concrete resistance to chemical erosion lies in its material composition, environmental conditions, construction technology and structural characteristics. In the study, it is found that there are many problems in the chemical erosion resistance of concrete, such as the material composition is not suitable, the pore structure is poor, the mechanical properties decay and the service life is shortened. In response to these problems, this study proposed targeted optimization strategies, including material selection and mix design, surface protection treatment to improve pore structure, construction process improvement to enhance mechanical properties, and regular maintenance and repair to extend service life. By implementing these optimization strategies, this study aims to improve the chemical erosion resistance of concrete and ensure its durability and stability in practical applications. It also provides important theoretical basis and practical guidance for the research and development, production and use of concrete materials, which is of great significance for promoting the sustainable development of concrete technology.
