以大量实际工程调查结果为基础，通过理论分析与经验模式的对比，建立了二氧化碳在混凝土中的扩散系数与混凝土抗压强度的关系；进而利用氧气扩散与二氧化碳扩散的关系，给出了氧气在混凝土中的扩散系数与混凝土抗压强度的函数关系。 Based on the results of a large number of actual engineering surveys, the relationship between the diffusion coefficient of carbon dioxide in concrete and the compressive strength of concrete was established through the comparison between theoretical analysis and empirical model; then the relationship between oxygen diffusion and carbon dioxide diffusion was used to give the oxygen The relationship between the diffusion coefficient in concrete and the compressive strength of concrete.
