Research on neutralization mechanism of concrete subjected to acid rain

There are a great number of concrete structures existing in the atmospheric environment. The process of industrialization has led to the severe air pollution. The acid rain areas expand so severely that the neutralization of concrete is increasingly concerned about. Acid rain is the most ordinary acidic material in the atmospheric environment. In this paper, the neutralization process of acid rain was analyzed through the theory of diffusion and mass transfer, and the neutralization mechanism of concrete acid rain eroded was revealed, which is significant for the durability design and for the further investigation of reinforcement corrosion and service life prediction of concrete structures.
