Study on Neutralization Model for Fly Ash Concrete Subjected to Acid Rain
Based on the theory of diffusion and mass transfer, a theoretical neutralization model for fly ash concrete eroded by acid rain was proposed. The values of the model parameters were studied, and the calculation formula of effective diffusion coefficient DA was established considering both material and environmental aspects. The model was verified by acid rain erosion test results, and the results calculated by the model agree well with test results. The model proposed in this paper can be used to predict neutralization depth of fly ash concrete subjected to acid rain attack.
