Life Prediction of Existing Concrete Structures in Acid Rain Environment

Abstract

Abstract. In the paper based on diffusion theory the acid rain erosion-carbonization model was established. The model parameters were analyzed and the model was solved by MATLAB software. At same time the failure criteria of existing concrete structure in acid rain area was developed and the life prediction method was proposed. Finally, combined with the acid rain feature in Nanchang the multi-storey teaching building life was predicted to prove the validity of the model. The calculation showed the acid rain damage to the building in Nanchang is more serious. It should be taken seriously enough.
