| Abstract: | An artificial acid rain environment is simulated with sulfuric acid solution，and then its impact on the performance of recycled concrete is tested and summarized.During the test，it is found out by the electrochemical workstation that the negative value of ecorr becomes larger，while the resistance value of the concrete protection layer becomes smaller，thus the corrosion rate is obviously increased.The data and the conclusion from the test lay a basis for the further study made on the impact from acid rain on the performance of recycled concrete and provide some references for the expanded application and the durability design of the recycled aggregate concrete. |
