This research conducts an indoor experiment simulation of acid rain and a comparative research on the influence of mineral additives,the curing time,and surface protection methods on the concrete mass loss,the compressive strength loss,and the neutralization performance.The results show that after adding mineral additives,the concrete specimen mass and the compressive strength loss reduce more than premixing concrete with only cement to a certain degree,and a better inhibitory effect can be achieved when fly ash and slag are added in appropriate proportion.It also indicates that the concrete specimen mass loss and the compressive strength loss can be reduced with the extension of standard curing time.The concrete specimen mass loss,the compressive strength loss,and the neutralization performance can be prevented when silicaneor coating is applied to its surface,and the effect of coating is better.
