通过室内模拟酸雨试验，对比研究矿物掺合料、养护时间和表面防护方式对混凝土质量损失、抗压强度损失和中性化性能的影响。结果表明，掺入矿物掺合料后，混凝土试件质量和抗压强度损失比纯水泥配制混凝土有所降低，按适量比例复掺粉煤灰和矿粉抑制效果更优；延长标准养护时间，能减小混凝土试件质量和抗压强度损失；试件表面涂覆硅烷或涂层后均能抑制混凝土试件质量和抗压强度损失及中性化程度，涂覆涂层效果更优。

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.
