摘要: 通过设计酸雨碳化耦合侵蚀制度(4S,3S-T,T-3S),探讨了碳化对混凝土受酸雨侵蚀速率的影响.研究结果:在设计试验制度下碳化能抑制混凝土受酸雨侵蚀速率,且性能变化规律基本上与受侵蚀程度变化规律一致;碳化主要是抑制了了水泥浆体受酸侵蚀时的"脱钙"过程;通过简化侵蚀条件可得出碳化作用抑制混凝土受酸雨侵蚀速率的最佳条件为3c

Abstract: Effects of carbonation on the corrosion speed of concrete by acid rain were studied by designing different coupling corrosion systems(4S, 3S-T, T-3S).The results show that concrete carbonation can inhibit the corrosion rate of acid rain, which is mainly due to the inhibition of the decalcification process, occurred when cement paste is corroded by acid rain;the macroscopic properties of concrete is basically consistent with the degree of erosion;by simplifying the erosion conditions, the optimum condition of 3c
