摘　　要：混凝土碳化会导致混凝土中的钢筋脱钝,从而引起钢筋锈蚀,最终影响到混凝土结构的耐久性。该文对环保型裂缝修复材料处理试件进行了抗碳化性能试验。试验结果表明:相比普通混凝土试件,ECRM处理后试件的碳化深度减小,且混凝土碳化速率提前出现下降趋势,ECRM能有效增强混凝土的抗碳化能力。Concrete carbonation is always lead to the depassivation and corrosion of concrete reinforcing bars. Ultimately affect the durability of the concrete structure. This paper made a carbonation resistance test to concrete specimens that treated by ecological crack restoring material（ECRM）. It is found that, compared with ordinary concrete specimens, the carbonation depth of specimens coated with ECRM are decreased. Moreover, concrete carbonation rate declined in advance. ECRM can enhance the resistance carbonation ability of concrete effectively.
