摘　　要：通过混凝土快速碳化试验 ,针对南京地铁主体工程的C30泵送混凝土 ,研究了粉煤灰和矿渣微粉对混凝土抗碳化耐久性的影响 ,从而论证南京地铁主体工程钢筋混凝土结构抗碳化耐久性可满足100年的设计使用寿命。Based upon the experiment of fast carbonation test of C30 pumpcrete, which is used in Nanjing Subway's project, the influence of fly ash and ground-granulated blast furnace slag(GGBS) on the concrete durability for carbonation resistance is studied, and the rezults show that the concrete can meet the demand of designed life-span of 100 years.
