摘　　要：在与相同配合比的普通硅酸盐水泥混凝土的对比试验中,采用抗渗试验和孔结构分析的方法,研究了阿利特-硫铝酸钡钙水泥混凝土的抗渗性能与水灰比的关系。结果表明,阿利特-硫铝酸钡钙水泥混凝土的相对抗渗系数与水灰比的关系与普通硅酸盐水泥混凝土类似,即随着水灰比的增大而增大;在相同配比和养护龄期条件下,该水泥混凝土的抗渗性能明显优于普通混凝土;阿利特-硫铝酸钡钙水泥混凝土中水化产物的粒径分布均匀,界面粘结状况较好,结构较为致密。It was investigated that the relationship of water/cement ratio （W/C） and impermeability of -C2.75B1.25,A3S cement concrete by standard permeability test and pore structure analysis. Compared with Portland cement concrete, the impermeability of AliteC2.75B1.25,A3S cement concrete was much better at the same proportion and sam curing condition. The interface of cement and aggregate was more close-linked up each other of Alite-C2.75B1.25A3S cement concrete than that of Portland cement concrete. The structure of - C2.75B1.25,A3S cement concrete was much denser than that of Portland cement concrete.
