| 摘 要： | 配制了矿渣和粉煤灰含量为70%左右的绿色水泥,并用绿色水泥制备了绿色混凝土.用标准混凝土试验方法研究了绿色混凝土的抗压强度和抗折强度;用扫面电镜观察了绿色混凝土中的界面过渡区.结果表明:绿色混凝土的抗压强度和抗折强度均高于普通混凝土;绿色混凝土中的界面过渡区结构更加致密.界面过渡区结构更加致密是绿色混凝土强度高于普通混凝土的重要原因.

| Abstract: | Green cement that contained 70 percent of slag and fly ash was made.With the green cement used as cementitious material,green concrete was made.Compressive strength and bending strength of the green concrete was tested with standard ways.The interfacial transition zones(ITZ) in the green concrete was observed with SEM.The results showed that compressive strength and bending strength of the green concrete is higher than that of ordinary concrete.The ITZ in the green concrete is more compact than that in ordi... |
