摘　　要：将矿渣和粉煤灰分别等掺量替代水泥,制备了矿渣混凝土和粉煤灰混凝土立方体试件,检测了不同龄期的混凝土抗压强度,探讨了其力学性能变化规律,试验结果表明:在等量替代水泥的情况下,矿渣混凝土比粉煤灰混凝土的抗压强度大;粉煤灰混凝土的后期强度比普通混凝土大;矿渣、粉煤灰混凝土随着掺量的增大,其强度均不断降低。The paper replaces the cement with the slag and fly ash,makes the slag concrete and fly ash concrete cubic specimens,tests the concrete compression with various ages,explores their laws of dynamic performance changes,and proves by the result that the slag concrete has higher compression than the fly ash concrete under the equal volume to replace the cement,the compression of the fly ash concrete in the later period is larger than the common concrete,the compression is gradually reduced with the increasing mixture of the slag and fly ash concretes.
