摘　　要：将锰铁高炉废渣研磨后过0．08 mm筛,分别代替15％、30％和50％水泥,制作成水泥砂浆试件并测试试件强度。试验结果表明,锰渣掺量在0-30％范围内,虽然对试件的早期强度略有影响,但后期强度基本不变,锰渣的合理掺量应在30％左右。烟气灰掺量为15％时,可提高试件的力学性能;当掺量在30％时,会影响试件后期强度。锰渣或烟气灰的掺量高达50％时,均会使试件力学性能大大下降。Screening O. 08ram after grounding FeMn blast furnace slag, the material is used instead of 15%, 30% and 50% cement, cement slurry test is made to test its strength. It shows that, when the Mn slag mix in the range of 0 ～30%, it has a little impact on the preliminary strength, but later the strength stabilizes. The reasonable mix should be controlled around 30%. When the ash mix in 15%, it can promote test performance, when it reaches 30%, it will influence latter strength, when the Mn slag or ash mix reaches 50%, it will decrease test dynamical performance.
