将选厂尾砂、炉渣、水泥和水按不同比例制成试块，测试其７天、２８天和９０天龄期的单轴抗压强度，根据抗压强度值判断在胶结充填中用工业炉渣替代水泥的可行性。试验结果表明，当炉渣替代水泥量超过３０％时，试块的各龄期单轴抗压强度随着炉渣量的增加而提高，并且，炉渣掺量越高，对试块的后期强度更为有利。用炉渣替代７０％水泥的试块７天、２８天和９０天龄期单轴抗压强度比不掺炉渣同龄期单轴抗压强度分别提高２０．７％、８８．６％和８２．０％。 The tailings, slag, cement and water of the plant were made into test blocks in different proportions to test their uniaxial compressive strength at 7 days, 28 days and 90 days. According to the compressive strength value, Feasibility of slag replacement cement. The test results show that the uniaxial compressive strength increases with the increase of slag amount when the slag replacement cement content exceeds 30%, and the higher the slag content is, the later strength of the test piece is more favorable. The uniaxial compressive strength at 7 days, 28 days and 90 days of testing with slag instead of 70% cement increased by 20.7%, 88.6% and 82.0% respectively %.
