摘　　要：为了研究钢渣混凝土中钢渣掺量对混凝土试块抗冻以及抗渗性能的影响,通过试验得到了不同钢渣掺量下钢渣混凝土的抗渗压力和冻融循环下强度比变化的试验测试结果。试验结果表明,水灰比相同并掺加一定外加剂下,混凝土的抗渗性与钢渣掺入量有关,随着钢渣掺量的增加混凝土含气量有所增加,含气量的增加使得混凝土的抗渗和抗冻性能有了明显提高,但抗压强度有一定程度的降低。本文研究的成果,可为钢渣混凝土抗冻以及抗渗性能的研究提供一定的参考。In order to study the influence of steel slag content in steel slag concrete on the frost resistance and impermeability of concrete blocks,the test results of impermeability pressure and strength ratio of steel slag concrete under different steel slag content were obtained through experiments.The test results show that the impermeability of concrete is related to the amount of steel slag added with the same water cement ratio and certain additives.With the increase of steel slag content,the air content of concrete increases.The increase of air content makes the impermeability and frost resistance of concrete improve obviously,but the compressive strength decreases to a certain extent.The research results can provide some reference value for the study of frost resistance and impermeability of steel slag concrete in this paper.
