摘　　要：研究粉煤灰和钢渣作为胶结材单掺和双掺对透水混凝土强度的影响。结果发现：单掺粉煤灰和单掺钢渣时,随着掺量的增加,试样的早期强度均降低,但28天强度有所提高。当同时掺入粉煤灰和钢渣时（粉煤灰掺量为15%~20%,钢渣掺量为10%~15%）,透水混凝土的28天抗压强度可提高5 MPa左右,这说明粉煤灰和钢渣的双掺对透水混凝土强度的提高起到协同增强的效应。The effect of steelmaking slag and fly ash as multi additives on mechanical properties of permeable concrete was investigated. The results show that the 7d compressive strength of permeable concrete specimens with the single doped fly ash or steelmaking slag is decreased with increasing addition. While the 28d compressive strength of the specimens is increased. When the co-doped admixture is added with fly ash （15-20 wt.% ） and steelmaking slag （10-15 wt.%）, samples with good mechanical properties of the 28d specimens are obtained. The results indicate that multi binder with fly ash, steelmaking slag and cement has a significant impact on the compressive strength of permeable concrete.
