摘　　要：采用大掺量矿物掺合料配制C30~C60自密实混凝土，并对自密实混凝土的工作性能、强度及抗氯离子渗透性能进行研究。结果表明，增加胶凝材料用量可以改善混凝土的自密实性能，采用大掺量矿物掺合料替代水泥保证混凝土粉体总量，是配制中低强度自密实混凝土的方法之一；大掺量矿物掺合料自密实混凝土的抗压强度和抗氯离子渗透性能随龄期的增长不断提高，大矿物掺合料自密实混凝土的抗压强度和抗氯离子渗透性能评价应以56d龄期为准。C30~C60 self-compacting concrete （SCC） is made by a high volume of mineral admixtures. The workabili-ty, strength and the penetration resistance of chloride ions performance of SCC are investigated. The results show that in-creasing the proportion of binding material can improve the self compacting performance of concrete, and using large amount of mineral admixture as substitution of cement is a way of making mid-low strength SCC. The compressive strength and penetration resistance of chloride ions performance of SCC with a large proportion of mineral admixtures are improved continually with the increase of curing period, and should be evaluated by the age of 56d.
