摘　　要：本文研究了高掺量矿物掺合料对水泥基材料固化氯离子能力的影响,并借助XRD、DTG等进行了分析,研究结果表明:在水泥掺量为20%情况下,随着矿粉和Na Cl的掺量的增加,提高了水泥基材料的强度。高掺量的矿粉促进了水泥基材料中的F盐和镁铝水滑石的生成提高了其对氯离子的固化能力,增加浆体的水灰比对氯离子的固化也起到了促进作用。The capacity of cement-based materials binding chloride ions with a large number of supplementary cementitious materials（SCMs） and analysis of it by using XRD and DTG are studied.The experimental result shows that in the case of the cement content 20%,the compressive strength of the cement-based materials has been increased by adding the amount of slags and sodium chlorid.Moreover,it will contribute to the resistance to chloride ions because of high addition of the slags（SCMs） producing more Friedel salt and Mg-Al hydrotalcite as well as improving the water cement ratio.
