摘　　要：通过对比试验和正交试验,研究钢渣粉复合掺合料对混凝土抗氯离子渗透能力的改善情况。试验结果表明,钢渣粉复合掺合料能够明显提高混凝土的抗氯离子渗透能力,并且复合掺合料掺量(即取代水泥量)从30%增加到50%,混凝土的抗氯离子渗透能力逐渐提高;掺合料比例、水胶比和取代水泥量是影响混凝土抗氯离子渗透能力的主要因素。Through comparative experiment and orthogonal test,the improvement on the permeability of concrete resistance to chloride ion by steel slag powder admixture was studied.The experimental results showed that the permeability of concrete resistance to chloride ion could be remarkably improved by the admixture,and with the admixture volume（cement replacement volume） increased from 30% to 50%,the permeability improved gradually.It was the admixture proportion,water-cement ratio and cement replacement volume that mainly affected the permeability of concrete resistance to chloride ion.
