摘　　要：用云南昆钢工业废渣综合利用开发有限公司生产的钢渣粉,与矿渣粉和粉煤灰复掺,制备C30混凝土,对混凝土的抗冻性、抗渗性、抗碳化性和收缩性等耐久性能进行了分析,结果表明,随着时间的延长,掺入钢渣粉混凝土的抗碳化性能较好,总收缩率较大,基准混凝土和掺钢渣粉混凝土都具有较好的抗冻性和抗渗性。通过SEM分析了不同龄期水化产物的表面形貌。The concrete of C30 was prepared with the steel slag powders that were prepared by Yunnan Kunming Steel Industry Waste Residue Comprehensive Utilization and Development Company, mixed slag powders and fly ash. The durable property of concrete such as the frost resistance, anti-permeability, carbonation resistance and shrinkage property was analyzed. The results showed that the carbonation resistance performance of concrete mixed the steel slag powders is good, the total shrinkage is larger. With and without steel slag powder concrete have good frost resistance and permeability resistance. The surface morphology of different age hydration products was analyzed by SEM.
