摘要 以工业辊磨生产的镍铁渣粉产品为研究对象,对其基本性能进行检测,分别以30%和40%等质量替代水泥,研究其用作矿物掺合料对混凝土力学性能、工作性能和耐久性等性能的影响,并与S95级矿粉和Ⅱ级粉煤灰进行比较。研究结果表明,掺入镍铁渣粉的混凝土力学性能和坍落度较矿粉和粉煤灰混凝土略差;凝结时间与矿粉比较接近,但比Ⅱ级粉煤灰混凝土凝结时间短;在适当掺量时,镍铁渣粉混凝土的抗冻性和抗碳化性与矿粉和Ⅱ级粉煤灰相当。

Abstract: The basic properties of the ferronickel slag powder produced by roller mill have been tested. The influence of ferronickel slag powder as the concrete admixture to the mechanical performance, work performance and durability of concrete has been investigated based on 30% and 40% mixed proportions, and compared with grade S95 slag powder and grade II fly ash. Results show that the slump and mechanical performance of concrete using ferronickel slag powder as the admixture are slightly worse than the slag powder and fly ash concrete, with nearly the same setting time as slag powder concrete but less setting time than grade II fly ash concrete. Based on appropriate mixed proportions, the frost resistance and carbonization resistance of ferronickel slag powder concrete are equivalent to those of slag powder and grade II fly ash concrete.
Key words:   ferronickel slag powder    mineral admixture    radioactivity    strength    durability
