摘　　要：本文通过测试钢渣粉的活性、安定性和钢渣砂的颗粒级配、含水率、含泥量、吸水率、安定性等基本性能,研究陈化龄期对钢渣砂安定性的影响。利用安定性合格、级配合理的钢渣砂、钢渣粉、矿渣粉、激发剂和工作性能、凝结时间调节组分,通过配合比设计制备出工作性能良好、凝结时间合理、力学性能优良的高性能砂浆,并对其体积稳定性能进行研究。The influence of ageing time on the stability of steel slag sand was studied by testing the activity,stability of steel slag powder and the basic properties of steel slag sand,such as particle size distribution,moisture content,mud content,water absorption and stability.High performance mortar with good working performance,reasonable setting time and excellent mechanical properties was designed and prepared by steel slag sand with qualified stability and reasonable gradation,steel slag powder,mineral slag powder,activator,and through adjusting the composition according to the working performance and setting time.In the meantime,the volumetric stability of the mortar was researched.
