摘　　要：研究了气淬钢渣活性、制备钢渣水泥的方案及不同方案下制备的掺气淬钢渣水泥的物理性能及水化机理。结果表明,气淬钢渣活性指数高于普通钢渣,制备掺气淬钢渣水泥适宜采用加入激发剂或复掺水淬高炉矿渣,在激发剂作用下,气淬钢渣掺量达到50%时,其水泥强度满足P.SS32.5级水泥的要求,而普通钢渣在掺量为50%时,强度已达不到水泥的强度要求;而在复掺水淬高炉渣和气淬钢渣作用下,气淬钢渣掺量达到40%时,其水泥强度满足P.SS32.5级水泥的要求,而普通钢渣水泥强度已达不到要求;气淬钢渣用于生产高掺量、高强度等级的水泥是可行的。The activity of gas quenching steel slag, preparation methods of steel slag cement and the physical properties and hydration mechanism of gas quenching steel slag cement prepared in different ways were studied. The results showed that the activity index of gas quenching steel slag was higher than that of ordiary steel slag. It was suitable to produce gas quenching steel slag cement by adding activator or water quenching blast furnace slag. Under the effect of the activator, the strength of cement could reach the requirement of P. SS32.5 cement when gas quenching steel slag content was up to 50%. The strength of steel slag cement could not reach the requirements when the content of the ordinary steel slag was 50%. Under the effect of water quenching blast furnace slag and gas quenching steel slag, the strength of cement could reach the requirement of P·SS32.5 cement when gas quenching steel slag content was up to 40%, but the strength of the ordinary steel slag cement could not reach the requirements. So it was feasible to prepare high addition and high-grade cement with gas quenching steel slag.
