摘要：在NaOH及水玻璃（WG）两种碱激发剂下，研究了粉煤灰及炉渣对碱激发镍渣-粉煤灰-炉渣胶凝材料（ANC-FI）流动度及强度的影响，并通过XRD和IR揭示其机理。结果表明，当粉煤灰及炉渣总掺量为30%（等质量取代镍渣）时，随着炉渣掺量的增加（即粉煤灰掺量降低），ANC-FI的标准稠度用水量增加，凝结时间延长，砂浆流动度降低；ANC-FI抗折强度和抗压强度均随着炉渣掺量的增加呈先增大后减小的趋势，最佳掺量为粉煤灰和炉渣各取代15%的镍渣。 Abstract: The effects of fly ash and incineration slag on the fluidity and strength of alkali-activated nickel slag-fly ash-incineration slag cementitious material ( ANC-FI) with NaOH or water glass (WG) as activators were studied, and the mechanism was revealed by XRD and IR. The results show that when the nickel slag is replaced by 30% of fly ash and incineration slag, with the increase of the incineration slag content (i.e., the amount of fly ash is reduced), the standard consistency water consumption of ANC-FI is increased, the setting time is prolonged and the fluidity of ANC-FI is reduced. The flexural strength and compressive strength of ANC-FI increase first and then decrease with the increase of incineration slag content, and when the nickel slag is replaced by 15% fly ash and 15% incineration slag respectively, the optimum ANC-FI can be obtained.
