摘　　要：对比研究了不同蒸养制度对固废基低碳胶凝材料抗压强度的影响,从而得到更适合低碳胶凝材料的蒸养制度。结果表明:固废基低碳胶凝材料蒸汽养护时,采用与诱导期基本相同的静停时间时可得到较好的早期强度,对于蒸养温度和蒸养时间,65℃蒸养12 h已经足以获得较为理想的早期强度,更长的蒸养温度和蒸养时间对于抗压强度的提升程度并不大。By designing different steam curing systems and comparing the changes law of compressive strength of low-carbon cementitious materials,optimum suitable steam curing system for low-carbon cementitious materials can be obtained.The results indicate that for solid waste based low-carbon cementitious materials,the early strength can be improved by using a waiting time the same as the induction period during steam curing.For steam curing temperature and steam curing time,65℃and 12 hours is sufficient to achieve ideal early strength,the compressive strength can not be improved significantly by longer steam curing time and higher steam curing temperature.
