摘　　要：研究了不同碱当量、环境温度、硅酸盐水泥掺和量、粉煤灰掺和量对碱矿渣混凝土早期强度的影响,实验结果表明,添加低温添加剂后,8%碱当量的配合比能满足10℃、1d养护时间后混凝土的早期强度,并能以添加适量粉煤灰的形式改善工作性能。This paper studies the effect of different alkali equivalent, environment temperature, Portland cement dosage, coal ash dosage on the early strength of alkali-activated slag concrete. The experimental results show that after low temperature additives, 8% alkali equivalent mixing proportion can satisfy the early strength with 1 day curing time in 10℃, and the work performance can be improved by adding appropriate coal ash.
