摘　　要：以不同龄期的抗压强度为控制指标,研究了蒸养制度对粉煤灰混凝土强度的影响。试验结果表明对粉煤灰混凝土而言,蒸养制度预养时间2 h、升温时间2 h、恒温温度60℃左右、恒温时间8 h以及降温时间1 h是比较合理的。By testing compressive strength at different ages, the influence of steam-curing system on the strength of concrete containing fly ash was studied.The experimental results indicate that the steam-curing system with procuring time for 2 h, heating-up time for 2 h, maximmn temperature for 60 ℃ ,temperature holding time for 8 h and cooling time for lh is suitable on the concrete containing fly ash.

关 键 词：蒸养 粉煤灰 混凝土 抗压强度
