养护制度对掺偏高岭土活性粉末混凝土强度的影响

Effects of Different Curing Systems on Compressive Strength of Metakaolin RPC

系统地进行了标准养护、湿砂养护、保温-标准养护、热水养护四种养护制度对掺偏高岭土活性粉末混凝土强度影响的试验研究。试验结果表明:相同配合比条件下,保温-标准养护混凝土抗压强度最高,湿砂养护次之,标准养护最低;热水养护能加速混凝土强度的发展,特别是前期强度,但后期强度增长有限。

This paper makes a systematic experimental study on the compressive strength of Metakaolin RPC influenced by different curing systems, i.e. standard curing, wet-sand curing, heat preservation-standard curing, and hot water curing. The experiment results show that, under the same mix ratio, heat curing guarantees the highest and quickest compressive strength, followed by wet-sand curing and standard curing; Hot water curing can speed up the strength development of Metakaolin RPC, especially in the initial stage, but the strength development is limited in the later stage.
