蒸养混凝土中矿物掺合料的激发效应研究

摘要

The excitation effects of comPound activator on three common mineral admixtures mineral slag,steel slag and fly ash are studied under the condition of steam curing. Using comPressive strength as the index, the results show that three of them have oPtimal dosage. The excitation effect of comPound activator on mineral slag is the best and the best dosage is 50%. The oPtimum dosage of comPound activator is 6% of mineral slag dosage. The excitation effect of comPound activator on fly ash is worse and on steel slag is the worst. ComPared with the standard curing under the same conditions,steam curing is more advantageous to the excitation effect of comPound activator.%研究了在蒸汽养护条件下，复合激发剂对常用的3种矿物掺合料矿粉、钢渣粉、粉煤灰的激发效应。结果表明：以抗压强度为指标，三者均存在最佳掺量，复合激发剂对矿粉的激发效应最好，其最佳掺量为50%，激发剂的最佳掺量为矿粉掺量的6%；复合激发剂对粉煤灰的激发效应次之，对钢渣的激发效应最差。在其他条件相同的情况下，与标准养护相比，蒸汽养护更有利于复合激发剂对矿粉的激发效应。
