摘要
试验研究了赤泥-石膏复合激发剂对蒸养粉煤灰混凝土力学性能和长期性能的影响。结果表明,经激发剂改性后蒸养粉煤灰混凝土脱模抗压强度得到显著的提高,弹模、抗折、劈拉强度均得到不同程度的提高;干缩值得到降低,抗渗性能明显改善。
The effect of activating agent on mechanical properties and long-term properties of steam-cured fly ash concrete is studied by experiments in this paper.The results show that the addition of activating agent into steam-cured concrete blended 40% fly ash is effective in improvement of its compressive strength at demolding,as well as the elastic modulus,flexural strength,tensile-splitting strength,and also permeability and shrinkage of steam-cured fly ash concrete can be improved by the activating agent.
