| 消泡剂和引气剂对混凝土性能影响的研究(51卷) |
| 英文标题 |
| Study on influence of defoaming agent and air-entraining agent on property of concrete |
| 摘要 |
| 消泡剂和引气剂对混凝土性能有重要影响。通过在聚羧酸系高性能减水剂中复配消泡剂和引气剂，探讨了两者用量对混凝土性能的影响。试验结果表明，随着消泡剂用量的增大，混凝土含气量和减水率减小，存在坍落度经时损失小的消泡剂的最佳用量范围；引气剂用量越大，混凝土含气量和减水率越大，当其用量在一定范围时，混凝土坍落度损失较小；混凝土的强度变化主要受加入消泡剂和引气剂后混凝土含气量的影响。 |
