| 消泡劑和引氣劑對(duì)混凝土性能影響的研究(51卷) |
| 英文標(biāo)題 |
| Study on influence of defoaming agent and air-entraining agent on property of concrete |
| 摘要 |
| 消泡劑和引氣劑對(duì)混凝土性能有重要影響。通過(guò)在聚羧酸系高性能減水劑中復(fù)配消泡劑和引氣劑，探討了兩者用量對(duì)混凝土性能的影響。試驗(yàn)結(jié)果表明，隨著消泡劑用量的增大，混凝土含氣量和減水率減小，存在坍落度經(jīng)時(shí)損失小的消泡劑的最佳用量范圍；引氣劑用量越大，混凝土含氣量和減水率越大，當(dāng)其用量在一定范圍時(shí)，混凝土坍落度損失較??；混凝土的強(qiáng)度變化主要受加入消泡劑和引氣劑后混凝土含氣量的影響。 |
