| 摘 要： | 本文着重研究了粉煤灰对混凝土的收缩性能的影响。试验结果表明,掺粉煤灰混凝土的早期收缩略有增加,而28d龄期的收缩就已小于基准混凝土。粉煤灰以超量方式掺入对混凝土的后期收缩抑制作用更加明显。

| Abstract: | The paper focus on the investigation of effect of fly ash on shrinkage behavior of concrete. The rusults of experiment show that shrinkage of concrete containing fly ash at early age increase slightly while the shrinkage at 28d is smaller than that of criterion. Arrest effect of fly ash in ultra-high-volume on shrinkage of concrete at later age is more evident. |
