| 高摻量粉煤灰對(duì)高性能混凝土體積穩(wěn)定性及耐久性的影響(50 卷) |
| 英文標(biāo)題 |
| Influence of large quantity of flyash on volume stability and durability of high-performance concrete |
| 摘要 |
| 研究了粉煤灰在較高摻量時(shí)對(duì)混凝土收縮性能、抗碳化性能、抗氯離子滲透性能與抗凍性能的影響。試驗(yàn)發(fā)現(xiàn)：粉煤灰摻量在0～25 %范圍內(nèi), 混凝土收縮隨著粉煤灰摻量的增加而減少，但粉煤灰摻量超過(guò)20%后，收縮減少的幅度變??；當(dāng)粉煤灰摻量高于30%時(shí)，混凝土的碳化速度迅速增加， |
