| 雙摻高性能混凝土配合比試驗(yàn)研究(49 卷) |
| 英文標(biāo)題 |
| Experimental study on mix proportion of high-performance concrete with admixtures of fly-ash and milled mineral powder |
| 摘要 |
| 雙摻粉煤灰和磨細(xì)礦粉可以改善混凝土耐久性能，對(duì)比研究了不同粉煤灰與磨細(xì)礦粉摻量混凝土的工作性、抗壓強(qiáng)度及耐久性能的影響。試驗(yàn)結(jié)果表明，隨著粉煤灰和礦粉總摻量的增大，混凝土的早期抗壓強(qiáng)度降低，抗碳化能力下降，但混凝土抗氯離子侵蝕的能力差異不大；總摻量相同時(shí) |
