| 英文標(biāo)題 |
| Study on application of hybrid sand as concrete material used in engineering project of urban transit system |
| 摘要 |
| 通過試驗(yàn)對比，研究了人工混合砂、天然砂對軌道交通工程C35 P10防水混凝土性能的影響。結(jié)果表明:選取合適比例人工混合砂配制出的混凝土工作性能、早期抗壓強(qiáng)度、抗?jié)B性能和碳化性能均優(yōu)于天然中砂混凝土，后期抗壓強(qiáng)度和干縮性能稍遜于天然中砂混凝土。人工混合砂可替代天然 |
