| 標(biāo)題 |
| 板式無砟軌道普通摻合料混凝土配制技術(shù)(51 卷) |
| 英文標(biāo)題 |
| Proportioning of concrete with common additive used for slab–type ballastless track |
| 摘要 |
| 無砟軌道構(gòu)件預(yù)制要求必須保證混凝土在帶模養(yǎng)護(hù)的條件下獲得較高的早期強(qiáng)度，選用粉煤灰、礦粉雙摻和早強(qiáng)高效減水劑，優(yōu)化板式無砟軌道鋼筋混凝土配合比設(shè)計(jì)，實(shí)現(xiàn)了每天一個(gè)循環(huán)的生產(chǎn)目標(biāo)，并且創(chuàng)造了良好的社會(huì)和經(jīng)濟(jì)效益。 |
