浅谈自密实混凝土在路基施工中的应用和推广

Elementary Discussion on Application and Promotion of Self-compacting Concrete in Roadbed Construction

自密实混凝土流动性好,具有良好的施工性能和填充性能,而且骨料不离析,混凝土硬化后的力学性能和耐久性均良好。在介绍其施工工艺后,以杭瑞高速某路段为实例,先计算其初步配合比,然后经工作性调整,最终确定其基准配合比。

The self-compacting concrete fluidity is good and has the good construction performance and filling property, and its aggregate is not of segregation. The mechanical property and surface area of concrete after hardened are all good. The article introduces its construction technology. Taking a section of Hangrui Expressway as a practical case, the article calculates its preliminary mixing ratio and then defines its standard mixing ration after the working adjustment.
