紫源水电站自密实混凝土配合比设计试验

Ziyuan Hydropower Station self-compacting concrete mix proportion design test

自密实混凝土(SCC)是指在浇筑过程中无需施加任何振捣,仅依靠混凝土自重就能完全填充至模板内任何角落和钢筋间隙的混凝土。本文在分析了铅山县紫源水电站现场施工场地有限、工期紧的原因后,提出了通过试验确定工程混凝土所需配合比的措施,以保证紫源水电站大坝主体工程正常实施,早日发挥工程效益。

Self-compacting concrete（ SCC） refers to concrete which does not need any vibration in the pouring process,and can be completely filled to any corners and reinforced gaps in the template due to concrete self-weight. In the paper,reasons of limited site construction field and short construction duration in Qianshan County Ziyuan Hydropower Station are analyzed. Measures of determining mix proportion necessary for project concrete through test are proposed,thereby ensuring the normal construction of dam main project in Ziyuan Hydropower Station,and exerting project benefits as early as possible.
