摘　　要：国家会议中心二期主体工程钢管柱采用C50高抛自密实混凝土,为满足混凝土具有良好的流动性、密实性的要求,通过优选原材料、确定胶凝材料、调整砂率,设计出满足力学性能要求,且流动性、均匀性、稳定性、填充性良好的混凝土。C50 high cast and self-compacting concrete was used for steel pipe column of phase Ⅱ main project of National Convention Center.In order to meet the requirements of good fluidity and compactness,by optimizing raw materials,determining cementitious materials,and adjusting the sand rate,concrete with good mechanical properties,fluidity,uniformity,stability and filling properties was designed.

关 键 词：自密实混凝土 配合比设计 流动性
