崇启大桥C35承台混凝土配合比设计与优化

摘要

以崇启大桥承台混凝土施工为依托，结合大体积混凝土质量控制关键点，提出配合比设计方案，通过对混凝土的工作性能、力学性能及各项耐久性性能的分析和研究，最终得到配合比优化方案。%For the construction of platform concrete of Chongqi bridge and combined with key points of quality control,the mix designs were proposed. The finally mix proportion was obtained through the study of work performace,mechanical properties and durability per-formance.
