| Abstract: | In Beijing-Tianjin inter-municipal Railway engineering double-track precast box girders are constructed by high performance concrete to satisfy the long-time use of structure as one hundred years. Based on the experiments of 3# girders in Beijing-Tianjin inter-municipal Railway engineering,the ration design of high performance concrete is introduced from the following factors:the quality control of concrete raw material,the optimized ratio and the related tests before construction. |
