| Abstract: | The influence of additional amount, ratio of water to cementing material, sand percentage and air content of concrete on the elastic modulus and 10 d strength of C50 concrete beam was investigated. The mix proportion of high-performance concrete beam was obtained, which is satisfied with the requirement of design and construction and will give a guide to the mix proportion design of railway construction. |
