| Abstract: | The mix proportion experiment of ultra high performance concrete without steel fibre was done by using right admixtures as reactive powder,orthogonal experiment and the closest packing experiment as methods.The optimal mix prop ortion of the ultra high performance concrete without steel fibre was obtained by testing the mechanical properties.And the influence of the incorporation method and the content of steel fiber on the performance of the ultra high performance concrete was studied.The results show that UHPC can also be obtained by using right admixtures and proper mix proportion design. |
