[Abstract]:The purpose of this study is to optimize the mix ratio of steel fiber high strength concrete. In order to obtain the optimum mix ratio of steel fiber high strength concrete, the optimum mix ratio of steel fiber high strength concrete is analyzed by exploring test, and the orthogonal test method is adopted. In the design of steel fiber high strength concrete (SFHSC), the problems related to the mix ratio of raw materials are studied and analyzed. The optimum mix ratio of high strength steel fiber concrete is obtained by mixing steel fiber with different volume ratio in steel fiber concrete material. The results show that in the design of steel fiber high strength concrete, the optimum mix ratio of high strength steel fiber concrete is obtained according to the design and construction requirements. The addition of high efficiency water-reducing agent, water-binder ratio and steel fiber in the raw materials of concrete will have significant influence on the compressive strength of steel fiber high strength concrete. The optimum design of concrete mix ratio can enhance the strength of steel fiber high strength concrete. It is proved that the research results can be applied to the mix design of ultra-high strength concrete and the analysis of influencing factors.
