摘　　要：为了得到高强钢纤维混凝土最优配合比,采用探索试验研究分析高强混凝土配合比,利用正交试验方法研究原材料对高强混凝土的流动性和强度性能的影响规律,通过掺入不同体积率钢纤维得到了符合设计和施工要求的最优高强钢纤维混凝土配合比。结果表明:水胶比、高效减水剂、硅灰、钢纤维对高强混凝土抗压强度影响显著,粉煤灰对其强度影响不显著。研究成果可应用于超高强混凝土配合比设计及影响因素研究分析。In order to get the optimum proportion of high strength steel fiber concrete, exploration test is a- dopted in this paper to explore analysis of high strength concrete mix proportion, using orthogonal test method to research liquidity and strength performance influence law of raw materials on high-strength concrete. By adding different volume ratio of steel fiber, we can get the best proportion for high strength steel fiber rein- forced concrete in line with the design and construction requirements. The results show that water cement rati- o, high efficiency water reducing agent and silica fume have significantly influence on high strength concrete compressive strength, and fly ash has no significant effect on its strength. Research results can be used in high strength concrete fit ratio and influence factors analysis.
