摘要
通过对13组39个150×150×150高强混凝土及钢纤维高强混凝土试件的试验,分析了钢纤维体积率和混凝土强度等级对钢纤维高强混凝土抗压强度的影响,提出了钢纤维高强混凝土抗压强度的回归计算公式。结果表明:钢纤维体积率和混凝土强度等级对钢纤维高强混凝土的抗压强度均有一定的影响;试验值与回归公式的计算值吻合较好。
Through the experimental research on the 39 specimens of high-strength concrete and steel fiber reinforced high-strength concrete with the size of 150 mm×150 mm×150 mm,the influence of the steel fiber volume and strength grade on the compressive of the steel fiber reinforced concrete is analysed.The regression formula for the compressive strength of the steel fiber reinforced concrete is put forward.The results show that compressive strength of the steel fiber reinforced concrete is influenced by the steel fiber volume and the strength grade of concrete.Good agreement between the theoretical values and the test results is available.
