The current systematic study investigates properties of hybrid fiber reinforced self compacting concrete (HyFRSCC) with crimped steel fibers (CSF) and polypropylene fibers (PPF) along with class F fly ash (FA) and colloidal nano silica (CNS). Optimization of HyFRC mix is conducted using L₁₆ Taguchi Orthogonal Array where additive has four levels. Combination of 10% FA, 0.4% CNS, 1.25% CSF and 0.167% PPF found to be optimal recommendation. Multiple linear regression analysis predicts equations of tensile strength as the function of cylinder compressive strength, for combination of FA, CNS, CSF and PPF. A good correlation between tested and predicted values is obtained.

当前的系统研究研究了具有卷曲钢纤维（CSF）和聚丙烯纤维（PPF）以及F级粉煤灰（FA）和胶体纳米二氧化硅（CNS）的混合纤维增强自密实混凝土（HyFRSCC）的性能。使用L ₁₆ Taguchi正交阵列对HyFRC混合物进行优化，其中添加剂有四个含量。推荐使用10％FA，0.4％CNS，1.25％CSF和0.167％PPF的组合。多元线性回归分析预测了FA，CNS，CSF和PPF组合时抗拉强度方程作为圆柱体抗压强度的函数。获得了测试值和预测值之间的良好相关性。
