Strength Prediction of Self-Consolidating Concrete Containing Steel Fibre with Different Fibre Aspect Ratio

The present study presents the effects of steel fibre aspect ratio on fresh and strength properties self-consolidating concrete (SCC). Steel having three different ratios (50, 65 80) with inclusion rate 0.2%, 0.4%, 0.6%, 0.8%, 1.0% was considered, SCC were investigated. Central composite design (CCD) RSM modeling considered to propose a regression model predict 28-day compressive fibre-reinforced (SFSCC) incorporating supplementary cementitious materials (SCMs). 94 data sets retrieved from various literatures experimental set (SCC SFSCC) this have been used develop model. Further, cement content, powder water binder ratio, coarse aggregate fine as basic variables model, their influence prioritized using analysis variance (ANOVA) Pareto chart. findings compared results sets, comparisons confirm that proposed are very realistic precise SFSCC ratio.
