چکیده
This study investigates the mechanical behavior and fresh properties of basalt fiber-reinforced Self-Compacting Concrete (SCC) using Response Surface Methodology (RSM) with a Box-Behnken design at three levels to optimize variable interactions. Twelve SCC mixtures were prepared, varying basalt fiber contents (0, 0.5, 1.25, 2 vol.%) and nanosilica dosages (6, 8, 10 kg/m³). Fresh properties were evaluated via Slump Flow, V-funnel, L-box, U-box, and J-ring tests, yielding slump flows of 650–800 mm and confirming workability. Hardened properties compressive strength, tensile strength, elastic modulus, and permeability were assessed after 28 days of curing. Nanosilica and basalt fibers significantly enhanced mechanical performance and reduced permeability. The optimal mix (10 kg/m³ nanosilica, 2 vol.% basalt fibers) achieved 61.8 MPa compressive strength, 56.85 MPa tensile strength, 60.88 GPa elastic modulus, and 4.7 mm permeability improvements of 27%, 33.76%, 16%, and 31.88% over controls. ANOVA validated second-order models (R² > 0.97) for predictive accuracy. Sensitivity analysis identified nanosilica dosage as key for compressive strength and water-to-cement ratio for permeability. Monte Carlo simulations provided 95% confidence intervals, and benchmarking against empirical models confirmed RSM's superiority. This research ensures dimensional consistency and offers practical guidance for scalable, sustainable SCC designs, minimizing experiments and costs.
