Abstract:This study uses response surface methodology and central composite design to optimize the UHPC mixture. The optimized UHPC mixture with 2% steel fiber by volume achieves a 22,113 psi (153 MPa) compressive strength. The study undertakes a comprehensive experimental program to evaluate compressive strength, freeze-thaw durability, surface resistivity, and autogenous and drying shrinkage on the non-proprietary mix using available test standards.
