摘要

•Response surface methodology is utilized to determine the optimal composition of UHPC.•Quadratic polynomial model is established and the results show good fitting and high predication accuracy for strength.•Experimental verification confirmed the results of response surface methodology optimization.•UFFA and MK reduces the overall cost and carbon emissions.•Incorporation of UFFA improves compressive strength of concrete significantly.
