Manufacturing of Sustainable Ultra-High-Performance Concrete Using Response Surface Methods

Abstract

3 of locally sourced limestone powder in the mixture with a w/b ratio equal to 0.198 and a 48hr-90°C curing regime can be considered the optimal amount to secure the greatest modeling compressive strength (169.10 MPa at 7 days and 181.71 MPa at 28 days), fulfilling the limit values of spread flow (220 mm) with the increasing percentage ratio of 67% and 49% at 7-days and 28-days ages under 90°C heat curing when the w/b equals 0.198.
