Abstract

The effect of steel, and hybrid fiber contents are studied on the mechanical properties of the new generation Ultra High Performance Concrete (UHPC) produced by available local materials. According to the curing condition and fiber content; the compressive strength, flexural strength, and tensile strength reach 175 MPa, 21.35 MPa, and 12.5 MPa respectively. Based on the data of testing, an optimized concrete mix proportion compressive strength of more than 150 MPa is proposed.
