Abstract: An experimental study on the flexural performance of Ultra-high performance concrete (UHPC) without thermal curing was carried out via four-point bending tests. Based on the test results, discussions on how to effectively evaluate the flexural performance of UHPC were presented. The four-point bending test results indicated that UHPC possesses not only high flexural strength, but also high flexural toughness and ductility. ASTM C1609 and JSCE-SF4 were
found to be suitable for the characterization of the flexural performances. However, they have certain limitations to evaluate the flexural toughness of UHPC at deformation larger than 1/150 of spanˈat which UHPC still has excellent loading capacity. It was found that the mid-span deflection extended from 1/150 to 1/75 of span can be more accurate to characterize the flexural
performance of UHPC.
