Ultra High Performance Concrete (UHPC) is a new cement-based material developed in the era of modern concrete technology. The present of fiber in UHPC composition is necessary to increase strengths and durability, which then lead to name the material as Ultra High Performance Fiber Reinforced Concrete (UHPFRC). However, the exact determination of UHPC and UHPFRC have challenges due to its very high compression strength. Some issues are the limited capability to purchase high load capacity testing machines, and the surface preparation requirement for cylinder specimens. In this study, three series of experimental programs were conducted to investigate the compressive strength of UHPC and UHPFRC using cylinder and cube specimens, and to determine its converting factors (ratio). The results show that the compressive strength relationships between specimens differ from those of conventional concrete. © 2015 The Authors. Published by Elsevier Ltd. Published by Elsevier Ltd.
