Abstract

Ultra-High Performance Fiber Concrete (UHPFC) is one of the breakthroughs in the 21st century in the field of concrete technology where this composite material providing an important improvement in strength, workability, ductility and durability when compared with normal concrete. This paper discusses the influence of different curing conditions on the mechanical properties of UHPFC and the bonding between UHPFC and bar of 12 mm in diameter. An experimental program was performed to study the mechanical properties of UHPFC which were cured under six different curing conditions. Test results indicated that steam and boil curing methods showed a promising performance particularly at early age of curing compared to other type of curing. The results of pull out test showed that the failure was in bar (bar rapture failure) in all type of curing regimes.
