Influence of Curing Regime on the Ductility of Ultra-High Performance Fiber Reinforced Concrete (UHPFRC)
Ultra-High Performance Fiber Reinforced Concrete (UHPFRC), characterized by its outstanding mechanical and ductile performance, have received significant attention recently in the construction. In this paper, curing of UHPFRC cubes and prisms at 20°C and 90°C has been investigated to quantify the differences in both mechanical and ductile performance within the age of 91 days. The results shows that specimens cured at 20°C gives approximately 20%, 10% and 15% lower performance in compressive strength, flexural strength and fracture energy than specimens cured at 90°C, respectively. However, the 20°C-cured specimens not only achieve above 120MPa, 20MPa and 18kJ/mm2 in compressive strength, flexural strength and fracture energy, but also show advantage in maintaining flexural resistance in the ductile deformation. The results of the research demonstrate the feasibility of in-situ concrete placement and construction of UHPFRC.
