Abstract

Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) has excellent mechanical properties and good durability. However, the embodied energy of UHPFRC is much higher than that of ordinary concrete due to the high usage of cement. In order to reduce the adverse environmental impact of utilizing UHPFRC, recycled rubber crumb is used as an additional component or as a replacement for fine aggregates. Cube specimens with two different mix design schemes were investigated during this study. The reduction of compressive strength was investigated. UHPFRC prisms were also cast and loaded in four point bending tests to check the reduction of flexural strength. The mixing procedure and temperature variation during the casting process was recorded. Some cube specimens were heat cured in hot water at 90 degree Celsius for forty-eight hours. Those cubes were tested following curing at around 7 days to obtain the early age strength, while other cubes are normally cured in water at around 20 degree Celsius with the prisms until 28 days.
