    Abstract

    This dissertation aims to explain the results of investigation into the behaviour of ultra-high performance fibre reinforced concrete (UHPFRC) subject to bending and compression. Knowledge of these mechanical properties is fundamental in allowing design of elements incorporating UHPFRC. Investigation into the varying effects of curing regimes was intended to further insight into the ideal and most economic method for dealing with UHPFRC, with the acceleration of construction technology firmly in mind. Replacement cementitious materials were also tested, primarily as an exercise into environmentally stable replacements in technologically advanced concretes. Specimens were prepared using differing percentages of cement replacement, then cured for a period of 28 days in three separate ways; no curing, water based curing and thermal curing. Results indicated that while thermal curing may be used in industry to achieve high early age strength, it suffered slightly at age compared to traditional submergence curing. As to be expected, no curing regime produced the lowest results, both in compression and under bending, however there was surprising overlap. In terms of cementitious replacement, the straight cement mixes fared best although the percentage difference of the other mixes was not altogether large.
