With advances in concrete technology, ultra high performance concrete (UHPC) has become a new focus for researchers and the concrete industry. UHPC is characterized by high compressive strength and excellent durability properties resulting in lighter structures and longer life. Different approaches have been adopted by researchers in achieving ultra high strength and associated other improved performances. As a result, several types of UHPC are available today such as Reactive Powder Concrete (RPC), Densifi ed with Small Particles (DSP) concrete, Special Industrial Concrete (BSI), Macro Defect Free (MDF) concrete, Self Compacting Concrete (SCC), Compact Reinforced Concrete (CRC) etc. A general description and their range of applications are reported here. In addition, Research at RMIT on Modifi ed Reactive Powder Concrete and very high strength (VHSC) and ultra high strength concrete (UHSC) is briefly outlined.
