COMPOSITION OF REACTIVE POWDER CONCRETES

Development of an ultra-high strength ductile concrete designated RPC (Reactive Powder Concrete), was made possible by the application of a certain number of basic principles relating to the composition, mixing and post-set heat curing of the concrete. RPC 200, which can be used under job site conditions similar to those for conventional high perfo rmance concretes, can be used in the construction of prestressed struc tures incorporating no passive reinforcement. RPC800 is suitable for p recasting, and can achieve compressive strength values exceeding 600MP a. A value of 810MPa has been obtained with a mixture incorporating st eel aggregate.
