Abstract:
Reactive Powder Concrete (RPC) is a cementitious material consisting of cement, sand, silica fume, silica flour, admixture and water. The material was developed by Bouygues, the parent company of VSL, and is marketed under the brand name of Ductal. It is almost self placing, and has a compressive strength of 180 MPa. The durability properties are orders of magnitude better than current high performance concrete. RPC has been used worldwide for a number of structural applications, including several long span pedestrian bridges. However, the bridge over Shepherds Gully Creek will be the first bridge in the world to be constructed using RPC for normal highway traffic. The construction of this bridge is considered by the RTA as an evaluation trial of the materials, design procedures and constructability of RPC. At the time of writing this paper the precasting of the girders and the construction work on site had commenced. An update on the construction and test loading of the bridge will be available at this conference.
