Prestressed Ultra High Performance Concrete Beams From Local Materials

Large-scale prestressed ultra high performance concrete (UHPC) girders were cast and tested under four-point bending. All materials, excluding the steel fibres, were obtained from local suppliers in the state of New Mexico, USA in order to provide a more economically feasible UHPC compared to commercially available products. Two beams were tested to investigate their structural behaviour, the contribution of steel fibres, and the elimination of all mild steel reinforcement (including shear reinforcement). The results of these tests will aid the development of design procedures and further the implementation of UHPC into infrastructure.
