Evaluation of Ultra-High Performance Concrete, Fiber Reinforced Self-Consolidating Concrete, and MALP Concrete for Prestressed Girder Repair

Ultra-high performance concrete (UHPC), fiber-reinforced self-consolidating concrete, and magnesium-alumino-liquid-phosphate (MALP) concrete all have significant potential for use in bridge repair in Oklahoma. The project described in this report examined the use of these materials in repairs of prestressed concrete girder continuity connections and beam end regions including both experimental testing and field implementation. Bond between the repair materials and conventional concrete and corrosion behavior were examined for each repair material. Twelve composite beam and continuity joint specimens were damaged and repaired using FR-SCC, MALP concrete, and UHPC. All repair materials restored capacity of the joints. Six girder specimens were loaded to failure in shear and repaired using FR-SCC, MALP concrete, and UHPC. Repaired specimens exhibited similar performance for all three repair materials and measured capacities exceeded those for the original beams in all cases. The soffit of the bridge deck cantilevers on the S.H. 3 bridge over Fulton Creek in Beaver County, Oklahoma was repaired using pneumatically placed MALP mortar and the repairs were monitored over time. Some difficulties were encountered in placing the material, but the repair exhibited good performance over time. The continuity joints on the U.S. 183/412 bridge over Wolf Creek in Fort Supply, Oklahoma were replaced using UHPC and load tests indicated the repair reestablished continuity.
