Abstract:The main objectives of this research project were to: (1) Develop mix designs and examine the fresh and hardened properties of self-consolidating concrete (SCC) and fiber-reinforced SCC (FR-SCC) using locally-available materials, steel and synthetic macro-fibers, and varying percentages of a Type-K shrinkage-compensating cement; (2) Investigate compatibility and bond strength of FR-SCC as a repair material and select mixes that yield the best performance for the subsequent phase of the research project, namely full-scale testing; (3) Evaluate the structural performance of full-scale repaired beams using the FR-SCC mixes developed previously; and (4) Transition the technology from the laboratory to the field with an implementation project involving the repair of in-service bridge girders followed by removal and testing of the girders to failure.
