• Abstract:
  The objective of this research project was to identify the obstacles or impediments to successfully and reliably using HESC for structural bridge deck overlays on Oregon bridges and to develop the standards, specifications, processes, and practices necessary to using them on ODOT bridges. Rapid strength gain is a desired property for fast and efficient bridge deck overlay reconstruction. Three calcium sulfoaluminate (CSA) cement systems, an ASTM C 150 Type III ordinary portland cement (OPC), and a CSA-OPC blended system were evaluated in this research project for potential use as high early strength structural overlay materials for Oregon Department of Transportation (ODOT) concrete bridge decks. A high-performance concrete (HPC) mixture that is representative of ODOT bridge deck mixture designs from the early 2000s to present was also analyzed in this project. CSA cement systems performed satisfactorily when subjected to compressive strength tests, workability tests, curing tests, bond strength tests, early age cracking tests, freeze-thaw cracking tests, and thermal expansion tests when compared with HPC. Resistivity and formation factors of CSA concretes were measured and compared poorly to HPC resistivity and formation factors. While these values would normally suggest rapid rates of corrosion, the collected data is insufficient to conclusively indicate high corrosion rates since these tests were developed for OPC systems and may not be applicable to CSA systems. Additional work to elucidate the role of curing and conditioning of CSA systems is merited before definitive conclusions can be drawn regarding chloride-based corrosion in these systems.
