Corrosion Characteristics of Post-Tensioning Strands in Ungrouted Ducts, Summary
To prevent corrosion of post-tensioning strands, FDOT construction specifications currently require post-tensioning ducts to be grouted within seven calendar days of strand installation. This period challenges construction schedules on large projects and may be unnecessarily brief in mild service environments. A literature review indicated that the seven-day limit is a common specification among transportation agencies, but some allow periods up to 40 days for mild environmental conditions.
