Final Evaluation of Corrosion Protection for Bonded Internal Tendons in Precast Segmental Construction
In 1993, aware of unfortunate experiences in Europe in early non-epoxy segmental joints, Research Project 0-1264 was started with the main purpose of investigating the corrosion protection of internal tendons at segmental joints. This testing program was transferred to Project 0-1405 for long-term testing. Half of the thirty-eight laboratory specimens were autopsied after around four and one-half years of high aggressive exposure and the preliminary conclusions were reported in 1999. The variables included were joint type (dry or epoxy), duct type (galvanized steel or plastic), grout type (3 grouts with differing additives) and level of joint compression (3 different levels). This report documents the final results, after the second half of the specimens were autopsied with over eight years of very aggressive exposure.
