Abstract:

An investigation was conducted to determine the effect of stress condition

and environmental exposure on corrosion of post-tensioned strands during ungrouted periods.

Exposures for periods of up to 4 weeks of stressed, as-received strand placed in tendon ducts

embedded in concrete and sealed with caps to represent normal practice and without any

trapped water did not result in any appreciable deterioration as evaluated by visual

appearance, standardized mechanical tensile testing, limited reverse bend testing, and

exploratory hydrogen pickup measurements. These results were observed at both an inland

and a seashore test site. There was, however, notable surface rusting and indications of

hydrogen pickup by the strand if water was trapped in the ducts or if the steel was exposed to

moderate salt spray precipitation and especially so with both factors concurrently. Evaluation

of significance of findings on current practice is presented.
