Abstract:
The results of an extensive state-of-the-art survey are reported. Although the corrosion of prestressing steel is not a common problem, it has occasionally caused serious damages and failures. Corrosion of tendons is caused mostly improper construction techniques including handling, storage and shipping, and to a lesser degree, by improper design. High quality, dense, and impervious concrete or grout can furnish permanent corrosion protection in most environments to which a highway bridge is exposed, provided that certain requirements are satisfied. Recommended corrosion preventing measures of a civil engineering character are discussed in detail. More than 100 of the most important references are used.
