CORROSION AND CORROSION PROTECTION OF TENDONS IN PRESTRESSED CONCRETE BRIDGES

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 BY 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. /AUTHOR/
