| Description |
Prestressing cables are widely used in huge constructions like buildings and bridges. Corrosion of
prestressing steel is more dangerous than the corrosion of reinforcing steel in concrete. Stress
corrosion is propagated due to corrosion initiation in prestressing steel under stressed condition.
Corrosion resistance of the prestressing steel depends upon the grout material. In this investigation
three types of grout materials namely cement grout with non-shrinking admixture, polyurethane foam
and epoxy grout were assessed for its suitability within the prestressing cable duct. The performance of
grout materials to protect against prestressing steel corrosion was evaluated by different
electrochemical techniques such as OCP measurements, anodic polarisation test and impressed voltage
technique. The mechanical property of the different grout materials were test at room and elevated
temperature. Among the three grouts, epoxy based grout system showed better corrosion resistance
properties.
