Abstract

In civil engineering structures involving prestressed concrete, the use of posttensioned systems is very common. Post-tensioning is achieved by passing steel cables into ducts previously cast into the concrete. When the concrete has set, the cables are tensioned with hydraulic jacks and then sealed into the duct by pumping in a slurry of cement and water, called grout. The grouting mixture, being alkaline in composition, protects the steel cable from corrosion.
