Cost Effectiveness of HDPE Sheathing For Post-Tensioned Prestressed Concrete Structures Over Galvanised Metallic Ducts – A Study
IntroductionPrestressing duct is one of the vital elements of total prestressing system.
The main functions of the duct are:
- To create cavity / void in the concrete, along the profile of the prestressing cable so that the cable can be threaded into it after the concrete gets hardened.
- To provide the protection against the corrosion to the prestressing steel.
