What is Pre Vs Post Tensioning about?

Prestressing in concrete can be achieved through Pre-tensioning, where tendons are tensioned before casting, and Post-tensioning, where tendons are tensioned after the concrete hardens. Pre-tensioning is suitable for short spans and is done in precast factories, while Post-tensioning is used for longer spans and performed on-site. Pre-tensioning is more economical for mass production, whereas Post-tensioning involves higher costs due to additional components like ducts and jacks.
