4. Prestressed Concrete
Pre-stressed Concrete is a method for
overcoming concrete’s natural
weakness in tension .It can be used to
produce beams, floors or bridges with
a longer span than is practical with
ordinary reinforced concrete. It is
often used in commercial and
residential construction as a
foundation slab. Pre-stressing tendons
(generally of high strength steel
cable) are used to provide a clamping
load which produces a compressive
stress that balances the tensile stress
that the concrete compression
member would otherwise experience
due to a bending load.
5. Classification of Prestressed Concrete
External or internal pre-stressing
Linear or circular Pre-stressing
Pre-tensioning and post tensioning
Pre-tensioning system (fully
bonded Construction)
Post-tensioning System (end
anchored constructions)
Full pre-stressing or partial pre-
stressing
