Reinforcements used in the process of prestressing: Especially in case of prestressing, we are using strands of Steel and it's called tendons.
Tendons are made of high strength Steel.
Three major types of reinforcements which are used in Prestressing:
Spalling R/f Equilibrium R/f Bursting R/f
Combination of reducing the structural thickness reduced conventional reinforcements quantities and fast construction often results in un prestressed structure.
