The major types of reinforcements used in prestressing are:
We use Strands for single wires and Tendons for group of strands
we use tendons covered by anchors.
we use tendons with anchors
Spalling Reinforcement :
The spalling stresses leads to stress behind the loaded area of the anchor blocks. This results in the breaking off of the surface concrete. The most likely causes of such types of stresses are Poisson`s effects strain interoperability or by the stress trajectory shapes.

Equilibrium reinforcements: These types of reinforcements are required where several anchorages exist where the prestressing loads are applied in a sequential manner.
