What types of reinforcements are used in the process of prestressing?

Low relaxation cables, but I think the question was about the3 different types of presstress applications.
Spalling Reinforcement - stress behind the loaded area of the anchor blocks.
Equilibrium reinforcements - several anchorages, prestressing loads are applied in a sequential manner.
Bursting Reinforcements - stress trajectories are concave towards the line of action of load. 

Equilibrium Reinforcement, if it is building construction and bridged.

1. Spalling reinforcementSpalling stresses are established behind the loaded area of anchor blocks and this causes breaking away of surface concrete. These stresses are induced by strain incompatibility with Poisson’s effects or by the shape of stress trajectories.

2. Equilibrium reinforcementEquilibrium reinforcement is required where there are several anchorages in which prestressing loads are applied sequentially.

3. Bursting ReinforcementTensile stresses are induced during prestressing operation and the maximum bursting stress occurs where the stress trajectories are concave towards the line of action of the load. Reinforcement is needed to resist these lateral tensile forces.

Spalling, equilibrium & bursting reinforcement

Prestressed concrete is a method for overcoming concrete's natural weakness in tension.
Prestressing tendons (generally of high tensile steel cable or rods) 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.
The major types of reinforcements used in prestressing are:
1- Spalling Reinforcement: The spalling stresses leads to stress behind the loaded area of the anchor blocks.
2-Equilibrium reinforcements: these types of reinforcements are required where several anchorages exist where the prestressing loads are applied in a sequential manner.
3-Bursting Reinforcements: These kinds of stresses occur in cases where the stress trajectories are concave towards the line of action of load.
