What reinforcements are used in the process of prestressing?

The major types of reinforcements used in prestressing are:

• 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.

• Bursting Reinforcements: These kinds of stresses occur in cases where the stress trajectories are concave towards the line of action of load. In order to reduce such stresses reinforcements in the form of bursting is required

We use Strands for single wires and Tendons for group of strands

we use tendons covered by anchors.
