Pre-tensioning concrete
Pre-tensioning concrete involves applying tension to steel tendons before the concrete is poured and set. This technique enhances the strength and durability of concrete structures by counteracting tensile stresses that the concrete might encounter during use.

Pre-tensioning is accomplished by stressing wires or strands, called tendons, to predetermined amount by stretching them between two anchorages prior to placing concrete as shown in fig.1. The concrete is then placed and tendons become bonded to concrete throughout their length.

It is a type of concrete in which high-strength tendons placed in tension regions of the cross-section are stressed during the construction of the el…
Prestressed concrete - Wikipedia
Pre-tensioned concrete is a variant of prestressed concrete where the tendons are tensioned prior to the concrete being cast. The concrete bonds to the tendons as it cures, following which the end-anchoring of the tendons is released, and the tendon tension forces are transferred to the concrete as compression by static friction.
