Pre-tensioning is a technique used in the construction of roads and bridges to improve the strength and durability of concrete structures. It involves the following steps:
Via: Engineering Clarified
1. Tensioning Steel Strands: Before the concrete is poured, steel tendons are stretched along the length of a casting bed.

2. Pouring Concrete: Once the tendons are tensioned, concrete is poured around them. As the concrete sets, it adheres to the tensioned steel.

3. Cutting the Tendons: After the concrete has reached a sufficient strength, the tendons are cut. The tension is transferred from the tendons to the concrete through the bond, effectively compressing it.

The pre-tensioning process imparts compressive stress to the concrete, counteracting the tensile stresses that will occur when the structure is put into service. This enhances the load-carrying capacity of the structure and helps to control cracking, leading to more durable roads and bridges.
