Prestressed concrete

Prestressing can be accomplished in three ways: pre-tensioned concrete, and bonded or unbonded post-tensioned concrete.

Prestressed concrete is a method for overcoming 's natural weakness in tension. It can be used to produce , or with a longer than is practical with ordinary . Prestressing tendons (generally of high tensile or rods) are used to provide a clamping load which produces a that offsets the that the concrete would otherwise experience due to a bending load. Traditional is based on the use of reinforcement bars, , inside poured .
