Prestressed concrete construction Prestressed concrete Prestressed concrete is a method for overcoming concrete’s natural weakness in tension. It can be used to produce beams‚ floors or bridges with a longer span than is practical with ordinary reinforced concrete. 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
