Post tension slab materials
WebThe post-tensioning technique involves installing and tensioning tendons in a concrete element, thereby applying compressive stress to the material. This compensates for the tensile stress that the concrete may undergo as a result of external loads and reduces or eliminates deformation and cracking.
