Pre Stressing Concrete

Prestressed concrete is a structural material that allows for predetermined, engineering stresses to be placed in members to counteract the stresses that occur when they are subject to loading. It combines the high strength compressive properties of concrete with the high tensile strength of Prestressed concrete is a form of concrete used in construction. It is substantially “prestressed“ ... While pre-tensioned concrete uses tendons directly bonded to the concrete, post-tensioned ... Following concreting and tensioning, the ducts are pressure-grouted and the tendon stressing-ends sealed against corrosion. :2
