Shrinkage of concrete and "creep" of concrete and of steel reinforcement are potential sources of prestress loss   and are provided for in the design of prestressed concrete. Shrinkage:The magnitude of shrinkage may be   in the range of  0.02% depending on the environmental conditions and type of concrete.With pre- tensioning, shrinkage starts as soon as the concrete is poured
