After the concrete has become poured and permitted to established, the anchors are released and, as being the metal seeks to return to its authentic duration, it compresses the concrete. In the posttensioning method, the metal is run by ducts formed from the concrete. When the concrete has hardened, the metal is anchored to the outside in the member by some type of gripping gadget.
