After the concrete continues to be poured and allowed to established, the anchors are produced and, as the metal seeks to return to its original duration, it compresses the concrete. Within the posttensioning process, the steel is operate by ducts fashioned during the concrete. In the event the concrete has hardened, the metal is anchored to the exterior with the member by some kind of gripping product.
