Once the concrete has become poured and permitted to established, the anchors are unveiled and, given that the stamped concrete metal seeks to return to its authentic duration, it compresses the concrete. In the posttensioning system, the steel is operate by means of ducts fashioned inside the concrete. In the event the concrete has hardened, the metal is anchored to the outside on the member by some type of gripping device.
