Following the concrete has become poured and permitted to set, the anchors are introduced and, because the steel seeks to return to its original duration, it compresses the concrete. Inside the posttensioning method, the metal is operate as a result of ducts formed while in the concrete. If the concrete has hardened, the metal is anchored to the exterior in the member by some sort of gripping device.
