Once the concrete has long been poured and allowed to set, the anchors are launched and, as being the metal seeks to return to its initial size, it compresses the concrete. From the posttensioning course of action, the metal is operate by ducts fashioned from the concrete. Once the concrete has hardened, the metal is anchored to the outside of the member by แผ่นพื้นสำเร็จรูป some type of gripping system.
