Another innovation in masonry building is using prestressed concrete. It is achieved by either pretensioning or posttensioning procedures. In pretensioning, lengths of steel wire, cables, or ropes are laid while in the empty mold then stretched and anchored. Following the concrete has become poured and permitted to established, the anchors are launched and, since the steel seeks to return to its authentic size, it compresses the concrete. Inside the posttensioning process, the steel is run by means of ducts shaped within the concrete. Once the concrete has hardened, the steel is anchored to the ห้างหุ้นส่วนจำกัดสหคอนกรีตอัดแรง exterior in the member by some type of gripping machine.
