Yet another innovation in masonry construction is using prestressed concrete. It really is attained by either pretensioning or posttensioning processes. In pretensioning, lengths of steel wire, cables, or ropes are laid while in the vacant mildew and afterwards stretched and anchored. Once the concrete continues to be poured and allowed to established, the anchors are released and, given that the steel seeks to return บริษัทเอสเอชซี สหะชัยคอนกรีต จำกัด to its first duration, it compresses the concrete. While in the posttensioning method, the steel is run by means of ducts formed inside the concrete. If the concrete has hardened, the steel is anchored to the exterior from the member by some type of gripping machine.
