Understanding Post Tensioned Concrete And Its Benefits
If you are working with contractors to have a commercial or business building constructed, then the very base of the building will need to be formed first with concrete. As you work with your construction crew, you may hear that post tensioned concrete will be used. If you have never heard of this term, then you are not alone. Keep reading to learn what it is and why it may be suitable for commercial construction.
What Is Post Tensioned Concrete?
Post tensioned concrete is a type of steel strengthened concrete that is typically used to form strong and solid load-bearing constructions. The foundations of commercial buildings, bridges, and overpasses may be formed from the material. Post tensioning is a prestressing process that uses steel cables to reinforce concrete structures. The process is different from the use of steel rods, because rods are simply set in the concrete.
The cables are secured in forms before the concrete is poured over the top of it. The concrete is allowed to cure and then the cables are tightened. The ends of the cables are pulled and then secured to the outside of the foundation or other structure. The tightening of the cables creates tension across the steel before larger and heavier loads are placed on top of the concrete. The tension remains and the steel cables remain tight. This keeps the concrete from shifting or moving underneath large amounts of weight.
What Are The Benefits Of The Concrete?
Post tensioned concrete has many benefits, specifically concerning larger structures. The concrete eliminates the need for seams across the concrete and this helps to reduce shrinkage and cracking. If stress cracks do happen to appear across the surface of the concrete, the steel cables keep the concrete firmly in place. This means that strength is retained overall.
In general, the strength of the tensioned posts or cables allows from thinner concrete constructions. This means that bulky and large foundations may not be needed. This can help to simplify the building and planning process so commercial structures can be completed more quickly. Also, the thinner concrete can reduce building problems when the build location is covered with soft soil. The cables keep the concrete strong and secure so it does not sink into the earth.
