Ascertaining Quality Post Tension Cables

By Anthony Harris


Construction methods are constantly upgraded to ensure that longevity and strength of buildings. Solutions for concrete installations are often made to further strengthen slabs and other structures. This is also to provide them with more stress bearing potential.

Items that require quality for use in homes, office buildings, roads and bridges, power plants and factories, or civil and defense installations often need tensioning and prestressing concrete processes. Post tension cables are the most reliable materials that can help create maximum potential for stress bearing in all these, and also serve to make structures more long lasting. These cables need professionals to handle them to make sure that quality is added for post construction solutions, too.

These things need to be done right. The spaces are measured precisely and built according to plans and specifications. But for strengthening purposes engineers and workers have good margins to where they can safely work. This is to ascertain the process of post tensioning and prestressing cement.

Some unique uses for design and engineering considerations are for cables to be put in before liquid concrete is laid for tall buildings, foundations and residential paving, dams and bridge. They are highly applicable on other facilities like defense and nuclear containment structures, tanks, silos and paving for industrial works. These cables are made of highly tensile steel that have strength and are therefore utilized for concrete reinforcement in several methods.

Post tensioning is used mainly for making thinner but stronger slabs and longer span ranges between standing support units. It is also good for overall improvement in performance as well as time and materials savings. The process is like prestressing, although the application is in both preparation and after the concrete is poured when the entire phase is in its hardening and strengthening application which ideally makes everything cohesive and tighter.

The steel tendons are sheathed inside plastic ducts. After which they are put on a pattern inside a framework that holds the sheaths. Tensioning or stressing is then done. When the poured concrete has hardened, the tendons are then stressed and pulled, after which they are anchored to neighboring units which makes the entire unit a tighter and more integrative complex.

The laying down of tensioned cable systems should be well planned. This is to ensure that repair work or remodeling can be done later, when other elements are added to a structure. It is also done to lessen the danger involved when digging up cables for work below ground levels which is usually a problem for companies that work with laying the groundwork or using underground systems.

Because of this, the strength and integrity of installations are ensured. Many new technologies are now in use and has improved the work. For the wires, it means better techniques in steel manufacture and often using high tech GPR or ground penetrating radar for inspecting systems after construction.

If and when newer methods are introduced in the industry, there are always items for improved stressing and cable use. These are now the most relied upon ways to take any work above projected standards. The field is being upgraded all the time by adding on new knowledge from after every project is completed.
