Post-tensioning is a method of reinforcing (strengthening) concrete or other materials with high-strength steel strands or bars, typically referred to as tendons. Post-tensioning applications include:- office and apartment buildings, parking structures, slabs-on-ground, bridges, sports stadiums, rock and soil anchors, water-tanks. In many cases, post tensioning allows construction that would otherwise be impossible due to either … Read more
Prestressing is now a must-to-have phenomenon in every mega project whether it includes flyovers or dam or whatever. During the design procedures a very important question that arises in the mind of the engineer is; whether to use jacking at one end only or from both ends. Jacking at one end or both ends The … Read more
Pre-tensioning and Post-tensioning is one of the widely used methods to enhance the load carrying capacity of the concrete structures like bridges, flyovers, dam spillways etc. After completing the pre-stressing the ducts or sheath pipes in post-tensioning is to be grouted with a suitable mixture with 24 hours after post-tensioning. Grouting of Post-tensioning Tendons The … Read more
Post tensioning structures are used in the design of buildings, bridges, and other structures with great tensile strength. There are several different types of materials used to make these structures, including steel cables and bars, high-strength steels, concrete, or fiberglass with or without steel fibers. When the material is put under tension during construction (or … Read more
