The pre-stressing concrete technology is quite different from Rcc. Concrete Technology. The pre- stressing system devices are of two types, pre- tensioning & post-tensioning . By using prestressing for pre &post tensioning device mechanism development of Anchoring system in concrete structural element. In modern type of Pre stressing electricity with Low voltage and high current is used in anchoring device for a concrete member & sulpher Coating as a duct material before the casting of concrete member. While supplying electricity in the structure sulpher get melted up because heat generated in the structure. The structure could be anchored by nutting at both the ends.
