REVIEW PAPER ON PRE-STRESSED CONCRETE
Keywords:
Post-tensioning, Sulphur coating, Tendon bars, Anchoring.Abstract
The pre-stressing concrete Used for preparing the section is a bit different from the reinforced cement
concrete (RCC.) in concrete technology. The system used for pre-stressing is defined by two methods that are, pretensioning & post-tensioning methods. The pre-stressing by pre & post tensioning device mechanism, introduced for
Anchoring the system in concrete structure element is used for structures. In modern type of Pre-stressing technique
electricity having low value of voltage and high current is adopted in anchoring for a concrete member & A Coating
of sulphur is applied on the steel bars working, as duct material before the casting of concrete member. When the
electricity is supplied in the structure, the sulphur gets melted due to generation of heat in the steel structure and
allowed them for pre-stressing. No provision is required for any duct. The steel alloy structure having high strength
could be anchored by tightening the nuts at both ends. The Pre-stressing in concrete structure is found more effective
then reinforced cement concrete (RCC) technology. So in this paper we will discuss about advanced technique of post
tensioning by replacing duct with sulphur coating on tendon bars.
