The Post Tensioning Institute is a non-profit organization that specializes in prestressed concrete design and construction. The institution is recognized worldwide for it's authority on post-tensioning.
TR 43 is the Indian code used for post-tensioning
Post tensioning is the prestressing of a concrete member by tensioning the reinforcing tendons after the concrete has set
Falsework is usually designed to temporarily support the weight of concrete during curing. When post-tensioning of concrete takes place, the falsework may experience additional loads and stresses due to the forces induced by the post-tensioning tendons. It's important to ensure that the falsework can safely support these additional loads to prevent any failure or collapse.
Post Carbon Institute was created in 2003.
Sanjay Gandhi Post Graduate Institute of Medical Sciences was created in 1983.
The jack efficiency of hydraulic jacks used in post-tensioning work typically ranges from 90% to 95%. This efficiency reflects the jacks' ability to convert hydraulic pressure into effective tensile force applied to tendons, minimizing energy losses. Factors influencing jack efficiency include the quality of the hydraulic system, maintenance, and the design of the jack itself. High efficiency is crucial to ensure accurate tensioning and optimal performance of the prestressed concrete elements.

Yes it is. If a school is a college or university, it is a post secondary institution.
Yes James Lind Institute is accrediated by IOA. I have done my post graduate dimploma in healthcare from them.
Yes, it exists.
PGI means post graduate institute....different cities have this prestigious honoured medical institute with different names.....Same way in lucknow..its actual name is SGPGI.. bt it is popularly known as PGI............. SGPGI= Sanjay Gandhi Post Graduate Institute Here all doctors are at least M.D.
A simple explanation: PRE tensioned- cables are tensioned, and the concrete is cast around it. The tensioning is done BEFORE casting the concrete (PRE = before). POST tensioned- cables are placed inside of ducts or are greased to prevent bonding to the concrete, the concrete is cast around the cables, and then the cables are tensioned after the concrete has reached a desired strength. The tensioning is done AFTER the concrete is cast (POST = after).
