What is difference between pre tension and post tension precast girders of bridge?
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). ...

Pre stressed concrete compared to Post tensioned concrete?
Prestressed concete made using high tensile wires which is stressed (as per the design load) before concreting, and post tensioned concrete made of Strands covered with duct, in this, wires/strnads are stressed after concreting then the ducts are grouted using cement slurry.. ...
What is the definition of pre tensioned concrete?
Prestressed or pretension concrete uses wires and reinforcement to strengthen concrete's inherent weakness. It prevents cracking and buckling and adds years of useful life to the building structure. ...

What is the method of increasing the strength of a beam or rod by applying tension called?
Pre tensioned concrete best illustrates this concept. Tension in the rods becomes compression in the concrete once the cables are cut at the ends of the beam. ...
