Prestressed concrete - SlideShare

PRESTRESSED CONCRETE Prestressed concrete, invented by Eugene Frevssinet in 1928 is a method for overcoming concrete’’s natural weakness in tension . It can be used to produce beams , floors or bridges with a longer span than is practical with ordinary reinforced concrete. It can be accomplished in three ways: pre- tensioned concrete, and bonded or unbonded.
