Prestressed concrete is a relatively young product. It started to be widely used only during the last few decades, and is still gaining popularity. The reason of its popularity is its usefulness. The main good qualities of prestressed concrete are its high strength and durability. In prestressed con­crete, concrete is combined with steel. This combination is highly advan­tageous and serves the purpose of producing a compressed stress in the concrete as a building material. For this reason any member of beam is under constant compression and as a result has no cracks. In modern times this type of concrete serves as construction material for beams, for pipes, find columns, storage tanks, water towers and the like.
