The article provides information about prestressed concrete. While the compressive strength is very high, it has a very low tensile strength. Reinforced concrete is a solution for this problem. However, the advantage of prestressed concrete is that it requires only about one-fifth of the steel and a third as much concrete compared to reinforced concrete.
