What is Prestressed Concrete? Concrete can withstand a great amount of compressive stress but it has a very low tensile strength. Because of low tensile strength, concrete gets cracks when subjected to maximum load. Why prestressed concrete is used? When water comes in contact with these cracks the steel gets corroded.
