Prestressed Concrete in Building: Advantages and …

Prestressed Concrete Prestressed concrete is a method for overcoming concrete''s natural weakness in tension. Prestressing tendons (generally of high tensile steel cable or rods) are used which produces a compressive stress that offsets the tensile stress that the concrete compression meer would otherwise experience due to self–weight and gravity loads.
