By applying a measured level of stretching power to your steel, the level of compression transmitted into the concrete is usually carefully controlled. Prestressed concrete neutralizes the stretching forces that might rupture everyday concrete by compressing an area to The purpose at which no rigidity is experienced till the strength of your compressed section is prevail over. Since it achieves toughness without having utilizing significant steel reinforcements, it has been accustomed to good impact to make lighter, shallower, and a lot more elegant structures for example bridges and extensive roofs.
