Prestressed Concrete- Advantages and Disadvantages
Prestressed concrete is the most durable, reliable and strongest concrete that is widely used for the construction of mega buildings and bridges. It is a type of concrete in which high-strength tendons placed in tension regions of the cross-section are stressed during the construction of the element to act against tensile stresses generated due to applied loads. Prestressed concrete is very beneficial to construct crack-free structural members and tackle shrinkage and temperature effects. As a result, the ingression of detrimental agents is prevented which helps in avoiding reinforcement corrosion. The prestressed concrete allows the construction of longer span beams and girders in addition to increase the ultimate load carrying capacity for the same member cross-section. However, the construction process in prestressed concrete requires extensive monitoring and complicated devices and equipment at all stages. Advantages of Prestressed Concrete 1.
