Prestressed concrete is the most robust, effective and solid material used to construct mega-buildings and bridges. It has made significant contributions to the construction, prefabrication, and cement industries.
Advantages of Prestressed Concrete
- Longer span length raises undisturbed parking and floor storage.
- It can create more slabs than conventional thinner slabs, which are essential for high-rise construction as with the same amount of cost.
- As the size of the span is longer, there is a need for fewer joints than conventional RC systems.
- As the joints are the largest locus of failure in a concrete building, maintenance costs are also minimized during the design life due to fewer joints.
- Durability for the long term.
- Great finish of concrete put.
- This needs a smaller number of building materials.
- This avoids strains that are higher than normal systems of RCC and clear from fractures.
Disadvantages of Prestressed Concrete
- This needs cement with high strength and metal wires with high tensile strength.
- The main disadvantage is that the building requires additional special equipment such as jacks, anchorage, etc.
- Under professional management, this needs highly skilled workers. Building costs were slightly higher than the RCC systems.
