Advantages

Precast concrete has several advantages over cast-in-situ concrete:

1. When identical members are cast, it is advantageous for the same formwork to be used.
2. As better quality control can be exercised in the factory or yard site, concrete of superior quality can be produced.
3. Smoother exposed surfaces can be produced, which may not require plastering.
4. Precasting work can be carried out under all weather conditions if adequate protection is provided in the casting yard.
5. Precast units can be made to the required shape without much difficulty.
6. When required, they may be dismantled without any breakage.
7. Curing can be done more effectively and economically.
8. Constructions can be erected mostly under all climatic conditions.
9. Buildings may be constructed at a greater speed.
