Shuttering in building construction
We need shuttering to mold the concrete into desired shape. It should have the following properties:
- It should be strong and firm enough to withstand the weight of concrete, bar and those acting on it and the vibrations generated by the vibrator.
- The surface of the firm in contact with concrete should be flat, smooth, waterproof and non-absorbent. Shuttering oil should be used properly on its surface.
The following instructions of IS 456 : 2000 must be observed for the duration of shuttering base / sacking (if the temperature exceeds 15°C):
Note: If the temperature is below 15°C then the above period may be extended.
