CB Sowmya
For In-Situ piles, we don't generally use vibrators because Vibration in such depths may alter the soil structure and may even cause collapse. Therefore the type of concrete used is self-compacting concrete. This concrete does not need external vibrations to compact.

The SSSI are sites that are preserved due to its rich flora, fauna, geology and geomorphology. These areas have developed their rich heritage through centuries. Hence they are taken utmost care of. The rules of construction are quite stringent here.
- Before the construction process, necessary surveys must be taken to prove that the SSSI wont be affected by the construction process or after it.
- Proper planning and approval is needed.
- Permission from the statutory authority is needed.

Mac Arthur pile is a cast In-Situ pile of uniform diameter.
- A shell casing is driven into the ground with the help of a driving core.
- After the desired depth is reached, the core is removed.
- Now a corrugates steel shell is inserted again into the casing.
- The concrete is poured into the corrugated steel shell and simultaneously the outer casing is removed.
- If the outer casing is left inside, the structure would be even more safe but it is not economical.

Stucco is used like any other plaster to cover the bricks or concrete surfaces and give an appealing and finished look.
It is made up of OPC, fine aggregate and water. It is very common in India and goes by the name “Plaster“. The advantages of Stucco is that it is very durable and can be further strengthened by adding fibers into it.
However in other countries, “Plaster” is made up of Gypsum or Lime instead of OPC. When cement is used as a binder it is called as “Stucco”.
