The triaxial cell is very useful for testing soil specimen of dia 38 mm x 76 mm. This can also be used for rock testing purposes. The equipment consists of the following :

• Perspex chambers with anvil and loading plunger for 38 mm dia specimens.
• Pair of plain discs made of Perspex for 38mm dia specimens.
• Pair of porous stone 38mm dia x 6mm thick.
• Split sand former for 38mm dia specimen.
• Sheath stretcher for 38mm dia specimen.
• One dozen rubber sheaths for 38mm dia samples.
• For synthetic rubber 'O' rings for 38mm dia specimen.
• One plastic drainage tube.

Features of Triaxial Cell

The important features associated with triaxial cells are :

• The cell can be opened easily.
• It is leak proof upto 10 kg/sq cm of fluid pressure.
• An oil plug is provided for introducing a thin layer of oil over water. This plug can be also used as an air vent.
• The cell is pivoted with four sleeve packed valves at the base.
• The loading plunger of the triaxial cell has a dial gauge rest.

Application

There are various fields where triaxial cell can be used. Some of the areas where it finds application are :

• Agriculture
• Geophysical/Seismology
• Pavement Material Testing
• Construction
• Rock Testing
• Irrigation
