SPECIFICATION

  • Permeability testing apparatus
  • Casagrande method in mechanical form is known as liquid limit method and has been in use for soil mechanics for a number of decades. 
  • For determination purpose liquid limit is that water content at which a part of soil, cut by a groove of standard dimensions, will flow together for a distance of 1.25cm under an impact of 25 blows in a standard liquid limit apparatus.
  • The soil at the water content has some strength which is about 0.17N/cm. sq. (17gms/sq.cm.).
  • At this water content soil just passes from liquid state to plastic state. It consists on a brass cup held on an adjustable bracket.
  • The cup can be adjusted for a fall of 1 cm and can be raised an dropped on a rubber base of standard hardness by cam action.
  • Complete with one Casagrande grooving tool, one ASTM grooving tool and a height gauge block.
