Relative Density Apparatus

HS 14.35

soil testing

Primarily meant for determination of void ratio of cohesion less, free draining soils, in loosest and densest states as per IS:2720 (Part XIV), IS:10837. It consists of :

  • Vibrating table, suitable to work with 440V, 50 Hz. Three phase power supply. Vibration deck of size 750 mm square, vibrating at a frequency of 3600 vibrations / min under a 115 kg load and amplitude variable from 0.05 mm to 0.65 mm.
  • Cylindrical unit weight mould, 3000ml capacity.
  • Guide sleeve with clamps for item (ii) above.
  • Surcharge weight with handle for (ii) above.
  • Surcharge base plate with handle for (iv).
  • Cylindrical unit weight mould, 15000ml capacity.
  • Guide sleeve with clamp for item (vi) above.
  • Surcharge weight with handle for (vi).
  • Surcharge base plate with handle for (viii)
  • Handle for surcharge base plate.
  • Metal calibration bar 75 x 300 x 3 mm.
  • Dial gauge holder.
  • Dial Gauge 0.01 mm x 50 mm one no.

Liquid Limit

The test is performed as per IS:2720 (part V) gives the moisture content at which a soil passes from the plastic to the liquid state.
