CONSOLIDATION APPARATUS (SINGLE GANG):

AS PER IS: 2720 (Part-XV), BS 1377. ASDTM D-2435

Introduction: 

• Consolidation test is Uni-dimensional test considered extremely important in soil mechanics.
• Sample taken from adjacent areas of a single site show different settlement even when tested using same techniques.
• Soil of similar strength may show varying consolidation.
• Samples are very carefully prepared and vertical settlement of the specimen in saturated or drained conditions carefully recorded when known load is applied.

General Description and Specifications:  The standard outfit comprises of the following items.

• Loading unit: maximum capacity 20 kg/cm sq. having a loading yoke connected to a lever arm with a counter balancing adjustment and having a lever ratio of 1:1, the whole assembly being mounted on a sturdy steel frame stand. The loading unit is so designed that it can be used for consolidation cells of different diameters as well as different diameter floating ring type consolidation cells.

• Fixed ring type consolidometer (Odometer) cell assembly for testing 60mm dia x 20 mm thick specimen comprising:
  • Fixed ring for specimens 60 mm dia x 20 mm thick with guide ring.
  • Top and Bottom Porous stones for 60 mm dia specimen.
  • Perforated Pressure pad, Channeled base with water inlet and Gasket.
  • Flanged Water Jacket, water reservoir with plastic tube and pinch cock.
  • Set of weights to give a pressure of 10 kg/cm. sq. on 60 mm dia specimen, comprising:
    • 7 Nos. 0.05 kg/sq.cm.,
    • 5 Nos. 0.1 kg/sq.cm.,
    • 6 Nos. 0.2 kg/sq.cm.,
    • 6 Nos. 0.5 kg/sq.cm., 
    • 5 Nos. 1.0 kg/sq.cm.
• Supplied complete as above but without dial gauge.

Standard Accessories:

• Dial Gauge 0.002 mm x 10 mm.
• Extension piece, 40 mm long.
• Test forms pad of 50 for one Dimensional Consolidation.

Optional Extras:

• Varying head stand pipe, 50 cms long with mm scale.

• Fixed ring type of consolidometer (Odometer) cell assembly for 50 mm. dia x 20 mm thick specimens complete with fixed ring guide ring, pair or porous stones, perforated pressure pad, channeled base, gasket and flanged water jacket. Set of weights to give a pressure of 10 kg/sq. cm, on 50 cm. dia specimen.

• Fixed ring type of consolidometer (Odometer) cell assembly for 70 mm dia x 20 mm thick specimens, complete with accessories as above. Set of weights to give a pressure of 10 kg/sq.cm. on 70 mm. dia specimen.

• Fixed ring type of consolidometer (Odometer) cell assembly for 100 mm dia x 25 mm thick specimens complete with accessories as above. Set of weights to give a pressure of 10 kg/sq.cm. on 100 mm dia specimens.

Note: Electronic Consolidation Apparatus can also be supplied. In place of a dial gauge, a very sensitive LVDT transducer with a digital displacement meter is provided. Suitable for operation on 230 volt A.C.
