Compaction Test





Modern forms of construction such as earthen dams, retaining walls, highways, airports etc., require artificially placed soil. Compaction is placement of the soil in a dense state (a) to decrease future settlements (b) to increase shear strength and (c) to decrease permeability. The purpose of laboratory compaction studies is to evaluate the optimum amount of water for the given soil which will give the maximum density. These tests are conducted either by dynamic or static methods.

Conforms to IS : 10074
It comprises of :
Proctor type compaction mould of 100 mm. diameter x 127.3 mm. high with a 1000 cm capacity made of gun metal, consisting of mould body, base plate and collar. Compaction rammer made from corrosion protected steel is of 2.6 kg. weight, 50 mm. diameter with a 310 mm. controlled drop.


LM173314 / 3315


LM173311 : Mould with base plate and collar made of gun metal.
LM173312 : Rammer 2.6 kg. x 310 mm. drop.

LM173313 : Metal straight edge 300 mm. long for trimming soil in the compaction mould.

LM173314 : Rammer for heavy compaction test 4.89 kg. weight with a 450 mm. controlled drop.  The rammer diameter is 50 mm.

LM173315 : Compaction mould of 150 mm. diameter x
127.3 mm. high with 2250 cm capacity comprising of mould body, base plate  and collar made of gun metal.

LM173316 : Mould, 1000 cm with base plate and collar made of steel.






This machine is designed to compact specimens automatically and uniformily  for  Proctor  and  CBR  tests, eliminating the laborious hand compaction method.  The  rotation  of  the  mould  after  each  stroke ensures complete coverage of the soil surface. The height of the rammer drop can be adjusted from 310 to 450 mm. or vice-versa by a connecting arm.  Two hammers, one of 2.6 kg.x 50 mm.diameter for   light  compaction  and  4.89kg.x75  mm.diameter                                                                                         for  heavy compaction are supplied as a standard component with the unit. A graduated dial incorporating a microswitch, enables   the   number of  blows  to be pre-set before  each  test  and automatically stops the machine on completion.
Wired for 230V., sph. 50 Hz.
