The cell is useful for testing 38mm dia x 76mm high soil specimen. Transparent Perspex chamber with anvil and loading plunger, the cell is easily opened by releasing four nuts of

the tie rods. It is leak proof up to 10kg/cm.sq. Fluid pressure. An oil plug which can also be used as an air vent is provided for introducing a thin layer of oil over water. This provides

effective sealing at the plunger for long duration tests. The cell is fitted with four sleeve packed valves of no volume change type on the base. These valves are used for cell pressure, pore water pressure, drainage or back pressure. The loading plunger of the cell has dial

gauge rest.

As Per IS 2720 (Part XBII)- 1966 BS 1377; EN DD ENV 1997-2; ASTM D2434;AASHTO T215 Clays and silts are tested using the technique. Flow of water through the specimen is

observed by monitoring the rate of fall of water in the tube. It is essential that soils of very

low permeability are sealed inside the cylinder to prevent seepage along the sides of the specimen. Before testing, the specimen must be completely saturated with water as the presence of air will restrict the flow of water. Three glass stand pipes a stand with nine glass tubes of 6mm, 10mm, 20mm, 25mm, 40mm, 50mm, 60mm, 70mm, 75mm, bore tube is provided with over flow arrangement for constant head tests. The remaining tubes are used for falling head test.

As Per IS 2720 (PART X) ASTM T 208 This is similar to above with the added advantage of a motorized drive permitting constant rates of stain. Specification : Comprises a screw

operated load frame, cap.5000kg with a gear box and motor drive giving 1.25 mm/min. Rates of strain, a pair of cone seating, adaptor for proving ring, and stain dial gauge bracket. Supplied with one pair of male/female coning tools for 38mm dia. samples but without ring

and dial gauge. Suitable for operation on 230 V, Single Phase A.C. Supply. Accessories : Coning tools in pairs (Male & Female) for samples having diameter 38mm, 50mm, 75mm

& 100mm.

Suitable to cut/drill cores of concrete, rocks, stones, tiles or the similar materials. The machine is suitable for core samples of size upto 150 mm diameter with the help of thin
walled diamond bits which are at extra cost. The machine has sturdy base with pillar support in which rack and pinion is provided for adjustment in height and penetration assembly. The
leveling screws are provided at the base. For gripping the sample in position suitable grips are provided. A suitable diesel engine is fitted in the machine with cooling arrangement with water. The base frame is also fitted with wheels for ease of transportation.

Dimension approx, are as under: Height : 1300 mm, Base : 600 x 1200 mm, Head travel on rack : 350mm, Drill speeds : 900 R.P.M. for soft samples and 350 R.P.M. for hard Samples,

This is for the determination of the sub sieve particle distribution in a soil sample by mechanical analysis. An analysis of this kind expresses quantity the proportions by weight

of the various sizes of particles present in the soil. It is recommended as a standard procedure

to use dispersion agent to avoid flocculation. The apparatus consists of a sliding panel which moves up and down by means of a screw allowing Anderson pipette fixed to it to be raised

or lowered vertically. A sedimentation tube is held by a laboratory clamp provided on the

stand below the pipette. The depth of immersion is measured by a scale graduated in mm at the side of the sliding panel. Supplied complete with Anderson pipette 10ml. At the side capacity made from glass, and a sedimentation tube also of glass of 500ml capacity and

50nos. Test form pads. ACCESSORIES & SPARES : i) Sedimentation Pipette (Anderson pipette) 25ml, ii) Sedimentation tube 100ml, iii) Sedimentation pipette 10ml, iv)

As Per IS 2720 (Part XBII)- 1966 BS 1377; EN DD ENV 1997-2; ASTM D2434;AASHTO T215 This equipment is used for testing the permeability of granular soils (sands and

gravels).The specimen is formed in a permeability cell and water is passed through it from

a constant level tank Take-off points located along the sides of the permeability cell are connected to three manometer tubes mounted on a panel complete with a meter scale. Water passing through the specimen is collected and measured, either for a specific quantity or over a period of time. The reduction of head is noted from the variation of water level in the manometer tubes. Comprising three glass tubes of constant bore, meter scale and connecting tubing for cell pressure take-off points, all mounted on a free-standing panel. Manufactured from transparent plastic with attachment for wall mounting. The inlet, outlet and overflow pipes are fitted to the base of the tank and can be adjusted for height within the tank. Supplied complete with connecting tubing.

Clays and silts are tested using the ‘falling head’ technique. Flow of water through the specimen is observed by monitoring the rate of fall of water in the tube. It is essential that soils of very low permeability are sealed inside the cylinder to prevent seepage along the sides of the specimen. Before testing, the specimen must be completely saturated with water as the presence of air will restrict the flow of water Specification : The equipment comprises one each : - Gun metal mould - 100mm I.D. x 127.3mm high x 1000ml Volume. - Gun metal mould extension collar - 100mm dia x 60mm high for the above mould. - Gun metal drainage base plate with a recess for a porous stone, GI Tank

It is a motor driven mechanical compactor useful for soil compaction into 100mm to 102 mm & 150mm to 152.4 mm diameter moulds. Two sets of Rammers are provided, one of

2.5 kg and arranged for 300 mm & 305 mm drop and other 4.5 kg and arranged for 450 mm

& 457 mm drop. The rammer assembly is provided with a ratchet and pawl arrangement to lift it from the top of the soil layer. When the rammer reaches the required height the pawl

release the rammer which falls freely on soil surface. The release mechanism is operated by

an arm moving up and down which is connected to a reduction gear coupled to the motor through another arm. An automatic blow counter fitted to the compactor is used to set the

number of blows. The base plate of the specimen mould is to be fitted to the rotating base
