As Per IS 2720 (PART-VII) ASTM D 427, BS 1377, AASHTO T 92.

Shrinkage limit is the maximum water content at which a reduction in water content does not cause an appreciable reduction in volume of the Soil Mass. At shrinkage limit, on further

reduction in water, air enters in to the voids of soils and thus keeps the volume constant.

Optional: Motorized Liquid Limit also Available

Casagrande method in mechanical form is known as liquid limit method and has been in use for soil mechanics for a number of decades. The liquid limit data of soils is useful to correlate

mechanical properties of soil, such as compressibility and lower shear strength. Liquid limit

is the water content at which soil passes from zero strength to an infinite strength, hence the true value of liquid limit cannot be determined. 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

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.

It is used in large road construction projects has increased considerably in recent years. This apparatus, mounted on a rolled steel joint cantilevered from the back of the truck or fitted

to the underside of a mobile frame, can be used to determine the bearing capacity of soils quickly and efficiency. This method of testing in-situ, using piston penetration, is useful for

determining the load carrying capacity in the field, when the in -place density and water contents are such that the degree of saturation is 80% or greater. When the material is coarse grained and cohesionless so that it is not affected b changes in the water content and when

the material has been in- place. Similar to above but supplied with bench mounting type

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.

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
