Soil & Geotechnical Testing Equipment

The apparatus comprises of the following - Loading Unit :

Supplied with loading yoke with direct and lever for applying load. Normal stress capacity 8Kg/Sq.cm. Load is applied either directly or through a counter balanced detachable lever. Provision is made for the load to be applied either through a steel ball recessed in the loading pad or direct through a boss on the pre calibrated loading. yoke. The loading unit is provided with V strips and roller strips for frictionless movement of shear box housing.

Consists of loading unit, shear box assembly for 60 mm x 60 mm x 25 mm complete with two halves of loading pad, one base plate. All made of gunmetal with two porous stones. Share box housing of gunmetal, specimen Cutter of steel with set of weight to give normal stress of 3 kg/cm2. through lever as follows.

Unit is electrically operated to give the following 12 rates of strains from 1.25, to 0.0002mm/min. The apparatus is suitable for operation on 230 volts single phase A.C. supply. With dial gauge and proving ring.

Fabric is clamped to give an inner diameter of 15 cm and a 50 mm CBR plunger is pushed centrally through a fabric at a specified rate. The load at failure is the push through load and when divided by the cross-sectional area of the plunger, gives CBR push through resistance.

Meets: - ASTM D- 6241, BS-6906 part 4, ISO-12236:2006

The liquid limit, defined as the moisture content at which the soil passes from the plastic state to the liquid state, is very helpful in the classification of the potential properties of the soil material. The liquid limit gives a measure of the shearing resistance which a soil has when mixed with water. Casagrande’s Method or Cone Penetrometer Method can determine the liquid limit of soil.

Durability test is having arrangement to rotate the handle with AC motor having gear box. The pre set type indicator is provide to check the total count. The arrangement is also provided to apply the load on the lever for testing.

Axial Strength test has been provided with the Digital force gauge (HTC make) having capacity of 100 Kg it is having the arrangement that force can be set by rotating wheel and one dial gauge also provided to check the deflection of the lever. The arrangement is also provided to apply the load on the lever while testing
