ASTM D3080; BS 1377:7; AASHTO T236, CENISO/ TS 17892-10 The test covers the determination of consolidated drained shear strength of a soil material in direct shear. This Automatic Direct / Residual Shear Test Machine is motorized and floor mounted. Supplied with carriage assembly load hanger and integral 9:1, 10:1 and 11:1 lever loading device as standard. The beam loading device which is used to amplify the vertical load on the shear box assembly can receive up to 50 kg of weight. The total load on the specimen can reach up to 5 kN (5000 N). The machine accepts 60 mm square, 100 mm square, 60 mm dia. round, 100 mm dia. round and 2.5 inc. dia. round shear box assemblies. All shear box assemblies are designed to contain water that surrounds the specimen. The Assemblies consist of a shear box with a rigid wall square or round hole complete with a vertical loading pad grooved back face, a grooved retaining plate, 2 pcs.porous plates, 2 pcs. plane grids and 2 pcs. perforated grids. The shear machine is driven by high resolution servomotor and gear box assembly. Speed range is fully stepless variable over the range 0.00001 to 9.99999 mm/min for both direction( forward and reverse). After test the reverse speed is 10 mm/min.). 5 kN load cell is used for load measurement. 10 x 0.001 mm and 25 x 0.001 mm sensitivity linear potentiometric transducers are used for vertical and horizontal displacement measurements respectively. Displacement limits are controlled by limit switch. Shear Box Assembly, Slotted Weight Set and other optional accessories including specimens cutter and extrusion dolly should be ordered separately The Automatic Direct Residual Shear Test Machine is supplied complete with ! Load Cell 5 kN ! Linear Potentiometric Displacement Transducer (10x0.001 mm) ! Software

IS 2720 (PART XIII) The apparatus comprises of the following. Loading Unit: Supplied with load yoke with direct and lever system for applying load. Normal stress capacity 8 kg/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. Shear Box Assembly: Comprising direct shear box in two halves for a square specimen size 60 x 60 x 25mm one pair of plain gripper plates, One pair of perforated gripper plates, one pair of porous stones, one top of loading pad. Shear Box Housing: Accommodates the direct shear box assembly. Complete with two ball roller strips. Specimen cutter: for cutting 60 x 60 x 25 mm. Specimen form larger samples. Set of weights to give a normal stress of 3kg/sa.cm. Through larger as following : To give kg/cm. sq. Qty. 0.05 4 nos. 0.1 1 no. 0.2 1 no. 0.5 3 nos. 1.0 1 no. Essential Accessories: High sensitivity compression proving ring. Cap 200kg. One consolidation dial gauge 0.01mm x 25mm and one strain dial gauge 0.01mm x 25mm

This apparatus is used for measuring pore water pressure and pore air pressure in soils. This is as per the principals outlined in the book “ measurement of soil properties in triaxial tests” by A.W. BISHOP and D.J. HENKEL. This is used as an accessories for triaxial test apparatus. Specification: The apparatus consists of a panel for wall mounting on which are fitted 1.0 to 10kg/cm sq x 0.1kg cm. sq. a pressure gauge, bourdon tube type 15 cm dia. Manometer: Glass u-tube manometer for measuring low positive pore pressures negative pore measures and checking zero error of pressure gauge. It is provided with a mercury trap (mercury supplied at extra cost.) Null indicator made out of clear transparent Perspex with mercury trap and cursor to indicate the mercury level. Burette: 50ml burette for measuring the volume change in the soil specimen. Pressure pump fitted with four sleeve packed valves, operated by means of a hand wheel on the end of the piston rod which is threaded through the pump cap and gives a smooth, fine adjustment of pressure. Copper coil and water reservoir is fitted on board with complete stand assembly. The unit is tested against leaks up to 10kg/cm sq.

Same as ZI 3058, but fitted with pressure gauge 0-20kg/cm2 x 0.2kg/cm sq. Spares: Polythene tube 3mm bore x 5 mm. O.D.

It is designed for application of cell pressure upto 10kg/cm2 on a triaxial specimen in the triaxial cell. The unit is mostly used in routine tests which last for about 10 to 15 minutes wherein the variations of cell pressure can be tolerated. Specification: The apparatus consists of a pressure chamber which has a flanged top cap fitted with a 10 kg/cm2. Pressure gauge and a valve for pumping in air. Water inlet and drain cock are fitted to the chamber. The foot pump supplied easily develops a pressure of 10 kg/cm2 Complete with connecting pressure hose. Note: Also available 20Kg/cm2

Features: ! Two pillar type ! Detachable Frame ! Enclosed motor and gear system ! Jewel lamps indicating direction of motion ! Operational ease ! Useful for Triaxial and CBR Tests The Load Frame consists of a cabinet which houses the gear system and motor with sturdy angle iron frame. the loading is done through the bottom loading platen, which is carried on a lead screw, which advances upwards. the top load bracket, which slides over two upright pillars, can be positioned at any desired height and locked. It carries a screw adapter for standard Proving rings and Load Cells. The loading part of the unit is detachable from the main unit for ease of transport and to avoid damage to the tension rods. Rates of Strain: 30 fixed speeds between 0.00048 mm/min and 6.00 mm/min. Suitable for operation on 220 V, 50 Hz, single phase, AC supply.
