LIQUID LIMIT APPARATUS (CASAGRANDE)
Liquid Limit is that water content at which a part of soil cut by a groove of standard dimension will flow together for a distance of 1.25 cm. under air impact of 25 blows in a standard liquid limit apparatus. Consists of a brass cup held on adjustable brackets. Supplied with grooving tools along with a 10 mm. gauging block to adjust the height of blow. Fitted with a counter to register the number of blows.

(ii) Hand Operated & Motorized
Category: Material Testing
CONCRETE FLOW TABLE
Recommended for concrete where nominal size of coarse aggregates does not exceed 38 mm. Comprises of machined mild steel table top of 762 mm. diameter, and fitted on a heavy duty Cast Iron frame. A cam action provides a free fall of 12.5 mm. to the table. Equipped with a conical mould of 120 mm. height with base diameter of 250 mm. and top diameter of 170 mm. is also provided along with tamping rod size 16 mm. diameter x 600 mm. long.
AGGREGATE CRUSHING VALUE APPARATUS
Aggregate Crushing Value Apparatus offers a related measure of the resistance of an average to crushing under a compressive load that is gradually applied.
• 150 mm. diameter steel cylinder
• 148 mm. diameter plunger and base plate
The above mentioned cylinder, plunger and base plate are apt for 3/8” to 3/4” size aggregate.
Other size available are 75 mm. & 300 mm.
COMPRESSIVE STRENGTH TESTER
Compression testing Machines are the finest of their types available. Their rugged construction and extreme simplicity makes it possible to operate them with ease and complete dependability.
Compression Testing Machines calibrated with an accuracy of ± 1% as per the requirement of 1828(Grade A) These machines are available in 50 kN, 100 kN, 500 kN, 1000 kN, 2000 kN, 3000 kN, & 5000 kN Capacities.
Compression Testing Machines Classification :
• Analogue models.
• Digital models.
Features of Compression Testing Machines are :
• Highly stable.
• Self-aligning platen assembly.
• Load Gauges are calibrated in Kn against certified Proving Rings, traceable to MSME / NCCBM.
• Suitable for testing cubes and cylinders of various sizes, Cubes from 50 mm.³ to 300 mm.³ Cylinders from 100 mm. to 300 mm.
• Logged data printing facility through a parallel port Interface available in digital base models.
Pace rate (display only ) available in Digital models.
2000 KN compression testing machine consists of a steel base and cross head welded along side with heavy-duty plates. The hydraulic
loading jack is fixed on the base and lower platen rests entrally on the jack. The upper platen is attached to the head plate. The upper platen has got a spherical seating for a self-aligning action. For adjusting the vertical day light spacers are used as per the specimen height requirement. Micro safety switch has been incorporated within digital display unit assembly, which will switch off the motor when load is between 1800-1850 kn to avoid overloading of the loading frame.

AUTOMATIC COMPACTION HAMMER & ASSEMBLY FOR BITUMEN SAMPLE
The automatic compactor eliminates the tidious process of manual compaction and an even degree of compaction is achieved. The drive mechanism lifts the weight of 4.5 kg. and drops it through a correct height of 457 mm. The rammer foot is removable, which facilitates preheating. A compaction pedestal with specimen holder is fixed to the base. An automatic blow counter enables the number of blows to be preset before each test and automatically stops the machine on completion. Suitable for 220-240 volts, 50 Hz, single phase.
