Aggregate Testing Equipment

Cat No : AT-152-1
NAME : Air Entrainment Meter
Quality Standard : As Per IS 1199

Specification :
Entrainment of a small amount of air in the cement concrete has been found to improve considerably the durability of concrete. Further, when use of admixtures is made to increase workability of concrete, a check of the air content is required to ensure that the percentage of air remains between 1 to 2% to get the optimum performance of the concrete structure. Air Entrainment Meter is having a capacity of 0.005 m3 (5 Litres), suitable for aggregate size upto 38mm. Each apparatus is supplied complete with a calibrating cylinder, pressure gauge, funnel, measuring jug, straight edge and a hand pump.

Cat No : AT-199
NAME : Aggregate Impact Value Test Apparatus
Quality Standard : As Per IS 2386 (P-IV)

Specification :
Aggregate Impact Value The machine is used for determining the aggregate impact value. The Sturdy Construction consists of a base and support columns to form a rigid framework around the quick release trigger mechanism to ensure an effective free fall of the hammer during test. The free fall can be adjusted through 380±5mm. The hammer is provided with a locking arrangement. Aggregate impact value test apparatus is supplied complete with a cylindrical measure of 75mm dia x 50mm depth, an automatic blow counter and a tamping rod.

Cat No : AT-200
NAME : Aggregate Crushing Value Test Apparatus
Quality Standard : As Per IS 2386 (P-IV)

Specification :
The selection of proper aggregate for a given application is essential to attain the desired quality. Various characteristics are required to be determined for the selection of appropriate aggregate from the wide range available. Crushing Value Apparatus is used for measuring resistance of an aggregate to crushing. Made of Mild Steel comprising of:

• Cylindrical Cell, 150mm internal dia x 130 to 140mm height.
• Plunger, 148mm dia x 100 to 115mm height.
• Base Plate, 200 to 230mm square x 6mm thickness.
• Tamping Rod, 16mm dia x 450 to 600mm length.
• Metal Measure, 110mm internal dia x 180mm height.

Cat No : AT-203
NAME : Los Angeles Abrasion Testing Machine
Quality Standard : As Per IS 2386 (P-IV)

Specification :
Los Angeles Abrasion Testing Machine is used for determining the resistance to wear of small size coarse aggregates and crushed rock. The machine consists of a Closed hollow cylindrical steel drum rotating around its horizontal axis on ball bearing units mounted on a sturdy base framework at a speed of between 30-33 rpm. Supplied complete with subtracting revolution counter to preset the number of revolutions, a sample collection tray for removal of the sample on completion of testing and set of 12 abrasive charges.

The Machine is fitted with 1 HP Motor. Suitable for Operation on 440V, Three Phase, 50Hz, AC Supply.

Cat No : AT-215 & AT-216
NAME : Flakiness & Elongation Index Test Gauges
Quality Standard : As Per IS 2386 (P-I)

Specification :
Aggregates which are flaky and/or elongated will often lower the workability of a concrete mix and may also affect long term durability. In bituminous mixtures, flaky aggregates make for a harsh mix and may also crack and break up during compacting by rolling. The flakiness of aggregate is determined by measuring the thickness of individual particles. Hence we offer thickness gauge and length gauge to check flakiness and elongation index of the aggregate respectively.
