Aggregate Testing Equipment

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

Specification :
Air Entrainment Meter of a small amount of air in the cement concrete has been found to improve considerably the durability of concrete. Further, when the use of admixtures is made to increase the 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. Each apparatus is supplied complete with a calibrating cylinder, pressure gauge, funnel, measuring jug, straight edge and a hand pump.

Specification :

• Capacity: 0.005 m3 (5 Litres)
• Suitable for aggregate size upto 38 mm
• Dimension: 370X370X550 mm

Cat No : AT-199

The machine consists of a hollow cylinder, mounted on a sturdy frame on ball bearings. The drum is rotated 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.

Specification :

• Speed: 30-33 rpm
• Power: 415 V, 3 Phase, 50 Hz, AC supply
• Outside Dimension: 1100x780x1000 mm

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.
