Our array of cutting -edge and sophisticated aggregate testing instruments are dependable and assure highest level of accuracy in testing.

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 Liters), suitable for aggregate size up to 38mm. Each apparatus is supplied complete with a calibrating cylinder, pressure gauge, funnel, measuring jug, straight edge and a hand pump.

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.

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.

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.

Flakiness & Elongation Index Test Gauges

Quality Standard: As Per IS 2386 (P-I)

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.


Quality Standard: As Per IS 2386 (P-III)
Specification: Specific Gravity is the ratio of the weight in air of a given volume of a material at a standard temperature to the weight in air of an equal volume of distilled water at the same stated temperature. The Pycnometer Bottle can be used to test a wide range of materials from clay to sand and gravel smaller than 10mm. It consists of 1kg Glass Jar with Brass Cone, Locking Ring and Rubber Seal.

Buoyancy Balance (Determination of Specific Gravity)

Specification: The density of hardened concrete specimens such as cubes and cylinders can be quickly and accurately determined using a Specific Gravity / Buoyancy Balance. The apparatus consists of a rigid support frame, incorporating a water tank mounted on a platform. A mechanical lifting device is used to raise the water tank through the frame height immersing the specimen suspended below the balance. Any type of Electronic Balance fitted with an under bench weighing facility can be fitted. The balance supplied can also be used as a standard weighing device, thus providing a versatile and comprehensive weighing system in the laboratory.

Sieve Shaker

Specification: The Sieve Shaker is used to make the process of sieving easier and quicker. The shaker effects a more elaborate and standardized sieving action to produce accurate results and eliminate personal errors involved in manual sieving. The shaker can carry upto 8 sieves. The shaker produces the gyratory as well as the tapping motion.

Riffle Sample Divider

Specification: For the rapid collection of true representative samples from aggregates, sand and fillers, sample divider is required. Riffle Sample Divider consists of a metal box fitted with a series of chutes of equal width which discharge the material alternatively in opposite directions into separate pans. The chutes of the riffle are steep enough to allow rapid flow of the material. The apparatus is supplied with two containers and a sampling scoop.
