Aggregate Impact Value


Shivam Instruments India
IS: 2386 (Part 4), IS: 9377-1979
It is for determining the aggregate impact value and has been designed in accordance with IS: 2386 (Part 4), IS: 9377-1979. 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 ± 5 mm. The hammer is provided with a locking arrangement. Following model of Aggregate Impact Value Apparatus is available.

Los Angeles Abrasion Testing Machine
IS: 2386 (Part 4), 10070, ASTM C131, AASHO T96
This machine is for determining the resistance to wear of small size coarse aggregates and crushed rock. The machine consists of a hollow cylinder, mounted on a sturdy frame on ball bearings. A detachable shelf which extends throughout the inside length of the drum catches the abrasive charge and does not allow it to fall on the cover. The drum is rotated at a speed of 30-33 rpm by an electric motor through a heavy-duty reduction gear. Motor is suitable for operation on 220 V, 1 phase, 50 Hz, AC Supply. Supplied complete, with a tray for collection of the material, and abrasive charge

Dorry Abrasion Testing
BS:812
This is for aggregates resistance to abrasion. The apparatus consists of a metal disc which revolves in a horizontal plane on a vertical shaft. A suitable attachment for holding the specimen with is axis vertical and its lower end pressed with a prescribed pressure against the surface of the disc (the distance from the centre of specimen to the centre of shaft being 25 cm) is provided. A convenient funnel for feeding sand continuously upon the rotating disc is also provided. The machine is fitted with a ¼ h.p. electric motor, driven through a reduction gear to give 28-30 revolution of the disc per minute. Suitable for operation from 220/230 volts single phase, A.C. supply
