Aggregate Testing Equipment

The apparatus of the aggregate impact value test consists of: A testing machine weighing 45 to 60 kg and having a metal base with a plane lower surface of not less than 30 cm in diameter.  Level and plane concrete floor of minimum 45 cm thickness are used to support it. The base of the machine should also have provisions for fixing its base. A cylindrical steel cup of internal diameter 102 mm, depth 50 mm and minimum thickness 6.3 mm. A metal hammer or tup weighting 13.5 to 14.0 kg the lower end is cylindrical in shape, is 50 mm long, 100.0 mm in diameter, with a 2 mm chamfer at the lower edge and case hardened. The hammer is arranged in such a way that it should slide freely between vertical guides and be concentric with the cup. It is arranged that the  free fall of the hammer should be within 380±5 mm. A cylindrical metal measure having an internal diameter of 75 mm and depth 50 mm for measuring aggregates. One end rounded tamping rod 10 mm in diameter and 230 mm long. A balance of capacity not less than 500 g, and readable and accurate up to 0.1 g.

 any of various tools or devices with a helical shaft or part that are used for boring holes (as in wood, soil, or ice) or moving loose material (such as snow)

The apparatus for the standard aggregate crushing test as per IS: 2386-1963 (Part IV) consist of the following: The test mold-a 15.2 cm diameter open-ended steel cylinder with square base plate; plunger having a piston of diameter 15 cm, a rod could be inserted for lifting or placing the plunger in the cylinder with a provided hole across the stem of the plunger. A straight metal tamping rod of circular cross-section 16mm in diameter and 45 to 60 cm long, rounded at one end. A balance of capacity 5 kg, readable and accurate up to 1 gm. IS sieve of sizes 12.5mm, 10mm, 2.36mm. A compression testing machine capable of applying load up to 40 tonnes at a uniform rate of 4 tonnes per minute. A cylinder measure having an internal diameter of 11.5 cm and height of 18 cm.

Determines bulk density or unit weight of aggregates.
