Our Products
We offer a complete product range of Aggregate Impact Value Testing, Tile Abrasion Tester, Merlin Roughness Tester, Point Load Index Tester and Standard Penetration Tester
The aggregate impact value of coarse aggregate provides a relative measure of the resistance of an aggregate to sudden shock or impact. The oven dried and accurately weighed aggregates are subjected to a total of 15 blows of specified weight and fall and percentage of fines formed in terms of the total weight of the sample is expressed as the aggregate impact value.
Consists of base weighing between 20-30 kg with a lower surface of not less than 30cm and support columns to form a rigid frame work 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+5.0mm. The hammer is provided with a locking arrangement. A metal tup (hammer) weighing 13.5 to 14.0 kg, the lower end of in cylindrical shape, 100mm in diameter and 5cm long with a 2mm chamfer at the lower edge and case hardened. Complete with a cylindrical cup, 102mm dia x 50mm depth, one measure 75mm dia x 50mm deep and a tamping rod of circular cross section 10mm in diameter and 230mm long, rounded at one end.
The following accessories are not part of the standard supply and are supplied at an extra cost.
Test Sieve 10mm, 12.5mm and 2.36mm opening.
Laboratory Oven.
Automatic Blow Counter.
Electronic Balance 500gm x 100 mg / Two Pan Balance.
The tile sample is pressed under a specified load against a grinding path strewn evenly with an abrasive powder revolving at the rate of 30 + 1 r.p.m. At the end of 100 revolutions of the disc the second parallel side of the tile is subjected to wear for an equal number of revolutions of the disc. The wear of tile is measured using a thickness gauge. The Abrasion testing machine consists of a replaceable grinding path fitting on to a disc rotating its vertical axis. The rotating disc and grinding path are enclosed by a circular tray. A bracket holds the specimen. The loading is by a counter balanced lever. A funnel is provided to facilitate charging the grinding path with abrasive powder. Supplied complete with automatic preset revolution counter and one 7.5 kg weight but without abrasive powder and thickness gauge. Suitable for operation 230 V, single phase, Ac supply.
