MicroDeval Apparatus. The increasingly popular MicroDeval test measures abrasion resistance and durability of mineral aggregates. An aggregate sample is placed in a sealed stainless steel jar with an abrasive charge of up to 5,000g of diameter stainless steel balls and water, and then rotated at 100rpm for two hours.
Deval Abrasion Testing Machine (AIM 457) Ref. Standard IS:2386 (Part IV) The Devals Abrasion Testing Machine, AIM457 is used to determine the aggregate abrasion value of coarse aggregates as described in IS: 2386 (Part 4). The machine consists of two hollow cylinders, closed at one end and provided with tight fitting covers at the other end ...
Aggregate Abrasion Value Test (IS: 2386 (Part IV)) The abrasion value of coarse aggregate may be determined by either Deval Machine or by Los Angeles machine. Using Deval Machine . Abrasive Charge: The abrasive charge consists of 6 cast iron or steel spheres approximately 48 mm in diameter, each weighing between 390 and 445 g.
