The different steps involved in abrasion testing for aggregates as per IS: 2386 (Part IV) 1963 are as follows: Step 1: Consider a specified amount of aggregate (5 kg), which is larger than mm size. Step 2: In this test we should consider charge balls (as per table 1) of specific weight which depends on the grading of aggregate.
Wet Ball Mill Tex116E. The Rainhart Aggregate Wet Ball Mill is used to determine the resistance of aggregate in flexible base materials to disintegration in the presence of water. These results are essential in determining whether the base will resist crushing, degradation, disintegration, and premature structural failure.
