The samples and the ball charge are considerably smaller than those used in the LA abrasion methods and are not subjected to significant impact forces. The results of the test are more focused on durability and abrasion resistance. ASTM methods for testing coarse and fine aggregates are found in D6928 and D7428. Other variations of the test ...
Grinding uses fixed abrasives—the abrasive particles are bonded to the paper or platen—for fast stock removal. Polishing uses free abrasives on a cloth; that is, the abrasive particles are suspended in a lubricant and can roll or slide across the …
After grinding to pass 100-mesh sieve each was treated with 1 percent hydro chloric acid at room temperature for 30 minutes, filtered, and washed with water to remove any sulfate that may have been present due to oxidation. Each sample was then dried with acetone, and placed in an airtight bottle. These
