Note 1: A procedure for testing coarse aggregate larger than mm [3 / 4 in.] is covered in Test Method C535. Thus coarse aggregates with a maximum size between 19 mm [3 / 4 in.] and mm [1 1 / 2 in.] may be tested by Test Method C535 or Test Method C131/C131M.
Jan 04, 2014· Procedure of testing Aggregate Crushing Value (ACV): 1. Make a sieve analysis and get sufficient amount of aggregate by using mm passing sieve and mm retained sieve. 2. After sieving fill the cylinder in thre layers by the aggregate and apply 25 blows by the tamping rod with a approximate height of 50 mm. 3.
This paper studied the effect of aggregate properties on the crushing strength of concrete. In order to achieve the study objective, three types of coarse aggregates, khoa, shingles stone, and black stone were used to test. And the test results show that concrete made from black stone has the highest workability followed by shingles stone khoa of aggregates.

Summary. The shelf carries them around until they drop on the opposite side of the drum, subjecting the aggregate to impact and crushing. Then, the aggregate is subjected to abrasion and grinding as the drum continues to rotate until the shelf picks up the contents, and the process is repeated.
simulates actual field conditions, but the test requires a long period of time to conduct. The "quick" checks for soundness of the aggregate are the brine freeze/thaw and sodium sulfate test. If the aggregate fails the freeze and thaw test in water, the material is tested using either the brine freeze and thaw or sodium sulfate test.
