The aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate. The strength of coarse aggregates is assessed by aggregates crushing test. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. Get Details; Exp 4 Aggregate Impact Value Civil Engineers PK. .
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.
