The test aims at looking for the forces required to produce 10 of fine values ie weight of fines aggregates/weight of all aggregates = 10 This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value AGGREGATE CRUSHING VALUE AND TEN PERCENT Aggregate crushing Value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Ten Percent Fines Value used for testing aggregate smaller than 10 mm Comprises 150 mm or 75mm diameter steel chat online
