The method is not suitable for testing aggregates with an aggregate crushing value higher than 30, and in such cases the method for ten per cent fines value described in BS 812-111 is .

The RCAs, coded new recycled concrete aggregates (NRCAs), were obtained from crushing a batch of new concrete produced by a ready-mixed concrete supplier after 6 months of outdoor curing. The crushed NRCAs were further sieved into three size fractions: 10–20, 5–10, 2.36–5 and <5 mm.

May 05, 2010· Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

Feb 15, 2019· Aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The aggregate crushing value should not exceed 45% for aggregate used for concrete other than for wearing surfaces, and 30 % for concrete for wearing surfaces, such as runways, roads for pavements.

The RCAs, coded new recycled concrete aggregates (NRCAs), were obtained from crushing a batch of new concrete produced by a ready-mixed concrete supplier after 6 months of outdoor curing. The crushed NRCAs were further sieved into three size fractions: 10–20, 5–10, 2.36–5 and <5 mm.
