The test is not applicable to material passing a 6.30 mm test sieve or retained on a 63.0 mm test sieve. The flakiness index was determined according to the procedure given by BS 812: Part 105-1. The results are given in Table.3. As seen in this table, the flakiness index of the basalt aggregate is 25%.

· Aggregates: As coarse aggregates, natural crushed stone and recycled coarse aggregates (RCA) are used in this test. Fine aggregates are natural river sand. The effects of RCA on the property of concrete are not consistent since each RCA type has a different composition and the quality is different from each other [29] .
