2008-11-3  single source of commercially graded unwashed coarse RCA and natural fines was used in all recycled concrete mixes. The natural coarse aggregate used in the reference mixes was a nominal 14 mm crushed basalt. The grading of the basalt and the coarse RCA conformed to the requirements of AS 2758.1 (Standards Australia 1998), as shown in Table 1. A fine to coarse aggregate ratio of 46:54 was kept constant throughout the test program for all concrete mixes. The RCA was batched in the as-received state. Details of the physical properties of both aggregates
