Dec 30, 2017  Natural and recycled aggregates content (vol%) in the investigated self-compacting concrete mixes. A concrete mix, named R25, was obtained substituting 25 vol% of natural aggregates (coarse and fine) with recycled aggregates. R25 contains 45 vol% of N0-6, 30 vol% of N6-16, 12 vol% of R0-4, 5 vol% of R4-8 and 8 vol% of R8-16.
