The effects of recycled aggregates on the properties of fresh self-compacting mortar are not well known. An experimental study was undertaken to find out the effect of substitution of either 100% or 50% of natural aggregates by recycled concrete aggregates on the fresh properties of the SCC. The results have shown that the substitution of 50% or 100% of natural aggregates by recycled concrete aggregates gives SCC with very comparable workability to that of the reference SCC. However, SCC with recycled aggregates are less stable against bleeding. The addition of slag improves workability for SCC with natural aggregates but it leads to a decrease of workability for the SCC with recycled aggregates.
