The use of recycled concrete aggregates to produce new structural concrete is a relevant solution towards the development of a more sustainable society. It is accepted as a good alternative to dumping obsolete concrete leftovers and it helps to preserve the natural aggregates’ reserves. This research sets out to limit the disadvantages associated with the performance of concrete with several replacement ratios of fine natural aggregates (FNA) by fine recycled concrete aggregates (FRA) by using two superplasticizers, which differ mainly in the water reduction capacity and robustness. The workability, density and compressive strength of each of the mixeswas analysed and then compared.
