Abstract Recycled aggregates contain a high percentage of fines with diameters < 63 μm due to the crushing and grinding of the source concrete. These fines contain a proportion of non-hydrated cement that can interact and act in concrete in the presence of water. To this end, a substitution of Portland cement by recycled fines (RF) with the following percentages 5%, 10% and 15% was carried out, thus studying their effect on concrete based on alluvial sand (AS) and recycled sand (RS), with two proportions namely: 85% AS + 15% RS and 75% AS + 25% RS, to assess the impact of using recycled aggregates (recycled sand (RS) and recycled fines (RF)) from demolition waste on the properties of recycled sand-based sand concrete and alluvial sand on physical properties, including workability, weight loss, bulk density and porosity of alluvial sand concrete. This study is part of sustainable environmental protection. The results obtained show noticeable improvements of the properties studied, sand concrete based on 85% AS + 15% RS with 10% RF gives the best results
