The objective of this paper is to study the properties of different compositions of concrete made by substituting sand made of crushed limestone, which is over-exploited in Algeria, by two types of sands produced by the recycling of double-layer tiling and granite waste, respectively, with different mass percentages of 0, 10, 20 and 30%. The physical, mechanical and some aspects of the durability properties of six concretes were evaluated and compared to those of a reference concrete. The results obtained show that the incorporation of granite sand up to a rate of 20% improves the compressive strength and the resistance to acid CH3COOH. For concretes made with tiling sand, the best compressive strength was observed in concrete with an addition rate of 10%. Furthermore, good tensile strength by splitting is obtained with rates of up to 30% of the two recycled sands.
