Abstract: Starting from the fact that the exploitation of quarries has serious environmental impacts through their emission of dust and fine sands which are dispersed in nature, and in an ecological and sustainable approach, in this article, we propose a study allowing their recycling and valorization, in the manufacture of earth blocks reconstituted for a possible use in the constructions. The produced samples have been made according to the proportion’s addition of (0%, 10%, 20%, 30%, 40% and 50%) with quarries waste aggregates. They were hardened and tested in order to study the influence of these additions on the behavior of the compressive strength. Another formula seeking an optimized mixture according to the compressible packing model where highest resistance was also tested. The results showed that for a substitution greater than the optimized formulation, the compressive strength decreases.
