Construction aggregates lay the foundation and create the infrastructure of our cities and towns. Sand, gravel, and limestone are key ingredients in concrete, asphalt, and base material, which are the building blocks for highways, bridges, public utilities, airports, schools, churches, office buildings, houses, golf courses, football stadiums, and much, much more.

The improvement of the mortars based on dune sand was made through the addition of crushed wastes of ceramic tiles and red clay brick. The formulation of mixtures is based on the substitution of dune sand with crushed wastes at different weight contents; 5, 10, 15, 20 and 25%. The W/C ratio is fixed at 0.7.

10% of the quantity of crushed sand. This perceived risk associated with crushed sand together with the lack of data has contributed to skepticism and the reluctance to use crushed sand. It also led some aggregates manufacturers to invest on costly processing equipment to screen off or remove the fines (Benabed, 2012; Gschaider, 2001).
