Resumen
We study the behavior of mortars where 0%, 10%, 20%, 30%, 50% and100% of their original natural sand was replaced by ceramic sand in asearch of potential new building materials that will help to conservenatural resources and that are environmentally friendly. In this paper, thephysical properties of the sands and their derived mortars, including theircompressive strength, flexural strength, and shrinkage due to base andtotal drying, are characterized. Our results show that the compressiveand flexural strengths of the recycled mortars decrease proportionallyto the amount of natural sand replacement used. A similar behavior isobserved for the shrinkage due to drying in mortars with low ceramicsubstitutions (10%, 20% and 30%). Based on these findings, we believethat the use of mortars made with recycled sand (with substitutioncontents lower than 30%) could be feasible in applications where themechanical requirements are low.
