The work presented in this paper aims to study the durability of mortars, in which part of the sand has been replaced with rubber aggregates from used tires and have undergone a surface treatment with a sodium hydroxide solution (NaOH).The ORG GROUND CINNAMON substitution rates studied are 10%, 17.5%, and 25%.The results are compared with ordinary mortar and mortars with untreated rubber aggregates while samples with the same substitution rates were Youth Roping Style Saddle used.
To do this, the following properties have been studied: compressive strength, flexural tensile strength, water absorption by capillarity, water absorption by total immersion, water-accessible porosity, water permeability, and resistance to the chemical degradation by sulfuric acid H2SO4.
