    The present study explores the influence of tire rubber aggregates on Portland cement mortars. The rubber aggregates were obtained by mechanical grinding of waste automobile tires, and introduced in the mixtures as partial replacement of sand at four different levels by volume: 5, 10, 15 and 20%. Workability, density, flexural and compressive strengths, apparent porosity, ultrasonic pulse velocity and the dynamic modulus of elasticity were studied for each mortar mixture and the results obtained were then compared to those of a control mortar. Test results showed that modified mortars were lighter, had better deformability and better sound insulation properties than the control mortar. However, rubber aggregates caused a decrease in compressive and flexural strengths and workability, and a slight increase in apparent porosity. The mortar containing 10% of rubber aggregates was the most promising as it combined the beneficial effects of rubber aggregates (lightness, deformability, sound insulation), while the workability and apparent porosity were almost constant, and the decrease in mechanical strength was contained. Considering technical and environmental aspects, the rubber modified mortars offer a range of possible applications that could bring partial solutions to the waste tires issue, but also to sand exploitation related issues. - COLLAPSE
