Abstract: The incorporation of rubber waste from tires into cementitious elements has become an increasinglyrecurrent practice, since this activity fosters the idea of sustainable construction. The use of rubber asan aggregate in the mortar promotes the correct destination of this residue, becoming inert, promotingthe hygiene of the environment. Many researchers have studied the physical and mechanical behaviorof rubberized mortar. However, particle geometry analyzes are scarce. This research aims to study theincorporation of rubber tire residues in mortars in two grades of granulometry, i.e., spheroids (S) andfibers (F), replacing the conventional aggregate in 7.5%, 15% and 30%. Density, compressive strength, flex-ural strength, microstructure and sound attenuation tests were performed. Rubber mortars showed areduction in density of up to 34.6% compared to conventional mortar, consequently resulting in a reduc-tion of approximately 4 times in compressive strength. However, there is a better acoustic behavior, espe-cially when the rubber is used in fiber format, which presents 29.70% and 42.54% of attenuationenhancement for 15% of fiber waste tire rubber, considering P- and S-waves, respectively
