This study aims to evaluate the effect of waste rubber tire replacement on bulk density, flexural strength, and sound absorption coefficient, while identifying the optimal percentage for the desired characteristics. The experiment varied the rubber tire content (5%, 10%, 15%, 20%, and 25%) as the independent variable, with specific gravity, flexural strength, and sound absorption as the dependent variables. The results show that increasing the percentage of waste rubber tires will decrease the concrete density, with a minimum concrete density of 1311.63 kg/m³ at 25% replacement. However, higher tire content will weaken the flexural strength, which peaks at 3.02 N/mm² at 5% replacement. On the other hand, the acoustic performance improves with more rubber content, reaching optimal sound absorption at 15% replacement, with a maximum coefficient of 0.22324 at 974 Hz.}, issn = {25496778}, doi = {10.14710/mkts.v30i2.65498}, url = {https://ejournal.undip.ac.id/index.php/mkts/article/view/65498} }
