This article presents the results of determining the mechanical properties of rubber concrete produced using crumb rubber from waste tires instead of fine aggregate. The tensile and flexural strength of rubber concrete with different amounts of crumb rubber were investigated. The mechanisms of crumb rubber influence on concrete strength were analyzed. The results showed significant differences: with an increase in rubber content from 0.0% to 20.0%, the compressive strength of rubber concrete decreased from 26.45 MPa to 14.8 MPa, respectively. It was also found that changes in the concrete void structure due to the introduction of crumb rubber significantly affect its mechanical properties. The results of this study fill an important gap in the analytical evaluation of rubber concrete, contributing to its application in sustainable construction practices.
