Abstract Utilization and reuse of waste rubber tires in concrete leads to sustainable construction. There are number of studies that have been conducted on concrete with rubber as aggregate in order to maintain mechanical properties and durability of material. Contrary, only several studies have been conducted on usage of waste rubber tires as aggregate in reinforced concrete elements and systems. These review paper summaries and compare independent research works and justifies weather these aggregates are possible to utilize improved behavior of concrete elements or not. According to general conclusions on fundamental properties of rubberized elements it is evident that the waste rubber tire aggregates can be used as partial replacement of both coarse aggregates and fine aggregates. Previous research on structural elements shows that replacement of the natural aggregate with recycled tire aggregate in concrete, will produce structural elements with improved behavior: increased capacity for deformations (ductility), better dissipation of energy, and higher damping, in comparison with standard concrete made with conventional aggregates. However, the increased content of rubber in concrete also has negative effects, for example reduction of compressive and tensile as well as reduction of Young's modulus of elasticity. The results of these experimental studies are not sufficient to reach a general consensus on the application of recycled rubber in concrete and its effect on the behavior of structural elements. Inconsistency of the effects of recycled rubber in the concrete on the static and dynamic properties of reinforced-concrete structures indicate that there is uttered need for further research.

• A comprehensive review on the mechanical properties of waste tire rubber concrete (2020, unknown): “Although, there have been a few review papers published in the past that cover the effect of some rubber treatment methods on the mechanical and durability properties, they do not cover all the treatment methods and all of the mechanical and durability properties studied so far [68–74].”
