Review of Research Progress on Rubber Concrete

Abstract

 As an environmentally friendly material, rubber concrete has attracted widespread attention from researchers around the world due to its lightweight, superior ductility, strong impact resistance, thermal insulation and sound insulation, especially in the utilization of waste tires. Produces significant economic and environmental value. In recent years, research on the mechanical properties of this material has been in-depth, revealing that although the replacement of traditional aggregates by rubber may lead to a decrease in the strength of concrete, scientific means, such as aggregate surface modification to enhance the bonding strength with the cement matrix, or adjust The ratio of water to cement in the mixture can effectively make up for this deficiency. In addition, the low water absorption and lightweight structure of rubber concrete itself complies with the application standards of lightweight aggregates, further confirming that converting waste rubber into building materials is not only feasible in theory, but also an effective strategy in practice.
