Tire-Derived Aggregate Cementitious Materials: A Review of Mechanical Properties

This chapter presents an overview of tire-derived aggregate concrete, also known as rubberized concrete, a cementitious-based material with some or all of its mineral aggregates replaced with rubber particles. Typical source of rubber materials is scrap tire. Tire- derived aggregate concrete has practical applications as safety barriers, sound barriers, and architectural features among others. General observed trends include a decrease in compression strength, a decrease in flexural strength, and an increase in energy absorption and damping capacities with an increase of rubber content. These characteristics are modifiable by application of lightweight aggregates, fiber-reinforcement, admixtures, and other common techniques. The chapter also includes discussions on handling, design, and analysis of tire-derived aggregate concrete.
