Characteristics of concrete using recycled rubber

The construction industry faces challenges with waste and carbon emissions. One proposed solution is adding engineered rubber from worn tires into concrete. This chapter discusses the properties, production methods and uses of rubberized concrete (RC). Compared to regular concrete, RC is more flexible, has higher impact strength, better thermal insulation and improved sound absorption. However, it has lower compressive and tensile strengths. These strength reductions can be minimised by optimizing rubber content, particle size, surface treatment and mix design. The performance of RC is affected by permeability, durability and specialized concrete mixtures such as rubberized pervious concrete (RPC), self-compacting RC and rubberized roller-compacted concrete. The chapter describes testing methods, including materials, mixing and key characteristics of RC. It explores potential applications of RC in road construction, sound barriers, building materials and sustainable construction techniques. It also considers environmental and economic impacts like waste reduction, CO2 savings and life cycle costs. Additionally, it discusses the obstacles and challenges of these practices and suggests strategies to overcome them. This article serves as a comprehensive review of the use and limitations of RC in sustainable construction.
