Rubberized Concrete and Strategies for Improving Its Durable Properties - A review

Abstract

Globally, the disposal of used tires is a major environmental concern, creating difficulties such as mosquito breeding grounds, igniting uncontrolled fires, and poisoning soil and vegetation. Therefore, alternative outlets for these tires are urgently required, with a concentration on tire recycling. Concrete is an excellent building material that is believed essential for modern civilization and human society. The utilization of recycled tires in concrete is now technically feasible. However, substituting rubber for concrete will drastically alter its mechanical and durable properties. Even if there is a reduction in the mechanical properties and durability properties of rubber concrete, this may be overcome by increasing its adherence by treating the aggregates. To improve the adherence of rubber aggregates, with physical, mechanical, chemical, and thermal treatments may be utilized. Under the rubberized concrete, the majority of studies collected data on mechanical qualities. Regarding durable properties, data collection is fairly less. This analysis aims to accomplish that objective by examining the qualities of rubberized concrete and the strategies for overcoming the challenges associated with rubber concrete’s durability attributes. This study reviews water absorption rate, water permeability, chloride penetration, carbonization, Alkali-Silica reaction, and freeze throw resistance, and how to overcome some negative results by various kinds of treatment methods. This paper is intended to stimulate the use of rubberized concrete in infrastructure development and serve as a foundation for future research on this material. The usage of rubber concrete will result in the sustainable utilization of waste material, protecting the environment and conserving sources of diminishing natural aggregates.
