dc.description.abstractApplications utilizing rubberized concrete have grown substantially in the last decade as an answer for the scrape tires stockpiling problems and its associated environmental issues. Though rubberized concrete mixtures generally have a reduced compressive strength and stiffness that may limit their use in specific structural applications, they possess several desirable properties such as lower density, higher toughness, and better dampening ability resulting in an enhanced dynamic performance. The purpose of this study is to investigate the effect of using recycled Tire Derived Aggregates (TDA) to partially replace coarse aggregates in concrete mixtures. Natural coarse aggregates in the considered concrete mixtures was partially replaced by 10%, 20%, and 30% of TDA. The specimens were tested under uniaxial compression up to failure. The results showed a decrease in the compressive strength and the elastic modulus of the concrete as the replacement ratio increase. It was observed that increasing the content of TDA to 30% of the coarse aggregates by volume decreased the compressive strength and elastic modulus of the concrete by 36% and 17%, respectively. This is a research in progress and more results on higher content of TDA will be provided later.en_US
