Flexural Behavior of Sustainable Concrete Beams Containing Waste Tire Fibers and Recycled Aggregates

Abstract: The increasing accumulation of diverse waste materials poses a significant societal challenge, highlighting the importance of developing methods to reuse such waste effectively. One promising solution involves incorporating recycled coarse aggregate (RCA) obtained from demolished concrete into new concrete mixtures. Additionally, tire-derived fibers (TDF), sourced from recycled tires, present an environmentally friendly substitute for conventional reinforcement materials. The integration of RCA with TDF in reinforced concrete beams offers a sustainable approach to enhancing structural performance. This experimental study investigates the flexural performance of reinforced concrete beams containing recycled coarse aggregate (RCA) and tire-derived fibers (TDF). Four mixes with varying RCA (0%, 25%) and TDF (0%, 0.75%, 1.5%) were tested. Four full scale beams were tested in flexural. Results show that replacing 25% of natural aggregate with RCA maintains strength and structural performance, while adding TDF improves flexural strength, mechanical properties, ductility, and load capacity
