| dc.description.abstract | The growing demand for sustainable construction materials and effective waste management
has encouraged the utilization of industrial and solid wastes in concrete production. Waste
tire rubber, generated in large quantities worldwide, poses serious environmental challenges
due to its non-biodegradable nature. This study investigates the strength and durability
performance of sustainable rubberized concrete by partially replacing natural fine and coarse
aggregates with tire powder and tire chips. Several concrete mixes were prepared with
varying replacement ratios, and their mechanical properties were evaluated through
compressive strength, split tensile strength, and flexural strength tests at different curing
ages. In addition, durability characteristics such as water absorption, permeability, and
resistance to aggressive environmental conditions were examined. The experimental results
indicate that increasing the rubber content leads to a reduction in mechanical strength
compared to conventional concrete; however, rubberized concrete exhibits improved
ductility, energy absorption capacity, and crack resistance. Within an optimum replacement
range, the durability performance of rubberized concrete remains satisfactory. The findings
demonstrate that the incorporation of tire powder and tire chips in concrete contributes to
sustainable waste management while producing an environmentally friendly construction
material suitable for non-structural and selected structural applications. | en_US |
