| Summary: | Concrete production has a considerable impact on global greenhouse gas emissions owing to the energy-intensive manufacture of cement and steel. Using Waste Tire Recycled Steel (WTRS) fibers is a more sustainable alternative to industrial steel fibers, addressing both environmental pollution and waste management issues. This study investigates the microstructural and mechanical properties of WTRS fiber-reinforced concrete, offering useful insights for the construction sector. Concrete specimens with 1.5% WTRS fibers by volume were created with the goal of achieving a compressive strength of 35 MPa. Microstructural examination was performed using scanning electron microscopy (SEM), as well as mechanical testing such as compressive, flexural, and tensile strength measurements. WTRS fiber-reinforced concrete outperformed conventional concrete in terms of compressive strength (69.7 MPa), load-deflection, and ductility. However, the tensile and flexural strengths were lower than those of traditional steel-reinforced concrete. WTRS fibers boost compressive performance, but additional modification of fiber characteristics is required to improve energy absorption and flexural strength. This study highlights WTRS fibers’ potential as a sustainable reinforcing material, as well as the importance of long-term environmental and performance evaluations. |
