Assessment of Galvanized Iron Fiber and Waste Tire Composite Concrete

Abstract

The traditional method of disposing of tire debris is now a huge worldwide problem and presents serious environmental risks. Because of this, using waste tires in concrete not only lowers its density but also guarantees an economical and environmentally responsible alternative for the building sector. However, because of their superior ductility and tensile strength, galvanized iron (GI) wire fibers are now more frequently used in plain concrete. Different amounts of waste tire fiber (WTF) with different coarse aggregate replacement ratios (0, 3, 6, and 9%) and different percentages of GI fiber (GIF) (0, 1, 3, and 5%) of concrete volume were examined in this study under axial compression in concrete grades M25, M30, and M35 respectively. According to the test results, GI fiber and waste tire composite concrete demonstrated ductile failure behavior in comparison to control concrete, in addition to delaying the propagation of cracks. On the other hand, the workability of concrete decreased as the percentage of mixed fiber increased. In addition, higher-strength concrete’s ductility and compressive strength considerably improved as fiber percentages rose in comparison to lower-grade concrete. The specimen that contained 1% GIF and 3% WTF performed the best under peak load conditions for higher-strength concrete, according to the data.
