Abstract
In the construction industry, the use of fibers to improve the mechanical properties of concrete has been a focus of attention in the past decades. Among the various types of fibers, steel fibers have been widely used as an additive in concrete due to their unique properties, strengthening and increasing the strength of concrete. However, the mass production of these fibers is accompanied by significant CO₂ emissions and leads to a depletion of natural resources. The accumulation of huge amounts of used tires worldwide is a serious challenge for the environment. Recycling these tires, and especially the extraction of steel fibers from them, has been proposed in recent years as one of the new approaches towards sustainable development and the use of alternative materials in the construction industry. Various studies have shown that concrete containing recycled steel fibers from used tires (Waste Recycled Tire Steel Fibers – WRTSF) has properties similar to concrete reinforced with industrial steel fibers. In this study, an integrated approach including scientometric analysis and systematic review of experimental studies was used, so that the results of the research trend analysis were the basis for organizing and analyzing the mechanical behavior of concretes containing WRTSF. The findings show that the use of this type of fiber, in addition to reducing environmental waste, improves toughness, crack propagation resistance, and durability of concrete. Finally, solutions are presented for selecting the optimal composition and amount of WRTSF in various civil engineering applications such as pavements, bridge decks, tunnel linings, and hydraulic structures.
