A bulk volume of waste tires, an underrated global resource, is disposed of in landfills worldwide. Extracting recycled steel fibers from these tires is an evolving trend nowadays. Reactive-Powder Concrete (RPC), the most recent generation of concrete produced in the early 1990s and possessing extremely high mechanical strength criteria, is a modified form of high-performance Concrete. This study looked into how the type and volume proportion of new and waste steel fibers affected the compressive, flexural, and impact strengths
of RPC when it was curried at high temperatures. Steel fibers (new and waste tire fibers) with volume fractions of 1%, 1.5%, and 2% were used to create RPC. It was clear that increasing the amount of steel fiber had a beneficial effect on compressive, flexural, and impact strengths. Also, the results showed that the outcomes of RPC having steel fibers sourced from end-of-life tires are similar to those of industrial steel fibers.
