Abstract

A push for increasing the lifespan and sustainability of infrastructure has led to a need for more durable, strong, and environmental friendly construction materials. A concrete mix design using recycled steel fibers from rubber tires was chosen to enhance the mechanical properties, durability, and sustainability of the concrete. Concrete mixtures with different quantities of recycled and manufactured steel fibers were examined. Compression and flexural tests were performed in order to analyze these properties and used to compare the results with the industry standard steel fibers. The results show the flexural strength and toughness of fiber reinforced concrete has increased compared to reference mixtures and comparable results to manufactured steel fibers. It is found that the recycled fibers present an environmental friendly option to reduce tire waste in landfills and present a cheaper option than the industry used steel fibers.
