Behavior of composite self-compacting concrete (SCC) reinforced with steel wires from waste tires

Abstract

Large amount of waste tires are generated progressively every year. Therefore, many researches have been conducted on using recycled tire products in several civil engineering products. This paper is focusing on feasibility of using recycled steel fibers from waste tires as reinforcement in functionally graded self-compacting concrete (SCC). Firstly, fresh and hardened properties of the normal and steel fiber reinforced concretes were investigated. After obtaining the mechanical properties of steel fiber reinforced SCC, 16 multi-layered beams were tested under 4 point bending test by considering various fiber fractions and layer thickness. Additionally, SEM images were used to maintain the failure mechanisms between steel fibers and concrete matrix.
