Abstract:

Self-Consolidating Concrete (SCC), also known as self-compacting concrete, is a type of hydraulic cement concrete that easily forms around the reinforcement without segregation. The use of recycled fibers in the SCC mix, affect the compressive strength, tensile strength and crack initiation and propagation. The main objective of this study was to investigate the application of novel-fibers reinforcement SCC in transportation infrastructures. The improved mechanical properties of the modified SCCs make them alternative solutions for precast sections for transportation infrastructure applications compared to the conventional concrete. In the first part of this research, the effect of six fibers on SCC properties was investigated and in the second part the hybrid effect of fibers was assessed. According to the results, each recycled fibers has the capability to improve targeted properties whereas the binary combination of fibers has the potential to improve wider range of properties.
