Rheological Behavior of Recycled Fiber Reinforced Self-Compacted Concrete with Recycled Coarse Aggregate
It is known that self-compacted concrete SCC is used to serve the construction of concrete structures with complicated shapes having congested reinforcements. Sustainable SCC is produced now by recycled concrete aggregates RCA from construction wastes. To improve the strength of this concrete, with...

It is known that self-compacted concrete SCC is used to serve the construction of concrete
structures with complicated shapes having congested reinforcements. Sustainable SCC is produced now by recycled concrete aggregates RCA from construction wastes. To improve the strength of this concrete, with a further eye on sustainability, recycled steel fibers RSF is utilized as reinforcing to the SCC. In this work, 12 SCC mixes were prepared with different mixing proportions. Cement is replaced with 5% silica fume. RCA replacement percentages were 25%, 50%, and 100% RCA. RSF was used with 0.50%, 0.75% by volume of concrete. The slump flow, J-Ring, and V-Funnel tests are performed to estimate the rheological behavior of all concrete mixtures. Results indicate that RCA/RSF SCC passed the slump flow, J-Ring tests, and overpassed V-Funnel test requirements satisfactorily.
