- Previous studies have proven that self compacting concrete and fibre reinforced concretes are more suitable and efficient in concrete technology. Hence, the current study is aimed at investigating the effects of hooked end and crimped steel fibres on the performance of fibre reinforced self-compacting concrete with RCA and foundry sand (RCA-FR-SCC). In the present study tests for rheological properties were performed. Totally 20 mixes with RCA of 0, 25, 50, 75 percentage of Natural Coarse Aggregate (NCA), and three different combinations of reinforcing hooked end and crimped steel fibers and 15% of optimum replacement of foundry sand. The results of the study have proven that the addition of fibres with both RCA and foundry sand in optimum percentage, can significantly improve rheological properties of RCA-FR-SCC.
