Abstract
Self-compacting concrete (SCC) has become widely used thanks to its various advantages. SCC is also fiber reinforced, similar to conventional concrete. However, studies on SCC with fiber addition are limited. In this study, the effect of basalt fibers at different aspect ratios on the mechanical and workability properties of SCC was examined. Slump flow, V-funnel, compressive, flexural and splitting tensile strength tests were carried out within this study. Results showed that, although increasing the aspect ratio causes improvement in the workability properties of concrete, workability decreases compared to the reference SCC. Increases were observed in flexural and splitting tensile strengths with increasing aspect ratio. The compressive strength of the specimens that contains BF decreased compared to the reference sample because of the agglomeration effect. The results obtained were examined and discussed in detail.
