The influence of nano-silica (NS), carbon nano-tube (CNT) and fly ash (FA) as solo, binary or ternary combination on fresh and hardened properties of self-compacting concretes (SCC) were investigated in this study. These materials were replaced with the certain portion of the cement. In scope of this study, the eight groups of mixes categorized into two categories with and without FA so that each category possessed a reference group and three other groups with only NS, CNT or both. Based on different previous studies, the optimum substitution percentages selected 2%, 0.08% and 40% for NS, CNT and FA, respectively. The slump-flow, V-Funnel and L-Box properties of the produced fresh concretes were investigated. Besides, compressive strength and flexural toughness properties of hardened concretes were determined and were compared with typical properties of SCC.
