The current study is focused on gaining optimum concrete mixture design which contains nano-silica or mirco-silica, by employing different evaluation factors such as water to the cement ratio, cement grade and different age of investigation (7 and 28 days), using a robust predictive method that is called Taguchi. Nine mixture designs are optimized by Tguchi method to achieve maximum compression strength, maximum bonding strength between concrete and rebar and minimum water absorption. Obtained mixture designs are then employed in the laboratory and the results are investigated for the optimization process. In this study the XRD test is used in addition to mechanical concrete tests and permeability test in the macro scale. Obtained results show the reliability of the Taguchi method in the prediction of the concrete mixture design.
