Abstract:

Concrete compressive strength is one of the most important criteria affecting various parameters. Therefore, changing or optimizing the effective parameters in the manufacture of cement mortar can lead to lower costs and increase compressive strength. In this research, the effect of each compressive strength parameter has been studied considering three factors: water to cement ratio, Fine grained to cement ratio and the amount of Nano-silica used in cement mortar. In this method 18 laboratory samples were used and the effect of three parameters mentioned at the following levels on the cement mortar by Taguchi optimization method are investigated: the ratio of water to cement at 0.35, 0.4, 0.5 levels, fine-graind to cement at 2, 2.5 levels, and the amount of Nanosilica of levels 4.5, 9 and 13.5. By examining the interactive behavior of the three parameters provided by the Taguchi method, it has been found that the optimal amount of water to cement ratio is 0.35, cement is to cement ratio 2, and the amount of Nano-silica used in cement mortar 13.5. Finally, considering the scope of this method in previous research and results, the Taguchi statistical method can be used as a reliable method.
