The deterioration of marine concrete structures due to corrosion damage is increasingly recognized as a serious worldwide challenge for researchers and managers in both technical and economic terms while also leading to other adverse factors. The cost of repairing corrupted and destroyed structures is enormous. The issue of how to improve durability in concrete has received considerable critical attention. There have been several reported longitudinal studies involving the durability of concrete. However, there has been little quantitative analysis of improving the durability of concrete in the seawater environment by incorporating additives. Thus, the aim of this study is to shine new light on using the Taguchi method, which is assisted by MINITAB 19 software to find out the appropriate mixing parameters between some main additives, including fly ash, silica fume, and additive reducing water changing with three levels. The effect of each parameter is evaluated based on the signal-to-noise (SN) ratio: compressive strength is analyzed according to the more significant criterion, while other indicators of durability such as absorption, permeability coefficient, and abrasion are less important. The study offers some important insights into the results of experiments showing the application of the Taguchi experimental method, which allows us to determine the reasonable percent of the additive components with the least number of tests.
