Assessment compress strength of high-performance concrete with variable content of nano silica by one-way anova and tukey’s method

Nano-silica is increasingly proving its features in the manufacture of high-performance concrete. Incorporating nano-silica into the mixture to improve the mechanical properties of concrete has become a field of interest. A very high surface area characterizes ultrafine Nano Silica particles to mass ratio and active ability. In addition to tightening the structure, nano-silica also activates the cement’s increased pozzolan reactions. The pozzolanic reactions help eliminate the unstable components in concrete (calcium hydroxide), producing gel products with better quality than before. Therefore, the experimental results were evaluated by one-factor variance analysis and posthoc analysis by Tukey’s test to clarify further the effect of nano-silica levels with a range of from 0% to 3% of the total weight of adhesive to the compressive strength of high-strength concrete at 28 days of age and results shown that a nano-silica ratio of 1.5% shows the most suitable value by Mininitab19 softwar
