ABSTRACT

The two most important attributes of concrete are strength and durability. The concrete durability crisis has attracted and compelled engineers to focus on concrete performance. Considerable research and attention go into creating reinforced concrete buildings, which face challenging surroundings and are intended to last for a prolonged period of time with minimal maintenance. To accomplish this requirement, one material that has attracted a lot of attention is Nano material combined with SCM's. The researchers looked at partial cement replacement with Metakaolin levels of 10, 20, and 30% and Nano Silica levels of 1.5, 3.0, and 4.5 percent by weight of cement in this study. W/B ratios of 0.3, 0.35, and 0.4 were used with A/B ratio of 1.75. Cubes were cast for different mix proportions and immersed in 5% concentrated HCl, H₂SO₄, and MgSO₄ solutions for 30, 60, and 90 days. The residual compressive strength obtained after 30, 60, and 90 days of immersion in different acid solutions were compared to controlled concrete. According to ongoing research, concrete prepared with a combination of 10% Metakaolin and 3% Nano silica is the best for achieving the highest durability properties in concrete and improving its performance.
