Influence of Colloidal Silica and Partial Replacement of Cement with Metakaolin in Concrete

High strength concrete is being required due to the construction industry's growth. Admixture and supplemental cementing materials (SCMs) are employed attain this strength. According earlier research, nanoparticles with a high surface area volume ratio, such as colloidal nano-silica (CS), which contains an amorphous silicon dioxide (SiO2) core hydroxylated surface, have potential for extremely chemical reactivity. This study examined results of adding metakaolin silica in varying amounts. Tests accordance Indian standards been conducted order evaluate compare mechanical properties concrete, compressive strength, split tensile flexural while employing different percentage replacements silica. norms, 150mm cubes were cast tests diameter by 300mm height cylinders produced tests. In investigation, was used instead 10 30 percent cement mass, 0 6 added. The experiments indicate that most optimal mixture, desirable obtained, 10% 2%
