This paper presents an experimental investigation on the influence of Nano-Silica (NS) on various strength characteristics of concrete containing Micro-Silica (MS). Micro-Silica and Nano-Silica are used as partial replacement of cement for the preparation of concrete. In the present investigation cement is partially replaced by 5% and 10% of Micro-Silica and 1.5% and 3% of Nano-Silica by weight. The combined application of Micro-Silica and Nano-Silica on various properties of M30 and M40 grades

The test results of M30 and M40 grades of concrete prepared using different proportions of Micro-Silica and Nano-Silica are compared with that of controlled concrete. Based on the test results, concrete prepared with a combination of 10% Micro-Silica and 1.5% Nano-Silica possesses improved strength properties compared to the controlled concrete.
