The application of Nanotechnology in concrete has added a new dimension to improve its properties. Nano-materials. by virtue of their very small particle size can affect the concrete properties by altering the microstructure. In this study an attempt is made to analyze the effect of Nano-Silica on the strength of control concrete and replaced cement concrete. In replaced cement concrete. cement is partially replaced with the dolomite powder and fine aggregate with granite fine in different percentages. Workability and Strength tests were conducted on both the control concrete and concrete with Nano-Silica. dolomite and granite powder. The replace percentage of dolomite powder 15% and 20% of granite fine gave good results. more than this percentage of mix the strength of concrete decreased. Nano-silica of different percentages 0%. 0.5%. 1%. 1.5%. 2%. 2.5% and 3% added to this selected mix (15% DP and 20% GP) and control concrete. The test results reveal that the replacement of Nano-silica from the replacement percentage of 0.5. the strength of concrete significantly increases with increasing percentage of Nano-silica upto 2.5%. The Cost of the replaced concrete increased as well as the strength also with reference to control concrete. However this is valid upto certain point. later the strength decreases with increase in cost.
