SELF COMPACTING CONCRETE WITH NANO SILICA FINES

Nano technology has become a rapid industrial revolution of 21st century .it will affect almost every aspect of life. As concrete is generally used material for construction. By adding silica fumes in concrete in order to decrease the cement content in concrete mix, we can control large amount of co2 emissions from constructed structures. We use nano silica fumes i.e., 10-50 nm size fumes. This research is on the experimental point of view. It aims to find the performance of nano silica in concrete mix. To obtain concrete with better properties and to decrease the harm to environment we are using replacement of cements with different percentages and hence obtain the results.
