Abstract

The most flexible and resourceful material is Concrete. It is mainly because of the high and tenacious demands of concrete. By using advanced chemical admixtures and additional cement oriented resources like fly ash, silica fume, granulated blast furnace slag and more, Engineers have been incessantly pushing the limits to increase the performance of Concrete. Large amount of the usage of cement yields increasing emissions of Carbon dioxide (CO2) resulting in the greenhouse effect. Using silica fume, a non-crystalline polymorph of silicon dioxide in concrete mixtures is a method that helps in reducing the content of cement. One of the most favorable and hopeful zones of science is Nano technology. The usage of Nano materials such as Nano silica, Nano alumina, Nano titanium oxide and Carbon Nano tubes in concrete is a new revolution. These materials greatly amend the strength properties of concrete. The present study aims at such strengths like Compressive, Flexural and Split Tensile of M40 grades of concrete along with usage of micro silica (5%, 7.5%, 10%, and 15%) and Nano silica (1.5%, 2%, and 2.5%) as partial replacement of cement.
