— Concrete composite is one of the main construction materials in civil engineering, with large quantities of itbeing consumed all over the world each year. Cement is an important raw material in the production of concretecomposite. During manufacturing of cement, large amounts of carbon dioxide (CO2) get into the atmosphere. So, it isrequired to use a Green concrete that will result in the sustainable development without destruction of natural resources.The major objective behind green concrete is to reduce CO2 emission from cement industry. The application ofnanotechnology in concrete has added a new dimension to the efforts to improve its properties. Nanomaterials, by virtueof their very small particle size can affect the concrete properties by altering the microstructure. This study concernswith the use of nano silica to improve the compressive and tensile strength of concrete. An experimental investigation hasbeen carried out by replacing the cement with nano silica of 2.0%, 3.0% and 4.0% by weight of cement. The testsconducted on it shows a considerable increase in compressive and tensile strength of concrete. The strength increase wasobserved with the increase in the percentage of nano silica.
