Experimental Study on Nano Silica Concrete

International Journal for Research in Applied Science and Engineering Technology, 2023
Abstract: Concrete is the most common material for construction. The total production depends upon the cement content only. Due to the usage, large amount of cement produces increasing the CO2emissions, to reduce the cement percentage in concrete mixes the nanosilica (nSiO2) is used as the replacement of the cement. The application of nanotechnology to
