Enhancing properties of concrete by using Nano-Silica as a partial replacement of cement

Civil Engineering

Concrete is most commonly used construction material and it consumes huge amount of cement. Manufacturing of cement produces increasing CO2 emission which is harmful to the environment. Method used to reduce cement content in concrete is use of nano- Silica and Fly ash partial replacement of cement in concrete. Nanotechnology is one of the most promising areas of science. The use of nano- material in concrete is new properties such as Compressive strength, split tensile strength, pullout strength of M40 grade of concrete with the use of nano- silica 1.5%, 3%, 4.5%, 6%, 7.5% and 10% of constant rate of fly ash as a patrial replacement of cement were studied. It was observed from the experimental study that concrete composites with superior properties can be produced using combination of nano- Silica and Fly ash.
