Among all the materials used in construction, concrete occupies nearly 70% of the materials by volume and shows significant impact. The advent of nanotechnology helped in producing more strong and durable material than conventional materials. Nanotechnology in making concrete refers to the production and addition of nanosized particles in to concrete at suitable proportions by appropriate methods. The basic purpose of using nanosized materials in concrete is to improve compressive and flexural strengths at early age, it is possible due to the high surface – to volume ratio.
