Abstract: Nano technology is the incorporation of nano sized particles. Particle in nano size can enhance the structural property in concrete. Past study reveals that nano particles increase the strength and durability of concrete. Permeability tests in concrete showed that the behaviour of concrete for durability depends mainly on its degree of absorption and porosity of concrete. Materials incorporated at nano size results in improving property of the concrete composites. Experimental investigation has been done to understand the influence of nano materials on the sorptivity and water absorption of concrete. M20 grade, M30 grade, M40 grade and M50 grade of concrete has been used. Cement was replaced with 10%, 20%, 30%, 40% and 50% of nano sized cement, fly ash and silica fume. Materials were converted to nano size by grinding in ball milling machine and its particle size was determined by scanning electron microscope. It was found that cement replaced with 50% of nano cement showed less moisture ingression and less water absorption.
