Abstract: Nanotechnology has received a lot of attention for its ability to make use of the unique properties of nano-sized materials. Nanotechnology is a very active research field and has applications in a number of areas. Currently this technology is being used for the creation of new materials, devices and systems at molecular, nano and micro-level. Recently, nanotechnology has attracted considerable scientific interest in civil engineering field due to the new potential uses of particles in nano-scale. Concrete with nano materials has some remarkable properties. In this experimental work, an attempt has been made to determine the influence of nano-materials on the durability of concrete. Chloride permeability of concrete in which cement was replaced partially with nano-cement, nano-flyash, nano-silica, nano- silica fume were found. Different grades of concrete viz., M20, M30, M40 and M50 were cast with nano materials. For each grade of concrete, 0%, 10%, 20%, 30%, 40% and 50% of cement was replaced with nano materials. Nanomaterials were obtained by grinding the micro sized materials in a ball grinding machine and the particle size was determined by using Scanning Electron microscope. The chloride permeability of concrete with nano-cement, nano-fly ash, nano-silica and nano- silica fume were determined using a Rapid Chloride Permeability Test (RCPT) apparatus and the results are compared with that of the Normal Cement Concrete (NCC).
