Abstract: Nanotechnology is an advanced technology that has received a lot of attention for its ability to make use of the unique properties of nano-sized materials. The grain size of the nano particles will be in the order of 10-9 m (1-100nm). Due to the very small particle size of 10-9 m and extremely large specific surface area, nano particles have same remarkable properties. The use of nano materials for making concrete is of recent origin. Application of nano materials into the production of concrete can lead to significant improvements in the strength and life of concrete. Recent year’s enormous work is executed by incorporating urban wastes in building materials. Disposal of used tyre is a major problem faced by the present world. The growing problem of waste tyre disposal can be alleviated if new recycling routes can be found for the surplus tyres. The incorporation of waste materials in concrete benefits the environment and modifies the properties of concrete. An attempt has been initiated to study the properties of concrete by incorporating the potential utilization of crumb tires as a partial replacement of fine aggregate and nano silica fume(NSF)as the partial replacement of ordinary Portland cement of 53 grade. M sand free of debris and good gravel was used. Nano silica fume are produced by grinding the commercially available micro silica in the ball grinding mill. Crumb rubber is produced by shredding process. Mix design for M30 grade of concrete was done as per IS10262-2009. Cement is replaced with 10%, 20%, 30% 40% and 50% of nano silica fume and fine aggregate was replaced with 20%, 40%, 60%, 80% and 100% of crumb rubber. Test on compression, tension and bending was studied. It was found that concrete with crumb rubber has lowered workability. The optimum replacement of fine aggregate with crumb rubber was found to be 20% without nano silica fume and 40% with nano silica fume.
