The world of science has started to produce new materials and also to study their properties using nanotechnology. The use of nanotechnology has become wide spread in all branches of science and technology. In this study, the use of nano powders in cement mortar and concrete has been used and their performance has been evaluated. The influence of nano particles such as nano silica fume, nano flyash and fine grinded cement in cement mortar and concrete has been studied with reference to normal size particles of cement mortar and concrete. The morphology of nano particles was studied using Transmission Electron Microscopy (TEM) and Scanning Electron Microscope. Also, X-ray diffraction of all the mineral admixtures was studied. The results indicated that the addition of nano particles improves the properties of cement mortar and concrete
