APPLICATION OF NANOTECHNOLOGY IN IMPROVING THE PERFORMANCE OF CEMENTITIOUS COMPOSITES

Abstract

In recent years, the world of science has started to produce new materials and 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 matrix and concrete have been summarized and evaluated. The influence of nano particles such as nano silica fumes and nano fly ash in cement matrix and concrete was studied with reference to normal size particle cement matrix and normal size concrete. The morphology of nano particles was studied using Transmission Scanning Election Microscopy (TEM) and electron microscope. Also, X-ray diffraction (XRD) of all the mineral additions was studied. The results indicated that the addition of nano particles improves the properties of cement matrix and concrete.
