The application of Nano-Technology in cement mortar or concrete has added new dimension to the efforts toimprove its different properties. Nano-particles, because of their very small particles size can affect the properties of acement mortar or concrete by changing its micro structures. This study concerns with the use of fumed silica as a nanoparticles and metakaolin to improve the compressive strength of the nano-concrete. An experimental investigation hasbeen carried out to replace the cement with fumed silica of 2%,5%,6%,7%,8%,9% &10% and metakaolin of 10%,15% &20%. The tests conducted on it shows a considerable increase in the compressive strength. The strength increase wasobserved with a certain amount of Fumed silica & metakaolin. The FSEM micrograph shows that the micro structures ofhardened nano-concrete is improved on addition of fumed silica. A sample of industrial kaolin and a representativesample is taken from Swat Khyber Pukhtton Khwa Pakistan mine reservoir and tests like thermo gravimetric analysis andX-ray diffraction are performed, to find out either it is kaolin or some other mineral.
