With the growing infrastructure development all around the world demand of Portland cement are increases day by day. The huge production of cement is associated with releases of CO2 causing global warming issues. Therefore several efforts are in progress to reduce the use of Portland cement in concrete. These include the utilization of supplementary cementing materials such as fly ash, silica fume, granulated blast furnace slag,,rice-husk ash and metakaolin etc. The concept of sustainability of structures is touching new heights and many green building materials are tried and tested as partial or complete replacement for the cement. In this respect, the geo-polymer technology shows considerable prospect for application in concrete industry as an alternative binder to the Portland cement. Development of geo-polymer concrete using class F flyash brings many advantages like; enhancing workability, durability, better strength as well as lowering the price. Nowadays, Nano Technology is also gaining prominence in the field of construction industries. In this study an attempt is made to find the effect for addition of Nano silica in geo-polymer concrete .The geo-ploymer concrete specimens were prepared using different percentage of nano silica. After finalizing the mixed design, the compressive strength was determined. The experimental study also carried out for durability aspects under different aggressive environment. The results obtained shows that geo-polymer concrete with nano silica addition exhibit good strength and excellent durability performance in aggressive environment. The beneficial effects of nano-silica in improving the workability, microstructure and strength qualities have also been established experimentally.
