TOTAL REPLACEMENT OF CEMENT USING SILICA FUME AND FLY ASH

Cement manufacturing industries emits 5% of global carbon di-oxide which in turns leads to the main causes for the global warming. To reduce the effects we can replace the cement with industrial by- product like silica fume, fly-ash and so on. In this paper we have replaced cement totally with silica fume and fly-ash. By replacing with the proportions of fly-ash (80%) and Silica fume (20%), it showed a greater strength result.
