Strength improvement by partial replacement of portland cement binder (OPC) with condensed silica fume (CSF) has been extensively reported 1,, this can be at the expense of increased water demand .Use of alternative ultrafine materials based on byproducts such as ultrafine ground granulated blast furnace slag (UFS) and ultrafine flyash (UFA) has been less widely reported.
Groundgranulated blastfurnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a byproduct of iron and steelmaking) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.
