In recent years, Condensed Silica Fume (CSF) have been widely used for the construction of concrete structures in countries such as UK, USA, Japan and Europe for economical and ecological reasons, since CSF is the by-product of induction ore furnaces in silicon metal and ferrosilica alloy industries in these countries. Therefore, most research work on the use of CSF as partial replacement of Ordinary Portland Cement (OPC) has been carried out. The important characteristics of concrete are its compressive strength and durability. Durability of concrete is the most important between these two factors, which indicates the long term strength of concrete. Durability is inversely proportional to permeability. In this investigation, the influence of partial replacement of OPC by CSF in high strength concrete and the factors affecting durability are studied with respect to its resistance to chloride ingress based on diffusion of chloride ion.
