The A Z Guide Of SILICA FUME why we use it in concrete

The chemical formula of both silica fume and sand is SiO2. But both have different behavior in concrete. One is very reactive in concrete, while the other is inert. That may be due to, there type of solid structure. As the structure of sand is crystalline, so it cannot dissolve in concrete, but silica fume is a non-crystalline pozzolanic material which is very reactive. The reactivity of
