The Silica Fume Association (SFA) was formed in 1998 to assist the producers of silica fume in promoting its usage in concrete. Silica fume, a by-product of silicon and ferro-silicon metal production, is a highly-reactive pozzolan and a key ingredient in high-performance concrete, dramatically increasing the service-life of structures.

Keywords are: silica fume, silica, condensed silica fume, microsilica, pozzolan, pozzolanic, concrete, shotcrete, high strength concrete, high performance concrete, concrete admixture, blended silica fume cement, reactive powder concrete, oil well grout, and durable concrete.
