SFA definition: Silica rök Association - Silica Fume Association

It is an ultrafine powder collected as a by-product during the production of the silicon and ferrosilicon alloys. 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. Silica Fume Introduction Silica Fume SupplementaryCementitious Materia.

What is the definition of silica fume?Its alias?And how is it produced? Physical Forms of Amorphous Silica Silica Fume Undensified Amorphous Silica. The term ‘undensified’ describes condensed silica fume sourced directly from a silicon or ferro silica furnace; the bulk density at source can be as low as 150kg/m³ and has the consistency of a thick smoke. Silica Fume may contain trace amounts (<0.05%) of crystalline silica (quartz), which has been shown to cause silicosis, and has been identified by IARC and NTP as a possible human carcinogen.
