Silica Fume Association 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 Association … Silica House (P) Ltd. - Importer and stockiest of synthetic rubbers, mold release agents, industrial synthetic rubbers, rubber mold release agents, industrial chemicals, automation of rubber plants system, rubber chemical products, industrial minerals, sourcing & verification services, silicone rubber, insulation material, polycarbonate and industrial products. 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, also known as microsilica, is an extremely fine noncrystalline polymorph of silica and is produced in electric arc furnaces (EAFs) as a by-product of silicon and ferrosilicon alloy production.While the first trials of silica fume as an Silica fume can also be pelletized, whereby the silica fume is mixed with water and some cement. The silica fume pellets can be ground with Portland cement clinker to form a blended cement. Irrespective of the delivery form of silica fume (i.e., as-produced, compacted, slurried, or pelletized), similar concrete properties and performance can be achieved ( Hooton, 1993; Zhang, Zhang, & Yan, 2016 ).

SF (also known as microsilica) is a by-product of the smelting process of silicon metal and ferrosilicon alloys used for steel and aluminum production (Silica Fume Association, 2005). In electric arc furnace, raw materials (quartz and coal) are smelted at high temperature. Silica fume, also known as microsilica, (CAS number 69012-64-2, EINECS number 273-761-1) is an amorphous (non-crystalline) polymorph of silicon dioxide, silica.It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 nm. Silica fume, also known as microsilica and nanosilica, is a highly reactive pozzolanic filler, which is used to achieve high strength and dense concrete.
