Silica Fume Concrete’s fine and amorphous particles react with cement alkalies which reduces their content in the concrete before hardening, thus protects the concrete against an alkali reaction. MasterLife SF 100 - Silica fume mineral admixture Description. MasterLife SF 100 is a dry, compacted, silica fume mineral admixture formulated to produce concrete with special performance qualities. Silica fume or microsilica is very fine non-crystalline silica produced in electric arc furnaces as a by-product of the production of elemental silicon or alloys containing silicon. Silica Fume Bisley and Company are major suppliers of Silica Fume (or Microsilica) throughout the Middle East, Asia, Australia and New Zealand.

The main application is concrete. The more information of silica fume can be found here: What is fumed 2020-04-22 Silica fume is a filter powder generated from the reduction of high purity quartz – ferrosilicon metals or silicon metals. Silica fume consists primarily of very fine smooth spherical silicon oxide particles with an extremely high surface area. silica fume properties. According to the SiO₂ content of silica fume powder, we divide the product into 85%–97% different specifications. The average particle size of the silica fume is 0.1-0.15 μm, which is a few percents of the average particle size of the cement.
