Silica fume

Silica fume delivers increased toughness and resistance to abrasion and corrosion, improving sustainability and life-cycle cost efficiency. 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. Silica fume is an ultra-fine powder consisting of nearly spherical particles around 100 times smaller than a grain of cement.
