TechnoCem® MicroSilica

Ready to use powdered concrete admixture

TechnoCem® MicroSilica is a ready to use powdered (silica fume) concrete admixture composed of silicon dioxide (SiO2), collected from silicon metal and ferrosilicon. TechnoCem® MicroSilica reacts chemically with the calcium hydroxide in the cement paste which yields a calcium silicate hydrate gel that significantly enhances strength and durability. TechnoCem® MicroSilica fills the voids between cement particles creating a very dense, less permeable concrete. TechnoCem® MicroSilica contains no added chlorides or chemicals known to promote the corrosion of steel.
