TechnoCem MicroSilica

Powdered, Densified Silica-Fume 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.
