Micro Silica


Microsilica, also known as silica fume or condensed silica fume, is a mineral admixture composed of very fine solid glassy spheres of silicon dioxide. It is usually found as a by-product in the industrial manufacture of ferrosilicon and metallic silicon in high-temperature electric arc furnaces.

MicroSilica is a super pozzolan or a finely powdered material used for providing strength and durability tot he concrete mix. This material in compliance with the ASTM C618 standards and have many advantages when added to cement and concrete. The silica content in micro silica is very high i.e., over 90%. some of the specifications of this material are mentioned below:

  • Appearance :Very fine powder
  • Colour : Grey
