MICRO SILICA

We are one of the potential suppliers of Micro Silica (Silica Fume) and it complies with ASTM C 1240 & EN 13263:2005. After it being procured from Silicon metal factories, it’s being recycled, Densified, and packed under completely automated and in closed environment.

PROPERTIES

  • Appearance : Fine Powder
  • Colour : Grey
  • Odour : Odourless
  • MPS : 25 Microns
  • SiO2 : 90% Min
  • Humidity : 2% Max

ADVANTAGES:

  • High compressive strength by 10 – 20
  • Reduces the rate of carbonation
  • Lower permeability
  • Lower free lime formation
  • Controls bleeding in fresh concrete
  • Lower Heat of Hydration, which prevents formation of cracks.

APPLICATIONS:

  • Construction Concrete, Mortar and PHC &UHPC Products
  • Refractories
  • Ceramics
  • Oil & Gas
  • Fertilizer
