Microsilica – fine-grained dust derived from production of ferrosilicon and silicon. Silica fume consists of tiny, perfectly spherical particles. Thanks to these properties it fills space between cement particles and aggregates which has a positive effect on concrete: porosity, waterproof, swelling reduction and increase of durability.

Microsilica meets the requirements of European standard EN 13263.  

Silica fume is available in two types:

  • non-concentrated – with bulk density up to 350 kg/m3
  • concentrated – with bulk density between 450-700 kg/m3

General information:

Appearance – very powdery amorphous dust – it can create bigger particles
Color - grey
SiO2 - min. 85 %
