SikaFume®-300

SILICA FUME IN POWDERFORM AS AN INORGANIC CONCRETE ADDITIVE
 

SikaFume®-300 is a fine, pozzolana additive for the production of high-strength, dense and durable concrete according to DIN 1045.

  • Increases the compressive-strength
  • proving the binding between cement paste matrix and aggregate grains
  • Reduction of porosity through reaction with cement constituents
  • Improved stability and rheology
  • Higher abrasion resistance
  • Reduces rebound in shotcrete
  • Reduction of efflorescence
  • Increases the resistance to freezing/thawing and de-icing salts
  • Improvement of the chemical resistance

Application

Application Information

Dispensing

SikaFume®-300 must be simultaneously added with the cement. To reduce the increased water demand, utilise Sika ViscoCrete. The required mixing time after the addition is dependent on the mixer and must be sufficiently dimensioned.
Consumption

Recommended dosage

max. 11 % of cement weight
Initial testing according to DIN EN 206-1/DIN 1045-2 is required.
