Silica Fume in Mortars & Grouts

Home / Application / Silica Fume in Mortars & Grouts

Silica fume is used in a variety of cementitious repair products.  Mortars or grouts modified with silica fume can be tailored to perform in many different applications—overhead and vertical mortars benefit from silica fume’s ability to increase surface adhesion.  Silica fume dramatically improves cohesiveness making it ideal for use in underwater grouts, decreases permeability in grouts used for post-tensioning applications and increases the resistance to aggressive chemicals.

  • -Non-bleeding and non-segregating
  • -Low permeability
  • -Lightweight
  • -Increased resistance to attack from chlorides, acids, nitrates and sulfate
