Silica fume for oil well grout
Microsilica is used in a variety of cementitious repair products. Mortars or grouts modified with Microsilica can be tailored to perform in many different applications—overhead and vertical mortars benefit from Microsilica’s ability to increase surface adhesion. Microsilica 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.
