SiO₂
Silica Flour — HTHP Cement Stabilizer
Fine ground silica used to stabilize Portland cement slurries at temperatures where strength retrogression occurs.
Application
Portland cement slurries typically above ~110°C BHCT, per slurry design and operator procedure.
Technical characteristics (quality certificate)
Typical values as stated on a mill quality certificate (passport) for a standard commercial grade. Actual lot values are confirmed in the COA / TDS for the selected manufacturer.
