Microfume 102 DM
Densified Silica Fume
JUMP TO
GENERAL DESCRIPTION
Microfume™ 102DM is a densified silica fume additive designed for use in oilwell cementing systems. Produced
from highly reactive amorphous silicon dioxide, this material provides extremely fine particles with a large surface
area that enhance cement performance under demanding well conditions. Microfume™ 102DM improves the
long-term strength and durability of cement sheaths by reducing permeability and refining the microstructure. The
densified form offers easier handling, blending, and bulk transport compared to undensified grades.
Densified, constant PH, amorphous light grey silicon oxide powder, obtained by filtering
the dusts extracted from the production of silicon metal in an electric arc furnace.
Other Names & Identifiers
- Supplementary Cementitious Material (SCM)
- Lightweight Cementing Additive
- Compressive Strength Enhancer
- Extender
- Permeability Reducer
- Microsilica
APPLICATIONS & BENEFITS
Recommendations
APPLICATIONS & BENEFITS- Strength enhancement: Increases compressive strength through pozzolanic reaction with calcium hydroxide, forming additional calcium silicate hydrates.
- Durability improvement: Lowers permeability to aggressive fluids, enhancing resistance to chemical attack (e.g., CO₂, H₂S).
- Lightweight or high-density cement systems: Compatible with a wide range of weighting agents and extenders.
- Safety: Product totally amorphous. Safety data sheet available on request.
