• Dramatically decrease permeability, for better control of gas leakage

CONCRETE - key component for making high performance concrete, typically either high-strength or low

CEMENT- used to make blended silica fume cement and alternative method to making high-performance

CEMENTITIOUS REPAIlR 一 used with other raw materials in concrete, mortar or grout“pre-packaged” bagged

ELASTOMERS/POLYMERS - used as a filler in rubber or plastic.

FERTILIZER 一 used in the defluorination process during the production of dicalcium phosphate (animal feed).

OIL & GAS WELL -used in down hole grouting operations, improves flow (lightweight) and decreases permeability.

FIBER CEMENT - used to improve strength and permeability of corrugated roofing panels.

REFRACTORY - used to improve flow characteristics and produces a denser matrix.

SHOTCRETE - is sprayed concrete, silica fume reduces rebound & increases bonding strength, productivity and savings in

Wallboard - used in commercial gypsum and concrete walboard products for increased performance.

• Very low permeability to chloride and water intrusion

• Extremely high electrical resistivity (20 to 100 times greater than ordinary concrete)

• Increased abrasion resistance on decks, floors, overlays and marine structures

• Superior resistance to chemical attack from chlorides, acids, nitrates and sulfates

• Very high-strength concrete

 • Compressive strengths up to 20,000 psi (140Mpa)

• High modulus of elasticity exceeding 6 million psi (40,000 Mpa)

• High flexural strengths (2,000 psi @ 28 days) for airport pavements

• High early strengths for fast-track construction projects and precast applications

• Improves particle packing, strength at high temperatures

• Reduces water while maintaining the same flow characteristics

• Promotes low temperature sintering & the formation of mullite

• Reduces permeability to avoid gas, slag and metal penetration

• Increases bonding strength

• Decreases permeability to water intrusion

• Improves yield

• Increases compressive strength

• Improved flow, for easier, more effective application

• Increased durability and compressive strength

• Lightweight
