Con Fume
Premium densified silica fume pozzolanic admixture that reacts chemically with calcium hydroxide to produce ultra high strength, low permeability concrete.
Key Features and Benefits
- Ultra low permeability:Drastically reduces chloride ion penetration and moisture transport
- High compressive strength:Enhances early and 28 day compressive strengths beyond 80 N/mm²
- Chemical resistance:Shields concrete from sulfate attack, de icing chemicals, and acidic soils
- Bleeding reduction:Eliminates bleed water and honeycombing in pumpable mixes
Recommended Areas of Application
Ideal structural locations and substrates
High performance and ultra high strength concrete
Marine bridges, jetties, and coastal structures
Concrete exposed to severe chemical effluent
Shotcrete tunnel linings and rock stabilization
Heavy traffic bridge decks and wearing surfaces
