Microsilica, also known as silica fume, is primarily used in the concrete and construction industry to create high-strength, durable, and low-permeability concrete for applications such as skyscrapers, bridges, and tunnels. It improves concrete's compressive strength, abrasion resistance, and resistance to corrosion from chlorides and sulfates. Beyond concrete, microsilica is used in shotcrete, cementitious repair products, and as a filler in polymers, rubbers, and some ceramics.
High-Strength Concrete: Produces concrete with significantly improved compressive and flexural strength used in skyscraper foundations, columns, and beams.
High-Performance Concrete: Ideal for harsh environments such as marine structures and industrial floors with superior density and chemical resistance.
Abrasion & Corrosion Resistance: Extends lifespan of hydraulic structures, bridge decks, and spillways by improving resistance to wear and chloride intrusion.
Reduced Permeability: Generates dense, low-porosity concrete perfect for waterproof applications like tunnels, subways, and dams.
Shotcrete: Enhances bonding strength and reduces rebound in shotcrete applications, boosting productivity in tunnel and foundation work.
Repair Mortars: Restores structural integrity and prolongs the life of repaired concrete infrastructure
