microsilica gel

Description

microsilica gel

Normal microsilica gel is a modified and developed additive based on polycarboxylate ether, consisting of microsilica powder, polycarboxylate superplasticizer, water repellent and polypropylene fibers. This additive is used to make a variety of powerful, impenetrable and durable concrete.

Features:

• Prevention of water dissipation and separation of concrete
• Prevent cracks caused by thermal stress of concrete
• Reduce permeability against water, chlorine ion and sulfate influx

Applications:

• Construction of concrete docks, bridges, bridge decks, reservoirs and dams
• Concrete pouring in areas that have been attacked by chemicals and corrosive
• Suitable for construction of concrete exposed to explosion

Microsilica Gel – Advanced Additive for High-Performance, Waterproof Concrete

Microsilica Gel is a cutting-edge, multi-component concrete additive engineered to significantly improve the strength, impermeability, and durability of concrete in demanding environments. This innovative product is based on modified polycarboxylate ether technology and incorporates microsilica powder (also known as silica fume), a high-range water reducer (polycarboxylate superplasticizer), a water repelling agent, and polypropylene reinforcement fibers. Together, these elements create a synergistic effect that transforms conventional concrete into a high-performance material suitable for modern infrastructure and heavy-duty applications.

Unlike traditional concrete additives, Microsilica Gel acts simultaneously as a densifier, strength enhancer, permeability reducer, and anti-cracking agent. Its finely graded microsilica particles fill the voids within the cement matrix, producing a denser microstructure with dramatically reduced capillary porosity. The superplasticizer component enhances workability without increasing water content, while the integrated fibers and hydrophobic agents contribute to crack control and water resistance.

Key Features and Benefits

• Prevents Segregation and Bleeding: Microsilica Gel stabilizes the cement paste, reducing water migration and aggregate segregation, leading to a uniform and cohesive concrete mix.
• Thermal Crack Resistance: Reduces the formation of thermal shrinkage cracks by lowering the internal temperature gradient during concrete hydration, especially in mass pours such as dams and reservoirs.
• Exceptional Waterproofing: By significantly reducing water absorption and permeability, it acts as a highly effective barrier against water ingress, even under high hydrostatic pressure.
• Superior Resistance to Chemical Attack: Provides long-term durability in environments containing aggressive ions like chlorides and sulfates, making it ideal for marine and coastal applications.
• High Early and Final Strengths: Increases both compressive and tensile strength due to improved hydration kinetics and internal particle packing.
• Fiber Reinforced for Crack Bridging: The inclusion of polypropylene fibers improves ductility and prevents microcrack propagation under stress or movement.
• Enhanced Concrete Durability: Protects internal reinforcements from corrosion by minimizing pore connectivity and blocking chloride ion penetration.

Applications of Microsilica Gel

Microsilica Gel is highly versatile and is used in a wide range of civil, structural, and industrial projects where strength, longevity, and water resistance are mission-critical. Common application areas include:

• Marine and Port Structures: Ideal for concrete docks, wharves, piers, and offshore platforms exposed to continuous water immersion and salt spray.
• Bridge Decks and Highway Infrastructure: Reduces chloride-induced corrosion and extends service life in deicing salt environments.
• Water Retaining Structures: Used in water tanks, canals, swimming pools, reservoirs, and large dams to prevent seepage and leakage.
• Chemical Plants and Industrial Flooring: Protects against aggressive chemicals, acids, and solvents in processing facilities and heavy-use industrial surfaces.
• Military and Explosion-Resistant Structures: Provides additional structural integrity and crack resistance in facilities subjected to impact, vibration, or explosive loads.
• Tunneling and Underground Works: Suitable for use in metro tunnels, utility galleries, and basements where waterproofing and durability are essential.
• Shotcrete and Sprayed Concrete: Enhances adhesion, reduces rebound, and improves final strength in sprayed applications such as slope stabilization and tunnel linings.
