Micro Silica 92D is a densified silica fume with a silicon dioxide content of approximately 92%, supplied by SKF BIO TECH from Bardhaman, West Bengal. This pozzolanic admixture is engineered for high-performance concrete, delivering enhanced compressive strength, reduced permeability, and improved resistance to chemical attacks. The product meets ASTM C1240 and EN 13263 standards, making it suitable for critical infrastructure projects such as bridges, tunnels, and marine structures where durability is non-negotiable.
The material consists of amorphous silicon dioxide in ultra-fine particles, typically 0.1 to 0.3 microns in diameter, which increases surface area and reactivity in cementitious mixes. Standard industry grades for silica fume include 85D, 92D, and 94D, with 92D offering a balance of reactivity and cost efficiency for most commercial applications. SKF BIO TECH’s densified form ensures easier handling and reduced dusting compared to undensified silica fume, while maintaining the same pozzolanic benefits.
Buyers for this product are typically concrete producers, precast manufacturers, and infrastructure contractors requiring high-strength, low-permeability mixes. Common applications include shotcrete for tunnels, high-performance concrete for bridges, and refractory mixes for industrial furnaces. SKF BIO TECH offers flexible bulk supply options, with packaging and logistics tailored to project scale. Buyers should confirm lead times and incoterms directly with the supplier to align with construction schedules.

Before ordering Micro Silica 92D from SKF BIO TECH, verify the SiO2 content and compliance with ASTM C1240 and EN 13263 through a certificate of analysis. Confirm whether the material is densified or undensified, as this affects handling and storage requirements. Request documentation for any additional standards or certifications, such as ISO, that may be relevant to your project’s quality control protocols.
Discuss logistics with SKF BIO TECH to align lead times with your construction schedule, as silica fume is often shipped in bulk bags or super sacks. Clarify incoterms (e.g., FOB or CIF) and payment terms (e.g., L/C or T/T) upfront, as these can significantly impact landed costs. For large orders, confirm whether the supplier can provide consistent batch quality and whether partial shipments are feasible to manage inventory.
Conduct quality checks upon receipt by testing a sample for particle size distribution, moisture content, and pozzolanic activity. Inspect packaging for damage or contamination, as silica fume is highly susceptible to moisture absorption. For marine or chemical exposure applications, perform additional tests such as chloride penetration resistance to ensure the material meets your project’s durability requirements. Always retain samples from each batch for traceability.
