Micro Silica 85D from SKF BIO TECH is an undensified silica fume with a minimum SiO2 purity of 85%, supplied under the SKF Grade brand. This ultra-fine amorphous silica material is engineered for high-performance pozzolanic applications, with particle sizes optimized for uniform dispersion in concrete mixes. It is sourced from Bardhaman, West Bengal, and packaged in big bags or 25 kg sacks for bulk export.
The material enhances concrete durability, compressive strength, and chemical resistance, making it a critical additive for infrastructure, marine, and precast construction projects. Its pozzolanic properties stem from the high SiO2 content, which reacts with calcium hydroxide to form additional calcium silicate hydrate, improving the matrix density. Typical applications include high-strength concrete, shotcrete, and refractory mixes where resistance to abrasion and chemical attack is required.
SKF BIO TECH’s Micro Silica 85D is traded globally, with India serving as a primary production hub. Buyers in construction and engineering sectors source this material for projects demanding superior performance in harsh environments. The supplier’s location in Bardhaman provides access to regional logistics networks, facilitating efficient export to international markets.
