Usage of Metakaolin
1. High-reactivity Pozzolanic Admixture for Concrete & Mortar
It reacts with calcium hydroxide in cement system to form stable hydration products, greatly improve compressive strength, impermeability and crack resistance of high-performance concrete, grout and repair mortar.
2.Raw Material for Geopolymer Binder
Used to produce geopolymer cement, a low-carbon eco-friendly inorganic binder with excellent acid resistance and high temperature resistance.
3.Functional Filler for Coatings & Adhesives
Added into water-based coatings, anti-corrosion paints and adhesives to boost abrasion resistance, compactness and storage stability of finished products.
4.Sintering Additive for Ceramics & Refractories
Optimizes sintering behavior, improves product whiteness and thermal stability, widely used in sanitary ceramics, ceramic tiles and low-temperature refractory materials.
