In the realm of cement concrete, super - fine active metakaolin stands out as a high - performance supplementary cementitious material. Its extremely fine particle size and high pozzolanic reactivity enable it to react with calcium hydroxide released during cement hydration. This reaction forms additional calcium silicate hydrate (C - S - H) gels, enhancing the concrete's density, strength, and durability. It also improves resistance to chemical attacks and reduces permeability, making it ideal for high - strength and long - lasting construction projects.

Washed kaolin is a cornerstone in the paper industry. After a thorough washing process to remove impurities, it offers excellent opacity, brightness, and printability. As a filler and coating pigment, it enhances the paper's surface smoothness, allowing for sharp and high - quality printing results.

Calcined kaolin is a key ingredient in ceramics. The calcination process alters its structure, increasing its whiteness and improving its thermal stability. It is used to adjust the firing temperature and shrinkage rate of ceramic bodies, ensuring consistent and high - quality ceramic products with fine textures and appealing finishes.
