The product is a high active meta kaolin. It is a completely inorganic material, which can improve the quality and speed of the product hydration reaction, and the direction stability of the product, that is, it can reduce dry shrinkage and the cracking or deformation caused. It also can improve product density, especially product surface hardness and permeability resistance. It has better performance to use with cement and can replace a large part of the white additive material.
Main application:
Cement, concrete, inorganic self-leveling floor, inorganic artificial stone, building putty, etc.
