高活性偏高岭土简介：

偏高岭土是以高岭土矿石为原料，经过选矿-破碎—磨矿—煅烧等工序制作而成，是一种具有高火山灰活性的物质，主要成分是无定型的Al2O3和SiO2。主要应用领域在混凝土行业，也叫做高性能混凝土矿物外加剂。

Introduction of high active metakaolin:

metakaolin is made from kaolin ore as raw material, after processing, crushing, grinding and calcination. It is a substance with high pozzolanic activity. Its main components are amorphous Al2O3 and SiO2. The main application field is in the concrete industry, also called the high performance concrete mineral admixture.

Use of metakaolin:

All the products that use Portland cement can be used in the metakaolin, and whether they can be applied really depends on the ratio of performance and price. According to the preliminary research and application practice, the products of the metakaolin can be used in the following products.

1, high performance concrete mineral admixture, such as prestressed concrete, lightweight concrete, high strength concrete, repair concrete and so on.

2, special mortar admixtures, such as insulation mortar, waterproof mortar, adhesive mortar and plaster mortar, waterproof wall putty, single two-component polymer cement waterproof mortar, repairing mortar, self leveling mortar etc..

3, polymer cement waterproof slurry, double component polymer modified ceramic wear-resistant floor coating and so on.

4, raw materials for geopolymer production, such as geopolymer coatings, geopolymer grouting materials, geopolymer imitated tile materials, geopolymer cement, geopolymer, artificial marble and so on.

5. Refractory material additives.

6. The filler of polyurethane waterproof coating.
