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,是一种具有极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.
