摘要
高岭土在经700℃～800℃热处理得到新型高活性混凝土偏高岭土（Metakaolin）矿物掺和料，所配制的混凝土具有良好的力学性能和耐久性能。本文详细介绍了MK掺和料的火山灰特征及在混凝土中的应用机理，以及国内外偏高岭土的研究现状和应用前景。
Baking kaolin by heat treating of 700℃ - 800℃ ,a new mineral admixture metakaolin powder with high pozzolanic reactivity is attained. The concrete compounded by the meakaolin has good mechanical properties and durability. In this paper, the use of metakaolin possessing high pozzolanic reactivity in concrete was studied. The mechanism of metakaolin incorporated in concrete and the present and future study for metakaolin were introduced.
