英文摘要：

The study on the pozzolanic activity and the effect on the workability,mechanical performance and durability of metakaolin was reviewed.Literatures showed that metakaolin has the characteristics of efficiently enhancing the strength of concrete,improving the impermeability and anti-corrosion property of concrete,and suppressing alkali-aggregate reaction expansion in concrete.It is a kind of promising activity admixture.
