摘要

A novel evaluation method of pozzolanic activity of metakaoline is studied.The pozzolanic activity can be evaluated by the measurement of the content of AlO4 tetrahedra.Base on this method,the influence of calcination time on pozzolanic activity of metakaoline is studied.The results indicate that the pozzolanic activity increases with the calcination time when calcination time is below 4 hours,and it decreases with the calcinations time increasing when the calcination time is 4-8 hours.
