Research of method of quick testing metakaolin activity

The common method of testing metakaolin activity is submersion by NaOH liquor at room temperature.A new method of submersion by saturated Ca(OH)2 liquor is introduced by which the consumption of Ca(OH)2 and NaOH2 is measured to assess the activity of metakaolin.The practice shows this new method can quickly test the activity of metakaolin.
