摘要：

Many estimation methods for the reactivity of the metakaolin were investigated. The results are as follows: (1) XRD analysis could not be solely used for estimating the reactivity of metakaolin; (2) the method of absorbing alkali can evaluate qualitatively, but the absorbing amount evolution do not accord with that of the compressive strength up to 3d; (3) the method of absorbing calcium could not be suitable to the valuing purpose in this system; (4) the method of "pressing to test strength" is probably a preferable one to appraise the reactivity of metakaolin; (5) the best estimation method is to test the strength of geopolymers which were made of metakaolin and cured till certain age. The other method results must be accord with this. But this method is excessively time-consuming, and is not applicable to production.
