The technique is presented for the chemically bound water determination in metakaolin (the mass fraction of water being within 0,5 and 5 %) using the ELTRA (Germany) CW-800M infrared spectrometer analyzer at 900 °C. The analysis of one sample lasts within 5 and 6 minutes, this allows to control for the metakaolin the incoming samples and not to pass the defective product into operation. It was shown that the analysis for the water can be carried out at 600°C, given that the analysis lasts 20‒22 minutes. The developed technique of the metakoalin test for chemically bound water has the acceptable accuracy and convergence.
