Abstract
The technique is presented for the determination of chemically bound water in metakaolin (with the mass fraction of water being within 0.5 and 5 %) by IR spectrometry at 900°C using the ELTRA (Germany) CW-800M infrared spectrometer. A single sample can be tested within 5 – 6 min, allowing for quality control of incoming metakaolin samples keeping defective samples out of production. The possibility of water determination at 600°C was shown, in which case analysis time increases to 20 – 22 min. The developed technique for the determination of chemically bound water in metakaolin provides results with sufficient accuracy and precision.
