The effect of kaolin firing regimes on its properties are considered. Heat-treated specimens are studied by x-ray phase analysis, infrared spectroscopy, and gel pycnometry. It is established that the most active metakaolin (additive activity 360.5 mg/g) forms at 650°C and isothermal exposure for 30 min.
