By thermodynamic calculations established the mechanism of hydration of lime - the main component of the gas-silicate materials. As a result, it became possible to conduct targeted searches of additives that slow the lime slacking process. The hypothesis of the transformation of β-quarts at the temperature 150-200 °С into β-cristobalite and β-tridymite was justified. This causes the Hedwall effect and an accelerated synthesis of the calcium hydrosilicates and calcium hydroaluminates during the autoclave treatment of gas-silicate materials.
