Процесс образования таумазита изучен с помощью спектроскопии комбинационного рассеяния света и термодинамического анализа для выявления изменений таумазита в растворе соли аммония при температуре окружающей среды 25 °C. Показаны ускорение реакции в присутствии ионов NH4+ при температуре окружающей среды и усиление этой тенденции в присутствии анионов SO42−.  Это усиление больше, чем при низкой температуре. Изменение свободной энергии Гиббса образования таумазита в присутствии и в отсутствие ионов NH4+ изучено с использованием термодинамических методов. Объяснен механизм ускорения образования таумазита в присутствии ионов NH4+.

Cement-based materials sometimes encounter sulfate attack and ammonium salt environments during service, which can severely affect the long-term durability of these materials. In cement-based materials, the formation of thaumasite usually requires five conditions: sulfate, silicate, carbonate, and sufficient water and low temperature (15C). However, under other conditions, thaumasite can also form. To study the changing trend of thaumasite in an ammonium salt solution at ambient temperature (25C), the formation process of thaumasite was studied by laser Raman spectroscopy and thermodynamic analysis. The reaction was accelerated in the presence of NH4+ ions at ambient temperature, and the presence of SO42− anions enhanced this trend; this enhancement was even greater than that at low temperature. The change in the Gibbs free energy of formation of thaumasite in the presence versus absence of NH4+ ions was studied using thermodynamic methods, and the acceleration mechanism of the formation of thaumasite in the presence of NH4+ ions was explained.
