Metody pro zastavení hydratace cementu, vápna a sádry

Název projektu anglicky
Hydration stoppage techniques for cement, lime and gypsum
Anotace anglicky
For a study of setting and hardening kinetics of binders it is essential to stop ongoing processes by a proper method at a defined time. The project aims to study the effects of various hydration stoppage methods on microstructure and properties of cement, gypsum and lime pastes. Whereas the hydration stoppage of cements has been widely studied, there is a lack of knowledge in terms of arresting the setting and hardening processes of gypsum or lime, which differ significantly from those of cement. The most common hydration stoppage techniques, done by removing free water, for cements are mainly focused on relatively old materials, whereas the most important chemical processes take place within the first days of hydration when they still contain a significant amount of free water. Another important reason for removing free water is the fact that most of the characterization and analytical techniques require dry samples. The effects of various water removal methods on the microstructure preservation of studied pastes will be analysed with emphasis on early stages of hydration.
