O projektu

The type of alkali and its content play a significant role corresponding to the potential of alkali-silicate reaction (ASR) in cementitious composites. Various alkalis contribute to the ASR differently, especially due to the diversity in ionic radius and solvation shell cover. Hence these parameters also influence their mobility. The methods for the in-situ monitoring of diffusion rate of Na+ and K+ ions relative to parameters like alkali type/concentration, matrix permeability will be evaluated same as the processes of the reverse leaching.

Popis anglicky
The aim of the project is to create a competition for student research grants and its pilot verification. The creation of a new competition will contribute to the development of cross-sectional skills of doctoral students, and thus acquire competencies for work in science and research in the future and increase their success in submitting scientific projects to national and international competitions.
