On the project

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.
