Implication

This analysis shows potassium transport dynamics in concrete using laser-induced breakdown spectroscopy, suggesting improved prediction of re-alkalization depth.

Key Points

A time-dependent attenuation factor improves the prediction of re-alkalization depth based on potassium content.
Potassium transport does not follow an ideal diffusion process, indicated by the findings from laser-induced breakdown spectroscopy.
The study allows for the adaptation of Fick’s second law of diffusion to better suit the CRA process.
A potassium content of 2.3 wt% achieves complete re-alkalization to a depth of 16 mm, highlighting the effectiveness of hybrid alkali-activated binders.
