Overview

Observational analysis achieved realkalization depths of 30 mm in reinforced concrete, highlighting the role of binder chemistry.

Key Points

  • Realkalization depths of up to 30 mm were achieved using hybrid alkaline-activated binders under specific conditions.
  • The study emphasizes the role of binder chemistry and initial suction in the effectiveness of the realkalization process.
  • Alternative pH indicators provided a more precise analysis of the spatial and temporal evolution during realkalization.
  • This research advances the understanding of interactions between binder components and the realkalization effectiveness.
