Advances on chlorine fixation properties of alkali activated cementitious materials

Inhalt:
With the continuous expansion of the number and scale of sea related projects, the destructive effect of chloride ions on structures in the ocean has attracted more and more attention. Based on the existing research results, this paper expounds the chlorine fixation mechanism of alkali activated cementitious materials from three aspects: hydration products, chlorine fixation methods and influencing factors. This paper summarizes the research on the chlorine fixation performance of alkali activated cementitious materials at home and abroad, and puts forward the direction worthy of research in the future.
