Alkali activated materials are regarded as a substitution building material of Portland Cement (PC) with high chloride resistance and low CO2 footprint. This review study provides a multi-scale perspective to understand material-product-microstructure-property relationships in terms of chloride binding behavior of AAMs. Physical and chemical chloride stability of different reaction products is summarized from nanostructure, microstructure to macro properties. The analysis of cited studies are determined to give an overview of recent progress in chloride transport in AAMs influenced by different reaction products. Results show that higher Ca/Si, Al/Si molar and alkali content increase amorphous phases formation, leading to a denser microstructure and lower chloride penetration in AAMs. Higher MgO and Al2O3 incorporation results in more formation of hydrotalcite. The enhanced physical and chemical absorption of chloride by hydrotalcite leads to higher resistance of chloride penetration in AAMs. The investigation of increasing chloride resistance can potentially focus on the increase of gels and hydrotalcite formation.
