The main phases of structure in such “hybrid” systems are represented by mixes N-A-S-H and N-C-A-S-H new formations. The paper is showing differences in structure formation and properties of low-Ca and high-Ca-containing fly ash alkali activated cements. Appropriate pplications are shown.enfly ashalkali activated materialsArticle
