Hybrid fly ash based alkali activated cements

Alkaline activation is one of the most perspective ways for creating very high volumes fly ash cements. 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
