Toward Zero-Carbon Concrete: Alkali Activation of Ladle Furnace Slag Using Cement Kiln Dust

Buildings
This study investigates the potential of producing zero-clinker, alkali-activated binders and concrete entirely from industrial by-products—ladle furnace slag (LFS), coal ash (CA), and cement kiln dust (CKD).

Hybrid fly ash based alkali activated cements [PDF]

, 2013
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.
