Pyroclastic volcanic ash as a potential precursor of alkali-activated binders - A case study from Tajogaite (La Palma, Canary Islands) volcano eruption

The volcanic eruption of Tajogaite in La Palma (Canary Islands, Spain) produced approximately 200 Mm3 of fine lapilli and ash. Using this volcanic ash (VA) to produce alkali-activated binders (AABs) fosters a sustainable approach to binder manufacturing, aligning with the principles of a circular ec...
