Volcanic Ash from Tajogaite Volcano (La Palma Island, Spain) as Pozzolanic Material in Lime and Cement Blends

Buildings
The eruption of the Tajogaite volcano (Cumbre Vieja) on La Palma Island (Spain) generated a significant amount of volcanic ash (VA). This study evaluates the valorisation of VA, considered a “natural waste,” as a partial substitute for Portland cement or
