Effect of atmospheric exposure on alkali activated binders and mortars from Mt. Etna volcanic precursors

Roberta Occhipinti et al.

Summary: Research has shown that alkali activated binders and mortars made from volcanic pyroclastic residues from Mt. Etna are barely affected by atmospheric exposure after being outdoors for six months. The composition, mechanical properties, dynamic vapour sorption, and visual aspect of the materials remained relatively unchanged before and after exposure, demonstrating their durability in outdoor conditions.

Potentiality of the Use of Pyroclastic Volcanic Residues in the Production of Alkali Activated Material

Germana Barone et al.

Summary: The study investigated the potential use of volcanic residues for the production of alkali activated material, particularly for the restoration of Baroque Sicilian architecture. By activating volcanic pyroclastic deposits considered waste materials and adding different amounts of metakaolin in the formulations, small quantities of zeolites were formed as a result of the alkali activation process. The mechanical-physical results showed a strong dependence of mechanical strength on the metakaolin amount, indicating the potential of these pyroclastic wastes for valorization in the restoration field.
