Il 'vetro vulcanico vescicolato' nell'industria italiana del cemento del primo Novecento

The transition from mixed construction (load-bearing masonry and reinforced concrete frame) to the introduction of light infill diaphragms caracterized the passage to modern architecture. Especially in Italy, this finds evidence in the ex- perimentation of peculiar materials and technological solutions in the early XX century. The pumice stone cement is among the most important and widespread solution: exploiting the volcanic deposits of the Aeolian Islands (in particular the island of Lipari) this material was applied for the construction of horizontal and vertical building systems, with thermal and acoustic insulation properties and experiments of fireproof frames.
