The pumice aggregates of Lipari Island (Aeolian Isles-Italy)

In the Island of Lipari (Aeolian Archipelago) there is a large pumice deposit. The pumice is exploited in an open-cast mine through mechanical means and taken to crushing and screening plants. Aggregates for urban construction, gravel and powder are obtained. The aggregates are used in the manufacture of light concrete. Nowadays the possibility of using pumice aggregates in order to obtain light structural concrete is being studied.
