The main conclusions that have been obtained in
this study are related to (a) basic geological and
geotechnical properties; (b) properties as aggregate
of concrete; and (c) properties as granular material
for highways. We conclude that, due to their low
density, high porosity and angular shape, lapilli
particles have a quite different geomechanical
response than other granular natural materials. The
uses we have made of lapilli in the canary islands
could serve as a useful guide for its use in other
volcanic areas of the world. it is especially interest-
ing for regions with recent basaltic lapilli deposits
and a climate that is dry or slightly humid, where
weathering processes are not very intense.
