Self compacting concrete is one of the last developments in the technology of concrete, being studied and improved from the first '70es. Its production is connected with the use of fillers, most of which coming from iron metallurgy, scarsely present on Sicilian territory. So, the aim of the risearch was to realize self compacting concrete using exclusively local filler, particularly the Etna ashes with a strong pozzolanic connotation, pointing out the use of useless at the moment natural resource. The study relates to the verification of the more appropriate mix-designs and the tests on compressive strength of specimens to early curing and after 28 days. Different characterization tests were reported as to evaluate SCC workability and segregation resistance. Finally the contribution to strength resistance of Etna ashes was measured, relating to cement one.

Abstract
Self compacting concrete is one of the last developments in the technology of concrete, being studied and improved from the first '70es. Its production is connected with the use of fillers, most of which coming from iron metallurgy, scarsely present on Sicilian territory. So, the aim of the risearch was to realize self compacting concrete using exclusively local filler, particularly the Etna ashes with a strong pozzolanic connotation, pointing out the use of useless at the moment natural resource. The study relates to the verification of the more appropriate mix-designs and the tests on compressive strength of specimens to early curing and after 28 days. Different characterization tests were reported as to evaluate SCC workability and segregation resistance. Finally the contribution to strength resistance of Etna ashes was measured, relating to cement one.
