YALI® - Volcanic pumice
YALI® is a pure natural material of volcanic origin, free from organic or inorganic contaminants.Each YALI® particle contains very fine pores. This porous structure gives YALI® a low dry bulk density, depending on the grading, of approximately 610 kg/m3 to approximately 800 kg/m3. The average particle strength is 21,2 kN. YALI® thus stands out for its weight, particle strength and white colour.
YALI® formed during a volcanic eruption on the island of Nysiros. The hot volcanic material was initially thrown into the sea, where it was ‘quenched’ and abruptly cooled. This sudden cooling changed the structure of the pumice, giving it pozzolanic properties. This pozzolanic property distinguishes YALI® from all other slowly cooled types of pumice and makes it an ideal aggregate for all cement-bound products.
The YALI® deposit on the island of Giali still contains approximately 90 million tonnes today. The mine's production and loading facilities can, in a very short time, extract thousands of tonnes of YALI® of consistent quality, screen it, store it and load it. YALI® can thereforebe used in large quantities in building construction, civil engineering, road construction, hydraulic engineering, landscaping and horticulture, including major projects. YALI® gradings can be found here.
The YALI® brand is protected as European Community trademark No. 004933008 for building materials, pipes (not of metal) for building, asphalt, pitch and bitumen, transportable buildings (not of metal) and monuments (not of metal) that consist of, or are manufactured using, pumice from the island of Gyali.
