Pozzolane
LAVA pozzolane rock is extracted on Milos island; it is the product of volcanic activity and intense tectonic forces. Thanks to its pozzolanic properties, it can be used in the cement industry and the production of building materials.

LAVA pozzolane rock quality specifications are as follows:
Silicon dioxide SiO2 |
60 - 70% |
Aluminium Oxide Al2O3 |
12 - 15% |
Ferric Oxide Fe2O3 |
2 - 6% |
Calcium Oxide CaO |
2 - 6% |
Magnesium Oxide MgO |
1 - 3% |
Potassium Oxide K2O |
1 - 3% |
Sodium Oxide Νa2O |
2 - 3% |
Titanium dioxide TiΟ2 |
0,2 - 0,6% |
Calcination Loss 950oC |
6 - 10% |
Its specific weight is 1.1 gr/cm3 and moisture content ranges from 14 to 22%.
Sustainable Construction

Sustainable construction aims at limiting buildings' environmental impact, improving at the same time quality when it comes to aesthetics, viability, resistance and durability. Sustainable construction techniques can be implemented throughout a building's life, from the selection of initial materials up to its demolition and material recycling.
Sustainable construction involves in particular:
- Using recyclable materials aiming at preserving natural resources;
- Integrating renewable energy sources into building designing;
- Optimising renewable energy sources.
