Specifications

 

Physical characteristics: Thiraiki gi (Pozzolan or Volcanic ash - pumice) comes from Greek islands Milos or Nisiros, and is a main ingredient of the traditional plaster Eco-kourasani.
It is high in active SiO2 (average 55%), the specific weight of the material is 2,4 gr / cm │. The final product 0-75 mm the surface according to Blaine is 7.000 cm ▓ / gr. The content in water soluble alkalis according to ASTM is very low.

-Water soluble alkalis Na2Oeq 0,053%
-Available alkalis Na2Oeq 0,82 %
-LOI 8,3 %


Chemical characteristics of Milos pozzolan:

  SiO2 60 - 70 % TiO2 0.2 - 0,6 %
  Al2O3 12 - 15 % K2O 1 - 3 %
  Fe2O3 3 - 6 % Na2O 2 - 3 %
  CaO 2 - 6 % LO╔ 6 - 10 %
  MgO 1 - 3 %    


Durability & Pozzolans:

-6,5 - 9 ═/mm2 depending on the size of the grain
-7 days > 90% and
-28 days > 99% acc. ASTM C618

Note. Thiraiki gi is a natural product and for that reason, the measurements are indicative.


Eco kourasani is available in more than 30 natural vibrant shades. Please, view the Color Chart
