We would like to buy very fine natural fly ash (spherical particles), chemically suitable for use in concrete (chemically – class F fly ash).

In terms of fineness, we need the mean particle size to be < 7 microns, which for natural fly ash with spherical shape of particles approximately correlates to surface area (m. sq./kg) of:
Blaine fineness >800 ;
BET > 2200;
Laser Diffraction >3000.

If you can supply such product, please send us the product specification.
And let us know your FOB price for 20 ton / bulk bags / in 20ft container (if pallets are used – must be ISPM 15 certified, or plastic)!
