A product adapted for use as a filtration material, absorption material, or as a pozzolanic material in the production of concrete, is produced from unprocessed sugar mill boiler ash by crushing and optionally screening the unprocessed ash and then grinding the crushed ash. Alternatively, unprocessed ash may be screened to remove particles of a size greater than desired. The grade of the product may be controlled by removing fine particulate material from the ground ash and then recombining the separated materials in desired proportions. |
