Landfilled fly ash must first go through a beneficiation process in order to be used in concrete. The project will utilize the Ash-TEK Ponded Ash Beneficiation System (PABS) technology, which consistently produced high quality ash during trials and proved to have a low carbon footprint and an economical operating cost. Lafarge will deploy this ...Web
