Processing of fly ash and associated waste materials as cement replacements

Further materials have been introduced to the study to test their properties against that of the fly ash and their performance as a cement replacement. It was found that applying the STi process to the fly ash produced results comparable to those of the GGBS controls at 33%. This was bettered when the fly ash was subject to a classification process however, the waste element of the fly ash increases. No further benefits were to be had from the inter-grinding of the fly ash when used in concrete
