Comparing the obtained data with previous studies [12], [13], [14] regarding the composition of fly ash generated, the content of CaO is very high due to its lime pre-treatment. With the exception of CaO, the results concerning the percentages of the other main oxides present in fly ash are in close agreement with the previous studies.
