Chemical composition of the samples showed in Table 1.The
major components of all fly ashes were oxides of Si and Al,and var-
ious other oxides.The untreated fly ash (FA),NaOH-treated fly ash
(TFA-NaOH) and HCl-treated fly ash (TFA-HCl) had similar compo-
sitions.But,a portion of calcium oxide (CaO) in the TFA-HCl de-
creased from 9.7% in the FA to 4.4% causing an increased portion
of all other oxides,especially SiO2.The decreased CaO content in
the TFA-HCl was due to the neutralization between HCl and CaO
causing dissolution of CaO.
