Most of the existing research on ferronickel slag has focused on its potential
as aggregate and fine aggregate, this study was conducted focusing on the
potential of ferronickel slag powder as a concrete admixture. For concrete, which
fly ash, blast furnace slag, and FSP were mixed with each 10% type the
reactivity was evaluated by applying ASTM C 1260 of the United States. As a
result, compared with the control group, the expansion rate of fly ash decreased
by 8.43% and that of fine blast furnace slag powder decreased by 14.46%, while
the expansion rate of ferronickel slag decreased by 49.40%. it was confirmed
that ferronickel slag can sufficiently be replaced existing supplementary
cementitious admixtures such as fly ash and blast furnace slag in terms of
suppressing the reactivity of aggregates. However as a result of SEM analysis,
ettringites were generated, and additional research about how it affects concrete
is needed.
