Sustainable Use of Steel Industry Slag (SIS) for Concrete Production: A State Art of Review ()
ABSTRACT
This paper presents a review on the sustainable use of steel industry
slag (SIS) in the construction industry for sustainable development. This issue
also may contribute significantly to attain the sustainable development goal
(SDG). If feasible sector is not determined earlier for the use of SIS for the
country like Bangladesh then the unproductive uses will be increased and as well
without large-scale utilization, direct dumping of SIS will create
environmental hazards. On the other hand, the sustainable use of SIS in
concrete production can contribute to the economic growth of the country; in
addition, it can also contribute to keeping our natural environment safe from hazardous
pollution. Another observation of this study is SIS used in cement and concrete
production as aggregate or as additional cementing materials has a long-term
strength and durability. Besides, replacement of cement with SIS deferred the
hydration reaction at early ages, without any significant troubles.
Furthermore, it can also be mentioned that high replacement of SIS with cement may raise a problem of volume
instability which can be solved by using ground-granulated blast-furnace slag
(GGBS) as combined admixture and the slump problem of concrete mixtures can be
adjusted with addition of copper slag or class F fly ash. Feasibility analysis
of SIS usage and an awareness program for all the stakeholders may be
implemented for the sustainable uses of SIS. Both of these will play a vital
role to safeguard environment in addition to economic growth of the country.
