One of the greatest issues in today's world is the
elimination of industrial disposal materials. To solve this problem, recycling
waste has become a necessity in many countries according to regulations.
Induction furnaces are systems where the heat is generated by induced currents
by the electromagnetic field. Every production cycle, the system generates 15%
of by-products as slag. In the present study, induction furnace steel slags are
replaced with coarse aggregate at the ratios of 0, 50, and 100% in concrete
samples with 150×150×150 mm size. The Los Angeles abrasion test, compressive
strength test, and density calculations were made. Samples were also subjected
to electronic and optical systems such as SEM, EDX, and XRD to determine the
surface and microanalysis. This experimental study shows that utilizing
induction furnace steel slag increased the physical and mechanical properties
of concrete. The addition of these slags in concrete will allow the efficient
usage of natural resources as well as the production of economical concrete.
Due to their composition, the slags have high abrasion resistance and density
compared to ordinary aggregates. For this reason, increasing the ratio of steel
slags in concrete may result in the formation of heavy concrete.
