Recent Observations on the Characterization of Mill Scale for Potential Application in Construction Industry

The physical and chemical characterization of mill scale is attempted in the current work and the
literature available on the same is compiled as a part of systematic experimental investigations on the
feasibility studies of mill scale as partial replacement of fine aggregates in concrete. The specific
gravity of mill scale is high and can aid in achieving dense concrete. The elemental characterization
by inductively coupled plasma of mill scale indicates the presence of ample iron content, while X-ray
diffractometer studies and Scanning Electron Microscopy confirm these results. It could be concluded
from the preliminary results that fine aggregates can be potentially replaced by mill scale, thereby
providing a sustainable solution to the ever-increasing quantity of mill scale.
