Physical-mechanical behavior of concrete with the addition of steel waste: a review

At present, the interest of using waste materials and byproducts from concrete has increased, due to the need for minimizing pollution on our planet. The present document aims to systematically review the literature regarding the implementation of steel residues in the concrete mix, and how this influences its physical -mechanical behavior. It has focused mainly on steel residues in the form of slag, filings, shavings, and fibers; incorporated in all types of structural concrete, used in columns, beams, footings, slabs, and walls. The use of these materials has a high impact because it helps reduce the cost of manufacturing cement and concrete, and also provides numerous ecological benefits, such as reducing the cost of landfills, saving energy, and protecting the environment from possible contamination. The indexed articles were searched in the following databases: ASCE, EBSCO, Google Scholar, ScienceDirect, Scopus y SpringerOpen, finally selecting a total of 60 articles published since 2014. Finally, it is concluded that the use of steel waste is an alternative to be incorporated into the concrete mix, since it can partially or totally replace the aggregate, achieving the production of concretes that do not present affection in their physical mechanical properties; and even, in some cases, improving said characteristics.
