Application of Desulphurization Residue in Cementitious Mortars

Steel residues in general have a high cementing power, which makes them potential substitutes for Portland cement. One of these residues is that of desulfurization, which currently has no technological application. In this sense, the objective of this work was to evaluate the application of this residue in mortars 1:1:6:1.5 (cement:lime:sand:water), as a substitute for cement in percentages of 0, 10, 20, and 30%. The tests carried out were consistency, mass density, compressive strength, water absorption, and porosity, in addition to incorporated air content. The results demonstrate that the application of the residue as a cementitious material is possible, due to the good mechanical parameters obtained.
