ARRIVABENE, Lúcio Flávio et al. Technical feasibility of fabrication of cement agglomerated with granite waste and BOF steel slag. Rem: Rev. Esc. Minas [online]. 2012, vol.65, n.2, pp. 241-246. ISSN 0370-4467. http://dx.doi.org/10.1590/S0370-44672012000200013.
This article studies the technical feasibility of manufacturing cement agglomerated with granite block sawing waste and LD steel slag. The materials were mixed in order to maintain the relationship %CaO / %SiO2 of the mixture equal to 1:2. The mixture was melted and rapidly cooled in water. The sample was characterized and the X-ray diffractograms showed an amorphous material and the presence of mineral phases akermanite and gehlenite, which were considered ideal mineral phases for hydraulic activity. This mixture was added to clinker for cement production. The cement made with this mixture was tested for comparison with the blast furnace slag cement. These results indicate a technical feasibility for manufacturing cement with this mixture.
