ANÁLISE DA UTILIZAÇÃO DA ESCÓRIA NO PROCESSO PRODUTIVO DO CIMENTO

The study carried out analyzed the chemical composition of blast furnace slag, highlighting calcium, silicon, aluminum and magnesium oxides as the main elements present, along with other elements in smaller quantities, such as FeO, MnO, TiO2 and sulfur. The application of slag in Portland cement was investigated based on data from references and bibliographic studies. The results and discussions indicated that the addition of slag in the manufacture of cement resulted in significant benefits, such as savings in grinding energy and a better distribution of clinker phases. Tests carried out on a raw mix containing 37% ground slag showed changes in the kinetics of clinker formation, highlighting the importance of the composition and proportion of slag used. Crystalline blast furnace slag was found to be more suitable than glassy slag for cement manufacture, due to its potential to improve operation and conserve energy. However, further studies and analysis are needed to fully assess the impact of slag on the durability and efficiency of cement, as well as to determine the best conditions of use. In summary, the study pointed out that the use of slag in the manufacture of cement brings relevant benefits,but highlighted the need for further research to confirm and expand the results obtained. The discussion emphasized the importance of considering the limitations of the study and discussing the implications of the findings for the field of study in question.
