Estudo comparativo de aglomeração em disco rotativo e peletizadora = Comparative study of agglomeration in rotating disk and pellet mill

Resumo: O tema aglomeração é pouco pesquisado de forma aberta em universidades ou instituições de pesquisa, ocasionando uma relativa dificuldade de se encontrar dados gerais sobre os processos existentes. Desta forma, buscando contribuir com o avanço desta área do conhecimento, foram levantados dados e aspectos gerais para a seleção de Leia mais…

Investigation of concrete moisture using no-destructive methods across different compositions and exposure conditions

Abstracts: Studying concrete’s interaction with moisture conditions is crucial for undestanding material degradation and corrosion of embedded steel reinfoircement in structures exposed to atmospheric environments. This work present a comparative assessment of two non-destructive testing (NDT) techniques for moisture evalution: internal moisture measurement with the Moist 210 B (HF SENSOR) Leia mais…

Benefits of incorporating Dy-Cu alloy via the grain boundary diffision process in recycled magnets

Abstract: Nd-Fe-B magnets are a critical material for the green energy transition. However, price volatility makes the supply chain fragile, which makes the recycling process an alternative to reduce dependence on raw materials. Unfortunately, the recycling process introduces oxygen into the magnet, getting worse magnetic properties. Thus, this article studies Leia mais…

Evaluation of permanent embeddable reference electrodes in solution and concrete specimen

Abstract: Monitoring concrete structures is crucial for assessing the corrosion risk of steel reinforcement and optimizing maintenance strategies. This study evaluated the MnO₂/NaOH, Ag/AgCl, and Ti/MMO permanent, embeddable reference electrodes, which are rarely known or used in Brazil for corrosion monitoring. The electrodes underwent assessment tests, immersion tests in solutions Leia mais…
