Cimento aluminoso e seus efeitos em concretos refratários magnesianos espinelizados in situ

Abstract: O uso de concretos refratários alumina-magnésia ligados por cimento aluminoso (CAC) apresenta vantagens decorrentes da presença de espinélio e de CA6 (CaO.6Al2O3), ambas formadas in-situ e acompanhadas de expansão. Estas fases possuem alta resistência a escórias básicas e ao choque térmico, propriedades estas imprescindíveis para aplicação em panelas siderúrgicas. Estudos anteriores mostraram que o teor de CAC utilizado em concretos alumina-magnésia influencia a expansão do material, principalmente devido à fo… Show more

“…These findings agreed well with what was found in [17]. The phases CA 6 , spinel, and gehlenite identified by XRD analysis indicated that the castables molded with the resin can display good resistance to the thermal shock [14,[16][17][18][19] as it is shown ahead. Fig.…”
