Agentes ligantes e seus efeitos em concretos refratários alumina-magnésia Binders and their effects on alumina-magnesia refratory castables

Concretos refratários alumina-magnésia são comumente ligados por cimentos de aluminato de cálcio. Estes materiais apresentam, em temperaturas elevadas, uma reação de caráter expansivo decorrente da espinelização in-situ (MgAl2O4). Quando ligados por cimentos, reações adicionais (formação de CA2 e CA...
