Abstract
A binder for monolithic refractories characterized by containing ingredients comprised of a chemical composition of at least one of CaxSr1-xAl2O4, and CaySr1-yAl4O7 or these plus 12(CaO)z(SrO)1-z.7Al2O3 (where, 0<x<1, 0<y<1, and 0<z<1) and a binder for monolithic refractories and monolithic refractories superior in erosion resistance to slag or molten iron by monolithic refractories comprised of this binder and refractory aggregates are provided.
