FIELD: refractory materials. SUBSTANCE: material includes magnesia refractory filler (base), 7.5-11.5% of aluminum powder, 18.5-28.5% of ferrophosphorus powder, and 3-9% (above 100%) of liquid binder. Material is designed for use as refractory mortar for laying linings in steel-smelting assemblies and rotary furnaces serving to bake refractory and cement clinkers. EFFECT: increased strength of mortar-to-lining adhesion, reduced porosity and mass hardening time. 2 tbl
