Refractory concretes, ramming compounds, and large refractory blocks are used for the construction of the lining of the heat-using equipment of the metallurgical industry [1; 2, pp. 462-474; 3; 4]. The main adverse characteristics of these materials are inadequate density, loss of strength over a given temperature range, inadequate volumetric stability, the interaction of the binder and filler, loss of refractoriness due to the presence of a binder substance, etc. These Shortcomings can be partly overcome by the use of ceramoconcretes which are heterogeneous polyfractional compositions consisting of a coarse-grained refractory aggregate (50-80 vol. %) the space between the grains being filled with a dispersed ceramic bond ("binder") to give a strong conglomerate. The texture of these materials is "concrete-like~ owing to the "ceramic reinforcement." The aggregate and binder can be of the same or dissimilar nature (i. e., chemical composition and structure).
