The advantage of cement-free refractory concretes of the ceramic concrete type compared with low cement types consists in the absence of certain components (VGTs) which impair the properties of the compositions. Certain technological features are characterized for the production of ceramic concretes. A process has been developed for obtaining VKVS with semicontinuous (pulsation) loading, providing an increased productivity and a reduced energy expenditure. Examples are given of the effective service of ceramic concretes as refractories for lining steel melting furnaces and other heating units. Some properties of concretes with clay bonds, bonds from modifications of ρ-alumina, and silica sol are examined.
