Various additions are made to concretes of the composition Al2O3–SiC–C in order to improve their operating properties. Results are presented for a study of concrete with addition of organic fiber and Si antioxidant. It is established that in order to accelerate refractory drying made from concrete of Al2O3–SiC–C composition, within which the ratio Al2O3/SiC = 1:1 with an overall content of them of not less than 80%, it is desirable to introduce organic fiber in an amount of not more than 1% in order to create permeable porosity during heat treatment.
