Composite binders with an SiC content from 10 to 40% are prepared on the basis of high-alumina chamotte and silicon carbide powder previously dispersed in water. Ceramic concretes are prepared based on highly concentrated ceramic binder suspensions (HCBS) and mullite polydispersed filler by vibration casting and their properties are studied. Specimens containing 15% SiC have maximum strength in compression (150 MPa) with a firing temperature of 1200°C. Depending on firing temperature (1200 and 1400°C) and SiC content specimen weight gain specifying the degree of SiC oxidation is in the range 0.2 – 2.6%. Increased heat resistance for specimens containing 10% SiC in the matrix system is established.
