Abstract The article deals with the issue of man-made resources utilization in the form of ceramic crushed bricks and production fault with fine and big fillers for small objects production from the ceramic-concrete. This wasteless technology of wall materials production allows saving the environment. There is a peculiarity of preparing forming ceramic-concrete compositions as well as in structures of these compositions. There are formulas of light-weight concretes based on ceramic brick filler and parameters necessary for quality and durable small-piece materials. Such characteristics as density, thermal conductivity, cold resisting property and compression strength have been studied as exactly these characteristics are under special attention. Developed compositions of light ceramic-concretes had rather low thermal conductivity within 0.49–0.98 Wt/(m·°C), ceramic-concrete type by cold resisting property was within F50 to F100 limits, density changed from 1300-1700 kg/m3, compression strength was 41 MPa. Using crushed bricks in light concretes allows reducing the cost by 30–35.
