FIELD: construction.
SUBSTANCE: invention relates to construction materials and can be used in production of ceramic construction materials, for example, for bricks. Ceramic mixture contains Cambrian clay, granulated fraction slag 0.6–5 mm, glass microspheres of fractions 15–200 mcm and oil-contaminated soil with oil products content of up to 14 %, with the following ratio of components, wt%: Cambrian clay 59.0–64.0; said granulated slag 24.0–25.0; said glass microspheres 6.0–7.0; said oil contaminated soil 6.0–9.0.
EFFECT: increasing compression strength and bending strength without increasing average density of item, recycling oil-contaminated soil.
