Zusammenfassung:FIELD: manufacture of building materials. SUBSTANCE: raw meal contains 77.5-80% of Cambrian lumpy clay from deposit Tsekalovsky, 12-15% of mortar sand with fineness modulus 2-2.5, and 5-95% of combustible fibrous additive (cellolignin) with moisture content 4-6% and dispersity 0.5-1 mm. EFFECT: reduced specific weight and heat conductivity of brick at the same or higher compaction strength. 1 tbl
