CLAY-PHOSPHATE MATERIAL Russian patent published in 2024 - IPC C04B28/34 

FIELD: construction materials.

SUBSTANCE: invention relates to construction materials and can be used in production of building blocks in industrial and civil construction. Solution of this task is achieved by the fact that clay-phosphate material containing loam, iron-containing wastes of metallurgical production, containing Fe (II) oxide with residue on sieve No. 008 7%, orthophosphoric acid with density of 1.25 g/cm³, contains mining industry wastes – soapstone, containing, wt.%: Mg₃[Si₄O₁₀](OH)₂ – 40.5, KAl (Si₃Al)O₁₀(OH)₂ – 36.2, SiO₂ – 15.2, (Mg,Fe)₃(Si.Al)₄O₁₀(OH)₂⋅(Mg,Fe)₃(OH)_{6 –} 8.1, with residue on sieve No. 008 7%, with the following ratio of components, wt.%: loam – 40-42, iron-containing wastes of metallurgical production, containing Fe (II) oxide with residue on sieve No. 008 7%, – 6-8, said wastes from the mining industry – soapstone with residue on sieve No. 008 of 7% – 29-31, orthophosphoric acid with density of 1.25 g/cm^{3 –} the rest.

EFFECT: lower thermal conductivity of the clay-phosphate material while maintaining water resistance.
