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. 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 asphalt mix waste containing, wt. %: SiO₂ – 39.81; CaO – 24.52; Al₂O₃ – 11.95; MgO – 5.78; C_nH_2n-6 – 4.39; Fe₂O₃ – 2.81; Na₂O – 2.32; FeO – 2.24; resins – 1.58; K₂O – 1.48; asphaltenes – 1.23; TiO₂ – 0.87; C_nH_2n+2 – 0.77; BaO – 0.25, with residue on sieve No. 008 7%, at the following ratio of components, wt.%: loam 47-49, iron-containing wastes of metallurgical production, containing Fe (II) oxide with residue on sieve No. 008 7% 5-7, waste of asphalt concrete mixture with residue on sieve No. 008 7% 20-22, orthophosphoric acid with density of 1.25 g/cm³ – the rest.

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