FIELD: construction.
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 of 7%, contains a mixture of orthophosphoric acid with spent fixing solution containing, wt.%: Na3[Ag(S2O3)2] – 1.37, NaF – 1.52, NaBr – 1.23, NaI – 0.21, H2O is the rest, having density of 1.22 g/cm3, with the following ratio of liquid components, wt.%: concentrated orthophosphoric acid – 70, spent fixing solution – 30, with the following ratio of components, wt.%: loam 59-61, iron-containing wastes of metallurgical production, containing Fe (II) oxide with residue on sieve No. 008 7% – 4-6, said mixture – the rest.
EFFECT: slowing down the setting time of the clay-phosphate material while maintaining water resistance.
