FIELD: chemistry.
SUBSTANCE: invention relates to production of building materials based on phosphogypsum binder. The mixture for making phosphogypsum boards contains, pts.wt: phosphogypsum 83-85; urea-formaldehyde resin 3.2-3.6; marshalite 11.4-13.8; water in an amount required to obtain a mass with standard consistency characterised by flow diameter of 180±5 mm. The mixture for making phosphogypsum boards contains, pts.wt: phosphogypsum 83-85; urea-formaldehyde resin 3.2-3.6; flue ash 11.4-13.8; water in an amount required to obtain a mass with standard consistency characterised by flow diameter of 180±5 mm.
EFFECT: high strength of phosphogypsum boards.
