FIELD: chemistry.
SUBSTANCE: in the method of processing cement concrete there is successive depositing on its surface, of a 10% solution of ortho-phosphoric acid or 10-15% solution of colourless phosphate binder and after 2-3 minutes, a 8-12% solution of an iron, or zinc or barium chloride, iron or zinc or barium nitrate, or iron or zinc sulphate.
EFFECT: increased water permeability and frost resistance of concrete, increased degree of whiteness of the processed surface.
