The present invention relates to using aluminium dross, an industrial waste product, to prepare a composition having fire retardant, insulating and surface protecting properties. The composition is prepared by reacting aluminium dross particles with an acid, and subjecting the resultant reaction mixture to a drying process. The composition, and articles prepared from or coated with the composition, have enhanced fire retardant, insulating and surface protecting properties. The invention is useful for preparing building materials for use in the construction industry, and for forming protective coatings. |
