Annotation: Carbonate-containing rock-forming minerals are one of the most common minerals on the planet. Low acid resistance is the main lack of this group of minerals. A glance on their face disappears in 10-15 years; caverns and cracks appear on marble items, limestone destructs. Waxes and soaks developed recently have an organic basis and retain on the items by penetrating into the pore structure only. When using the sulfate solutions of some metals to change mechanical and ornamental properties of the carbonate rocks, a chemical interaction on the ionic level takes place, the latter being confirmed by the IR analysis. It results in a significant increase of micro-hardness and acid resistance of the carbonates, as well as in a reduction of water absorption of the carbonate rocks. A low cost and a technological simplicity allowed reaching a lower cost of slab face waxing in comparison with foreign compositions.
Keywords: carbonates, rocks, limestone, marble, modification, properties, sulfates.
