The present application relates to a method for manufacturing micronized sandstone with a bio-additive, TiO2, and to the thus obtained article, using ceramics or waste material from ceramic manufacture. The waste is ground in several steps and the resulting powders are collected by individual filters and combined in the powder nanomicronizer for subsequent treatment, during which hydrolized or non-hydrolyzed TiO2 is added. This micronized sandstone with the admixture of the bio-additive TiO2 is used to produce joint compounds, grout, mortar, and/or as additive for paints and/or micronized epoxide admixed with TiO2. The micronized sandstone admixed with the bio-additive TiO2 can be additionally subjected to the two optional modalities of the method: treatment with or without the use of a pigment. In order to produce the final article that can be used to produce blocks, floors and other products of various sizes, an agglomerating agent which is also admixed with TiO2 is added to the micronized sandstone admixed with the bio-additive TiO2, either in an aqueous solution or as a dry product, with the addition of coloured oxides, if desired. |
