  • Rock fines as carriers of plant nutrients
    Patent number: 12264114
    Abstract: A method comprising (a) obtaining rock fines comprising at least one of basalt, metabasalt, diabase, rhyolite, andesite, meta-andesite, granite, graphite, talc, silica, sand, perlite, or a combination thereof, (b) obtaining a binder, (c) obtaining a material comprising at least one of Ca, Mg, S, B, Cl, Cu, Fe, Mn, Mo, Ni, Zn, or a combination thereof, and (d) combining ingredients comprising the rock fines, the binder, and the material.

  • Building materials comprising agglomerated particles
    Patent number: 12264101
    Abstract: Roofing granules comprising agglomerated inorganic material, and building materials, such as shingles, that include such roofing granules. By fabricating roofing granules from agglomerating inorganic material it is possible to tailor the particle size distribution so as to provide optimal shingle surface coverage, thus reducing shingle weight and usage of raw materials. Additionally, the use of agglomeration permits the utilization of by-products from conventional granule production processes.

  • COATED ROOFING GRANULES, ROOFING MATERIALS MADE THEREFROM AND METHODS OF PREPARING COATED ROOFING GRANULES
    Publication number: 20240392569
    Abstract: This invention relates to coated roofing granules, roofing materials made therefrom, and methods of preparing such coated roofing granules. By coating roofing granules with an aqueous coating that includes water, a silicon-containing oligomer or polymer, and an acrylic resin, coated roofing granules can be prepared that exhibit reduced staining as compared to traditional roofing granules that are treated with petroleum oil.
