Granules include a blend of porous, mineral-based granules and additional granules having a hydrophobic polymeric coating. Use of the granules as roofing granules is also disclosed. A construction article includes a substrate, an organic coating, and the roofing granules at least partially embedded in the organic coating. Methods of making and using the construction article are also disclosed.

Roofing granules include heat-treated, porous, mineral-based granules having a moisture absorption of at least seven percent by weight and a blend of such heat-treated, porous, mineral-based granules and additional granules having a moisture absorption of less than five percent by weight. Use of the granules as roofing granules is also disclosed. A construction article includes a substrate, an organic coating, and heat-treated, porous, mineral-based aggregate having a moisture absorption of at least seven percent by weight at least partially embedded in the organic coating. A method of making the construction article is also disclosed.

Substrates (e.g., roadways, roofs, walkways) that absorb suns radiation may be undesirably hot (e.g., too hot to use, increased energy costs). Radiation reflecting colored substrates may reduce temperature, but may be impractical (e.g., thickness, use). Radiation reflecting colored coatings (e.g., paints, thermoplastics, polymer coatings, tape) applied on substrate may reduce temperature but have limited lifecycles (e.g., worn off, peel off, lose their color over time). A radiation reflecting colored dry polymer modified cement mixture may be applied as a thin overlay (e.g., thicknesses of approximately ⅛.sup.th inch, thickness between 1/75.sup.th to 1/16.sup.th inch) on the substrate to provide a long-lasting solution for reducing temperature. The dry polymer modified cement mixture is prepared by mixing a dry polymer modified cement blend (ordinary Portland cement, aggregate, polymer powders and pigments) with water. Pigments reduce absorption of radiation including infrared wavelengths and are not limited to lighter colors in visible spectrum of light.

A method of manufacturing a bituminous roofing membrane may include saturating a nonwoven material with a bituminous material to form a bituminous membrane. The method may include applying a first granular material to a top surface of the bituminous membrane. The method may include removing at least some of the first granular material that has not adhered to the bituminous membrane. The method may include heating the bituminous membrane. The method may include applying a second granular material to the bituminous membrane while the bituminous membrane is in a generally planar configuration.

A plurality of granules comprising ceramic particles bound together with an inorganic binder, the inorganic binder comprising reaction product of at least alkali silicate and hardener, wherein the ceramic particles are present as at least 50 percent by weight of each granule, based on the total weight of the respective granule, wherein each granule has a total porosity in a range from greater than 0 to 50 percent by volume, based on the total volume of the respective granule, and wherein the granule has a minimum Total Solar Reflectance of at least 0.7. The granules are useful, for example, as roofing granules.

Some embodiments of the present disclosure relate to a roofing material, wherein the roofing material may comprise a plurality of coated roofing granules, wherein each of the plurality of the coated roofing granules may comprise a roofing granule having an outer surface; and a granule coating, wherein the granule coating is disposed on at least a portion of the outer surface of the roofing granule, and wherein the granule coating comprises graphene.
