Granules for a roof coating, wherein said granules comprise particles that have a coating, wherein said coating comprises at least one layer of an inorganic powder in a binder, wherein said inorganic powder has a d50 grain size of from 0.5 to 25 μm, and wherein a hydrophobizing and/or oleophobizing agent is present on said coating.

The present disclosure relates to roofing granule having a base granule with at least one layer on the base granule that includes hollow glass spheres embedded in a ceramic matrix and a roofing article having a substrate and a plurality of any embodiment of roofing granules described above. The disclosure additionally relates to a roofing granule precursor mixture containing base granules, an aluminum silicate, an alkali metal silicate, and hollow glass spheres. The disclosure also relates to a method of making roofing granules including providing base granules; applying a coating containing hollow glass spheres, an aluminum silicate, an alkali metal silicate to the base granules; and heating the coated granules to a temperature between about 550° F. and about 1000° F.

Disclosed is a non-sintering method for preparing an artificial cobblestone from dredged soil, comprising the steps of: (1) preparing raw materials; (2) proportioning four types of materials; (3) preparing high-strength non-sintering ceramsite; (4) preparing a cobblestone core; (5) preparing a primary product of the cobblestone; (6) polishing; (7) curing; and (8) forming a finished product. In the method, the dredged soil is used as the raw material to prepare the artificial cobblestone with a core-shell structure, so that an application range of dredged soil recycling utilization can be widened, and a method for preparing artificial cobblestones is provided. By employing the non-sintering method for preparation, the energy consumption for production is low, and a decorative effect of the cobblestone can be achieved.
