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.
Claims21
1-22. (canceled)
An agglomerated particle comprising:
- (a) a plurality of fragments of at least one of a rock, a mineral, or a combination thereof;
- and
- (b) a binder,
- wherein the plurality of fragments of the at least one of a rock, a mineral, or a combination thereof comprises fragments having a particle size passing US Mesh 100 but retained by US Mesh 270,
- wherein the agglomerated particle is an agglomerated particle configured to be applied to a sheet to form a roofing product,
- wherein the at least one of a rock, a mineral, or a combination thereof comprises at least one of basalt, metabasalt, andesite, rhyolite, or a combination thereof, and
- wherein the binder is present in the agglomerated particle in an amount of not more than 8 wt %.
A plurality of agglomerated particles, each of the plurality of agglomerated particles comprising:
- (a) a plurality of fragments of at least one of a rock, a mineral, or a combination thereof;
- and
- (b) a binder,
- wherein the plurality of agglomerated particles have a particle size distribution including at least 7 wt % passing US Mesh 100 but retained by US Mesh 140,
- wherein each of the plurality of agglomerated particles is an agglomerated particle configured to be applied to a sheet to form a roofing product,
- wherein the at least one of a rock, a mineral, or a combination thereof comprises at least one of basalt, metabasalt, andesite, rhyolite, or a combination thereof, and
- wherein the binder is present in the plurality of agglomerated particles in an amount of not more than 8 wt %.
A plurality of agglomerated particles, each of the plurality of agglomerated particles comprising:
- (a) a plurality of fragments of at least one of a rock, a mineral, or a combination thereof;
- and
- (b) a binder,
- wherein the plurality of agglomerated particles have a particle size distribution including at least 4 wt % passing US Mesh 140 but retained by US Mesh 200,
- wherein each of the plurality of agglomerated particles is an agglomerated particle configured to be applied to a sheet to form a roofing product,
- wherein the at least one of a rock, a mineral, or a combination thereof comprises at least one of basalt, metabasalt, andesite, rhyolite, or a combination thereof, and
- wherein the binder is present in the plurality of agglomerated particles in an amount of not more than 8 wt %.
