A membrane roofing system that includes a waterproof layer that protects an insulation layer and a granule coupled to the waterproof layer. The granule has a 60% or greater reflectivity that reduces transmission of ultraviolet light to the waterproof layer. The granule is coated in a fluorinated acrylic copolymer that resists adsorption and absorption of asphaltic chemicals by the granule from the waterproof layer.

Described are cementitious reagent materials produced from globally abundant inorganic feedstocks. Also described are methods for the manufacture of such cementitious reagent materials and forming the reagent materials as microspheroidal glassy particles. Also described are apparatuses, systems and methods for the thermochemical production of glassy cementitious reagents with spheroidal morphology. The apparatuses, systems and methods make use of an in-flight melting/quenching technology such that solid particles are flown in suspension, melted in suspension, and then quenched in suspension. The cementitious reagents can be used in concrete to substantially reduce the CO.sub.2 emission associated with cement production.

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.

Embodiments may include a coated granule for roofing systems. The coated granule may include an aluminum silicate granule and a coating disposed on the aluminum silicate granule. The coating may include a copolymer and a siloxane-based or a silane-based compound. The copolymer may be a cationic fluorinated (meth)acrylic copolymer. The aluminum silicate granule may have a particle size in a range from 0.2 mm to 2.4 mm. The aluminum silicate granule may have a 65% or greater reflectivity. The coated granule may repel oil and maintain its reflectivity better than with other techniques.

Corrosion-resistant refractory binder compositions may be formed with a calcium ion source, high-alumina refractory aluminosilicate pozzolan, and water. Any one or more of such components may individually be non-cementitious. Examples of high-alumina refractory aluminosilicate pozzolan include crushed firebrick; firebrick grog; and mixtures of silicate and any one or more of corundum, high-alumina ceramic, and bauxite; refractory mortar; fire clay; mullite; fused mullite; and combinations thereof, among others. A binder composition may be mixed with sufficient amount of water to form a slurry, which slurry may be introduced into a subterranean formation (e.g., via a wellbore penetrating the subterranean formation). A plurality of the non-cementitious components may react in the presence of water when exposed to suitable conditions so as to enable the binder composition to set. Such compositions, once set, may exhibit enhanced corrosion and/or heat resistance as compared to other binder compositions.

One inch paver tiles may now be set over a concrete pad for use by vehicular traffic. The method and dry concrete mix may be used to overlay concrete driveways. The paver tiles may be laid over a dry concrete mix comprising a latex polymer, Portland cement, sand and a hydration control agent. After laying the paver tiles in a field over the concrete mix in the dry state, a border of paver tiles or other material may be laid in a wet concrete mix prior to hydrating the field paver tiles. The dry concrete mix cures after hydration to form a strong layer adhering the paver tiles to the concrete pad for use by vehicular traffic.
