A mortar composition, in particular a leveling mortar composition, including: a) 3-45 wt. % of a hydraulic binder, b) 15-80 wt. % of lightweight aggregates, c) 5-50 wt. % of a polymer.

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.

A particulate composition suitable for protection against lightning is disclosed. The particulate composition comprises of a particulate matter comprising a mineral compound, preferably black tourmaline, capable of emitting negatively charged ions continuously, a grinding auxiliary agent, and a liquid medium. The particulate composition is embedded in a substrate, coating or mixed into the granules of composite roofing to protect people, objects and structures from lightning by developing a negatively charged cloaking shield to prevent the attraction of negatively charged lightning from striking. The composition infused or applied on a subject continuously emits negative ions sufficiently producing a protective electromagnetic cloaking shield restricting the wicking action of positive ions up from ground surface and thereby restricting the formation of positive streamers that reach upwards towards the stepped leaders of lightning.

An adhesive composition, in particular a tile adhesive, includes: a) 10-50 wt. % of a hydraulic binder, b) 20-60 wt. % of lightweight aggregates, c) 10-25 wt. % of a polymer.

Particulate high-emissivity (high-ε) refractory products include a mixture of (a) a particulate refractory base material which includes at least one particulate binder material, at least one particulate refractory raw material filler material and optionally at least one refractory additive; and (b) a high-ε pigment in an amount sufficient to impart high-ε properties to the refractory product when cured of at least 0.80. The high-ε pigment is homogenously dispersed throughout the particulate refractory base material and is thereby less susceptible to loss of high-ε properties over time. The particulate high-ε products may be formed into an castable wet mix, an aqueous slurry or an insulating aqueous foam and cured so as to provide a component part of a high temperature refractory structure (e.g., the walls or ceiling of a refractory furnace) having high-ε properties.

Synthetic pozzolans are produced using local materials to provide a cementitious material that is uniform in chemistry and properties independent of the location where the materials are obtained. Two methods of production are described. One is a high temperature process in which materials are processed in a semi-molten or molten state. The second process is a low temperature aqueous process.

Disclosed herein are paver adhesives including dry concrete mixes. The paver adhesive can include cement, silica sand, alumina silicate, and latex or acrylic polymer. The paver adhesive can be configured to be applied to a substrate in a dry state. The paver adhesive can be configured to become hydrated subsequent to pavers being installed over the paver adhesive, and the paver adhesive can be configured to cure and adhere paver tiles to the substrate following the hydrating.
