This invention relates to manufacturing briquettes, pellets and shapes from recycled asphaltic limestone powder derived from waste residential roofing products. Briquettes and pellets are manufactured through a densification process at varying temperatures, creating recycled asphalt pellets, asphalt limestone pellets and bio mass and coal fines briquettes. Various shapes, including curbs and posts, are manufactured through heat and pressure in molds. Seawalls, walkways and wall panels are manufactured by blending asphaltic limestone powders with polymer resins and extruded or pultruded into shapes.

The present invention relates to cellulose ether compounds for increasing the open time and improving the wettability of cement-based mortars. The inventive cellulose ether compounds are formed from cellulose ether with one or more liquid antifoams incorporated therein. The inventive cellulose ether compounds are preferably used as modified cellulose ether in dry mortars for increasing the open time.

There is disclosed a conductive concrete structure for electromagnetic shielding comprising a first planar surface; a metal mesh positioned on a first face of the first planar surface; and cast concrete positioned on or around the metal mesh. There is also disclosed a method of assembling a conductive concrete structure for electromagnetic shielding. The method comprises positioning a metal mesh comprising a plurality of metal wires on a first planar surface and casting concrete on the metal mesh.

A composite product comprising a metakaolin-based mineral polymer. The composite product has a number of applications including use as a fire resistant material, use as a thermally insulating material and use as an impact resistance material. Methods of preparing a composite product according to the present invention and a kit of parts for preparing the composite product are also disclosed.

A multilayer ceramic substrate that includes a first layer positioned at a surface of the multilayer ceramic substrate, a second layer adjacent the first layer and positioned inward of the first layer, and a surface layer electrode disposed on a surface of the first layer. The first layer has a porosity of 13% or less and a maximum pore size of 10 m or less. The second layer has a porosity of 14% or less and a maximum pore size of 11 m or less.

The disclosure relates to a decorated, surface-structured wall or floor panel and a method for manufacturing same. The decorated, surface-structured wall or floor panel of the disclosure comprises a substrate made of a fiber cement material, a primer coat on a surface of the substrate, a decorative coat on the primer coat, a coat of radiation curable varnish or hot melt on the decorative coat, a structured plastic film on the coat of radiation-curable varnish or hot melt, and a coat of finishing varnish on the structured plastic film.

A composite wall panel comprising a panel frame and an insulating layer disposed therein, and a wall assembly comprising a plurality of the composite wall panels that are vertically jointed to one another. Various embodiments and combinations of embodiments are provided.

The invention is the development of new and unique formulations and mixtures along with unique and improved manufacturing processes for a clear departure for all manufacturing processes in which cement-based formulations and mixtures are commonly utilized in manufacturing SIPS of the prior art and or the teachings of the poured/casted/formed cement based formulations/mixtures and manufacturing processes of the prior art of building/construction industry. The invention serves the current building/construction industry with new and unique formulations and mixtures along with unique and improved manufacturing processes that produce SIPS with enhanced performance characteristics which are unparalleled teachings not present, nor found in any of the prior art.

Disclosed is a foam modifier, e.g., useful for gypsum or cement slurries. The foam modifier comprises a fatty alcohol that is added to a gypsum or cement slurry that includes foaming agent, such as an alkyl sulfate surfactant. The fatty alcohol can be a C.sub.6-C.sub.16 fatty alcohol in some embodiments. The use of such a foam modifier can be used, for example, to stabilize the foam, reduce waste of foaming agent, improve void size control in the final product, and improve the gypsum board manufacturing process.

Gypsum panels, sheathing systems, and methods of making and using the same are provided. A gypsum panel includes a gypsum core associated with a first fiberglass mat having a continuous barrier coating, the coating penetrating a portion of the first fiberglass mat opposite the gypsum core, wherein gypsum penetrates a remaining fibrous portion of the first fiberglass mat such that voids in the first fiberglass mat are substantially eliminated. A building sheathing system includes at least two gypsum panels and a seaming component to provide a seam at an interface between the gypsum panels.
