Article made of conglomerate material comprising an aggregate comprising granules of expanded glass or expanded ceramic/clay and defining between them intergranular cavities, and a binder. The binder is present in the minimum quantity necessary for coating the expanded glass or expanded ceramic/clay granules, and the intergranular cavities contain only air and are free from filler material. Moreover, the binder is present in a volumetric quantity comprised between 6% and 12% of the total volume of the article.

The invention relates synthetic silicate granules comprising a mixture of SiO.sub.2, Al.sub.2O.sub.3, Na.sub.2O and CaO, which can be obtained by sintering; to their use in manufacturing an agglomerate stone material and to the agglomerate stone material resulting thereof.

A method of forming a lightweight polished concrete and the resulting composition. Calcium sulfoaluminate (CSA) cement and specialized grout may be added to an amount of water in a mixer. The CSA cement, specialized grout, and water may be blended to a smooth consistency. Lightweight aggregates (LWA) may be added to the blended CSA cement, specialized grout, and water to form a mixture. The mixture may be poured over a fiberglass rebar, vibrated, screeded, and allowed to set. The set mixture may be smoothed with float blades. The smoothed mixture may be hardened with metal blades, such that the hardened mixture becomes reflective. A concrete densifier may be applied to the hardened mixture to form the lightweight polished concrete. Optionally, one or more saw cuts may be formed in the lightweight polished concrete and a coating to may be applied to fill the one or more saw cuts.

A method of forming a lightweight concrete block and the resulting structure. Calcium sulfoaluminate (CSA) cement and specialized grout maybe added to an amount of water in a mixer. The CSA cement, specialized grout, and water may be blended to a smooth consistency. Lightweight aggregates (LWA) maybe added to form a mixture. The mixture may be poured into a mold, allowed the mixture to cure, and removed from the mold to form the lightweight concrete block. The lightweight concrete block may have a first side and a second side joined by a plurality of interposing walls, the interposing walls defining one or more inner cavities and one or more outer cavities. The lightweight concrete block may have features that allow for the insertion of fiberglass rebar to aide in stacking and filling to form a wall.

A method of forming a lightweight concrete comprising lightweight aggregates (LWA) made from recycled materials and the resulting composition. The lightweight concrete may be formed by adding calcium sulfoaluminate (CSA) cement and a specialized grout to an amount of water in a mixer, wherein a ratio of the water to the CSA cement is 1 quart to every 10 lbs of CSA cement. The CSA cement, specialized grout, and water may be blended to a smooth consistency. LWA may be added to the blended CSA cement, specialized grout, and water, wherein a ratio of the CSA cement to LWA is 60/40 by weight. The mixture of LWA, CSA cement, specialized grout, and water may be poured over a fiberglass rebar. The mixture may be allowed to cure and before being densified with a lithium densifier.

In a process for manufacturing a component for an emissions treatment unit, green ceramic product is extruded through a die to form an extrusion having a honeycomb substrate structure with an array of parallel, linear tubular cells extending along its length, the cells bounded by walls dividing adjacent cells from one another. A ceramic unit is obtained by cutting off, curing and firing a length of the extrusion a length of the extrusion. Following the firing, a mixture of a flowable, uncured curable material and a particulate metal component is injected from an end of the ceramic unit into selected ones of the cells so as to block the selected cells over at least a part of their lengths while maintaining all of the walls of the ceramic unit. The injected mixture is then cured to render it solid.
