    Abstract: This invention provides a method for stabilization of lead smelter slag and matte subject to acid and water leaching tests or leach conditions by addition of stabilizing agents into the smelter feed such that leaching of lead is inhibited to desired levels. The resultant waste after stabilization is deemed suitable for on-site reuse, off-site reuse or disposal as RCRA non-hazardous waste.

    Abstract: A combination of compositions, products and methods of producing a new type of cement. The cementitious material is created by adding sodium carbonate (also known as soda ash, trona, natron, sodium carbonate decahydrate, sodium carbonate anhydrous, etc.) and one or more rocks or minerals selected from the following—granite, basalt, sandstone or schist. A new method and product are claimed by combining sodium carbonate and one or more rocks or minerals selected from the following—granite, basalt, sandstone or schist and water. The combination of sodium carbonate and one or more rocks or minerals selected from the granite, basalt, sandstone or schist group can be either layered or mixed in a dry or wet state. An exothermic reaction starts after the addition of water to the cementitious material. The composition of the cementitious material can vary between 10% sodium carbonate and 90% of one or more rocks or minerals selected from the granite, basalt, sandstone or schist group to 90% sodium carbonate and 10% of one or more rocks or minerals selected from the granite, basalt, sandstone or schist group. Organic or inorganic additives may be added to the mixture to enhance the composition and/or the final hardened product. The cementitious material or products can be used in a variety of applications not inclusive of forming bricks, interior architecture, table or counter tops, ornaments, repairing damaged cement products, casting, bioabsorbable devices, extruded products, sprayed products, filler, grout, mortar, gunnite, moulded products, composites, cast stonework, agglomerated stone, concrete, hardened products, electronics, packaging and other applications not mentioned above.

    Abstract: A decorative composite stone material, the finished face of which is more durable and requires less maintenance than previous composite stone products. The decorative component of the aggregate material is specifically limited to a hard aggregate of enhanced aesthetic appeal, specifically, to granules of quartz or other transparent or semi-transparent material having a Mohs index of at least 7, naturally occurring or synthetic. The granules of quartz are adjustably coated with a metallic, ceramic, plastic or other film, mixed with a binder, cast, and cured. In the surface finishing step, granules close to the surface are ground to create an exposed facet through which light passes in and out, the coating providing reflective properties that add color, sparkle, glitter, metallic or other visual effect to the hard composite stone surface without compromising the hardness and durability of the product.
