The present invention relates to a synthetic mineral composition. The present invention also relates to a method of forming a synthetic mineral composition. The present invention also relates to uses of a synthetic mineral composition.

A composite material, compositions, processes and methods of using coal and coal by-products composite ceramics is provided for use as a safe, non-toxic material for construction, building and architecture components. The composite material disclosed herein is formed from resin/coal aggregates that contain and prevent the release of harmful impurities that naturally occur in both coal and coal by-products while the advantages of coal-based composites are made available to the building industry. The strength, density and porosity of the composites can be tailored within a wide range to fit the final application by controlling the materials, form factor and processing parameters during fabrication.

The present disclosure provides efficient and cost-effective methods for producing synthetic soil and synthetic stone from waste, including inorganic waste and organic waste, through a hydrolysis-polycondensation process.

A reclamation fill stabilizing composition for accelerated soil stabilization of high water-content waste soils/marine mud. The fill stabilizing composition includes a hydrolysis polymerization agent for chemically reacting with water in waste soil/marine mud. A gelling geopolymerization agent chemically and physically locks the water in its formed 3-D aluminosilicate microstructure. A sol-gel immobilization agent chemically and physically traps the water by reacting and bonding with the water. A nano-modification agent provides additional crystal nuclei to increase the effects of hydrolysis polymerization, gelling geopolymerization, and sol-gel immobilization. The reclamation fill stabilizing composition is mixed with high water-content waste soil such as marine mud. The marine mud is rapidly transformed into a compactable fill material within a stabilization curing period as short as 3 hours. Following stabilization, the treated marine mud is compacted (e.g., with a vibratory roller) into a layer of about 240 \~300mm with adequate stiffness (CBR value of at least 15%).

Methods and systems for reclaiming materials from a mixed waste landfill containing coal combustion byproducts (CCBs) are disclosed. The methods and systems can be used to reclaim CCBs from ponds or dry landfills by obtaining mixed waste, crushing the mixed waste to form crushed mixed waste, drying the crushed mixed waste to form dried crushed mixed waste, and combining the dried crushed mixed waste with other compounds to form a blend. The blends can then be incorporated into a cement material, which may be used to form concrete.

Disclosed is a method for manufacturing a hydraulic binder including a calcium aluminate, which involves: a) providing a composition including a lime C source compound and an alumina source compound, the composition including at most 95% lime C and alumina, and at least 23% alumina, by weight relative to the total weight of dry matter of the composition; b) placing the composition provided in step a) in a moisture-saturated environment, at a hydration temperature of between 40° C. and 150° C., so as to precipitate hydrated phases containing at least one aluminium oxide combined with a calcium oxide and with water; and c) subjecting the precipitates obtained in step b) to a baking temperature of between 200° C. and 1300° C., for at least 15 minutes.

Disclosed herein are feedstock materials which can be used for the manufacture of industrial products and consumer goods. The feedstock materials comprise particles of a comminuted paper product having fibrous portions on an outer surface thereof distributed throughout a diagenetically formed mineral aggregate comprising gypsum, syngenite and magnesium hydroxide and/or magnesium sulphate. The feedstock material, and products produced therefrom, is adapted to degrade when buried. Also disclosed herein are methods for producing the feedstock materials, and products produced from the feedstock materials.

Compositions and methods are presented in which aragonite, and especially oolitic aragonite particles are used as infill material in an artificial turf structure or as sub-growth substrate for natural grass. Advantageously, oolitic aragonite particles provide: a superior microporous surface for effective water saturation to impart thermal control and environmental compatibility; ammonia neutralization of urine by reducing urea hydrolysis with the free calcium presented in the aragonite particles; and aragonite particle uniformity allowing for reduced compaction and desirable water draining.
