Provided are a structural energy-saving, heat-insulated and decorative integrated plate and a manufacturing method therefor. The method includes: step 1: welding outer side keels, an inner side keel and a bottom keel into a wall framework; step 2: fixing an inner side decorative plate and an outer side decorative plate on the wall framework through shoot nails, and a hollow structure formed by the inner side decorative plate, the outer side decorative plate and the wall framework being a filling and pouring layer; and step 3: grouting the filling and pouring layer, to form a wall filled with cement foamed polystyrene particles. The present invention features a rational structure, manufactures an integrated wall plate with decorated inner and outer sides, and can replace patterns on the decorative plates. The integrated plate features energy saving, environmental friendliness, shock resistance, compression resistance, fire prevention, heat insulation and sound insulation.

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.

Mineral fines reduce OPC content in concrete, mortar and other cementitious compositions, typically in combination with a pozzolanically active SCM. Mineral fines can replace and/or augment a portion of hydraulic cement and/or fine aggregate. Mineral fines can replace a portion of cement binder and fine aggregate as an intermediate that fills a size void between largest cement particles and smallest fine aggregate particles. Supplemental lime can enhance balance of calcium ions in the mix water and/or pore solution. Supplemental sulfate can address sulfate deficiencies caused by high clinker reduction, use of water reducers and/or superplasticizers, and SCMs containing aluminates. Concentrated or pure carbon dioxide (CO.sub.2) can be used to passivate alkaline values in highly alkaline materials, such as concrete washout fines, CKD, class C flyash, incinerator ash, bottom ash, or biomass ash. CO.sub.2 passivation or sequestration can be carried out before, during or after forming an initial concrete mix.

The present invention provides a fiber-reinforced cement composition comprising; cement, fiber, silica, filler, expanded perlite, and polymer. The fiber-reinforced cement composition according to the present invention has low density, high toughness and flexural strength, and not contains volatile composition. When it is molded into workpiece, the workpiece is lightweight, easy to be cut and/or lathed into desired shapes, drilled and fixed with screws and/or repeatedly nailed at the same position, tolerant to humidity, termites and insects, inflammable and does not produce powder when cut, drilled and/or lathed that is hazardous to the workers. Therefore, it is suitably applicable for being utilized as a material for manufacturing furniture parts.

Embodiments of the present invention may provide encapsulation of waste (2) materials in a first (1), double (5), triple (7), or even quadruple (44) encapsulation. Encapsulation may include waste (2), ash (4), Portland cement (3), water, chemicals, or the like. Agglomerates formed perhaps with high energy mixing may be processed, cured, or the like.

Carbon dioxide and ash are two major waste by-products from coal fire production. Presented herein is are methods, material, and devices for storing carbon using high ash-content building material. The idea is to generate materials with commercial values to offset the cost for carbon capture. Ash with alkali activator (geopolymer) concrete has been studied extensively for its superior performance (higher strength) than ordinary Portland cement (OPC) concrete. However, most geopolymer concrete needs energy input in the forms of pressure and heat, which in turn are usually based on electricity produced through power plants.
