The invention provides novel paving stones and construction block composite materials and methods for preparation thereof. The paving stones and construction block composite materials can be readily produced from widely available, low cost precursor materials by a production process that involves compacting in a mold that is suitable for large-scale production. The precursor materials include calcium silicate, for example, wollastonite, and particulate filler materials which can comprise silicon dioxide-rich materials. Additives can include calcium carbonate-rich and magnesium carbonate-rich materials. Various additives can be used to fine-tune the physical appearance and mechanical properties of the composite material, such as colorants such as particles of colored materials, such as, and pigments (e.g., black iron oxide, cobalt oxide and chromium oxide). These paving stones and construction block composite materials exhibit visual patterns similar to stone as well as display compressive strength and water absorption equal to or better than that of stone.

Pavers and block composite materials and methods of preparation thereof

The invention provides novel apparatus and processes for gas flow and conditioning to achieve optimal COcuring of articles of composite materials (e.g., precast objects made of carbonatable calcium silicate-based cements), with solid interior or having hollow interior ducts, channels and chambers or otherwise being hollowed out, as well as the precast objects so made, which are suitable for a variety of applications in construction, pavements and landscaping, and infrastructure.

Conditioned curing systems and processes thereof

The invention encompasses equipment used to condition a recirculating gas stream in order to cure a COComposite Material (CCM) and processes that use such equipment to cure the CCM. The gas conditioning equipment allows for a process that controls, reduces or eliminates the rate-limiting steps associated with water removal during the curing of a composite material. The equipment may include, but will not be limited to, control over the temperature, relative humidity, flow rate, pressure, and carbon dioxide concentration within the system; which includes the conditioning equipment, any vessel containing the CCM, and the material itself. Flow rate control can be used as a means to achieve uniformity in both gas velocity and composition.

Method and apparatus for the curing of composite material by control over rate limiting steps in water removal

The invention provides a curing system that is useful for curing materials that consume carbon dioxide as a reagent. The system has a curing chamber that contains the material to be cured and a gas that contains carbon dioxide. The system includes apparatus that can deliver carbon dioxide to displace ambient air upon loading the system, that can provide carbon dioxide as it is needed and as it is consumed, that can control carbon dioxide concentration, temperature and humidity in the curing chamber during the curing cycle and that can record and display to a user the variables that occur during the curing process. A method of curing a material which requires COas a curing reagent is also described.

Curing systems for materials that consume carbon dioxide and method of use thereof

Apparatus and methods for improving the curing process of materials that cure under reaction with COand that do not cure in the presence of water alone are described, and examples are given.

Advanced curing equipment and methods of using same

The invention provides novel railroad ties manufactured from novel composite materials that possess excellent physical and performance characteristics matching or exceeding existing concrete RRTs. The RRTs of the invention can be readily produced from widely available, low cost raw materials by a process suitable for large-scale production with improved energy consumption and more desirable carbon footprint and minimal environmental impact.

Composite railroad ties and methods of production and uses thereof

A method of producing a monolithic ceramic body from a porous matrix includes providing a porous matrix having interstitial spaces, providing an infiltrating medium comprising a solvent and at least one reactive species, and infiltrating at least a portion of the interstitial space of the porous matrix with the infiltrating medium. The solvent is an inert medium that is not chemically reactive with the porous matrix, and is in a liquid phase when in the portion of the interstitial space of the porous matrix. The infiltrating medium is mechanically convected through the porous matrix. The at least one reactive species, when in a portion of the interstitial space of the porous matrix, reacts with a portion of the porous matrix to form a product, and the product fills at least a portion of the interstitial space.

Precursors and transport methods for hydrothermal liquid phase sintering (HLPS)

The invention provides a curing system that is useful for curing materials that consume carbon dioxide as a reagent. The system has a curing chamber that contains the material to be cured and a gas that contains carbon dioxide. The system includes apparatus that can deliver carbon dioxide to displace ambient air upon loading the system, that can provide carbon dioxide as it is needed and as it is consumed, that can control carbon dioxide concentration, temperature and humidity in the curing chamber during the curing cycle and that can record and display to a user the variables that occur during the curing process.
