  • Publication number: 20150336852
    Abstract: The invention encompasses equipment used to condition a recirculating gas stream in order to cure a CO2 Composite 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.

  • Publication number: 20140361471
    Abstract: A method of preparing and rapidly curing a composite material having a thin cross section. The composite material includes a mixture of solid particles, at least some of which are a material that reacts with CO2, such as a silicate, for example Wollastonite. The green material is prepared by mixing the solid components with a liquid such as water to form a slurry, and forming green bodies by placing the slurry in forms. The green bodies are reacted with CO2 to form cured composite materials having thin sections, in the range of 10 to 15 mm. Curing in periods of 6 hours has been demonstrated.

  • Publication number: 20140314990
    Abstract: 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).
