    摘要: 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.

    摘要: 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.
