主权项 1. A process for producing an article of an aerated composite material, comprising: forming a wet mixture, wherein the wet mixture comprises: water,a ground calcium silicate, comprising one or more of synthetic wollastonite, pseudo-wollastonite, rankinite, gehlenite, belite, and alite, having a specific particle size, d10 in the range from about 0.25 μm to about 5 μm, d50 in the range from about 5 μm to about 20 μm, and d90 in the range of about 25 μm to about 100 μm,filler particles comprising calcium oxide or silica having a particle size (d50) in the range from about 0.25 μm to about 200 μm, andan aerating agent, casting the wet mixture in a mold; allowing the aerating agent to generate a gaseous product thereby causing volume expansion of the wet mixture; pre-curing the expanded mixture at a temperature in the range from about 20° C. to about 100° C. under an atmosphere of water and CO2 for a time sufficient to result in a pre-cured object suitable for achieving sufficient early-age strength required for de-molding and/or cutting; de-molding and/or cutting the pre-cured object to desired dimensions; and further curing the de-molded and/or cut pre-cured object at a temperature in the range from about 20° C. to about 100° C. for about 6 hour to about 60 hours under an atmosphere of water vapor and CO2 to yield the article.
