Abstract
The invention provides novel aerated composite materials that possess excellent physical and performance characteristics of aerated concretes, and methods of production and uses thereof. These composite materials can be readily produced from widely available, low cost raw materials by a process suitable for large-scale production with improved energy consumption, desirable carbon footprint and minimal environmental impact.
Claims9
A process for producing an aerated composite material, comprising:
- forming a wet mixture, wherein the wet mixture comprises:
- water,
- a particulate comprising calcium oxide or silica having a median particle size in the range from about 10 μm to about 1 mm;
- a ground calcium silicate having a median particle size in the range from about 1 μm to about 100 μm, and
- an aerating agent,
- casting the wet mixture in a mold;
- providing conditions for generation of a gaseous product from the aerating agent thereby causing volume expansion of the wet mixture;
- and
- curing the expanded mixture 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 and CO2.
