AERATED COMPOSITE MATERIALS, METHODS OF PRODUCTION AND USES THEREOF

摘要

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.

1. An aerated composite material comprising:
a plurality of bonding elements, wherein each bonding element comprises:
a core comprising primarily calcium silicate,a silica-rich first or inner layer, anda calcium carbonate-rich second or outer layer; a plurality of filler particles having sizes of about 0.1 μm to about 1 mm; and a plurality of voids, wherein
the plurality of bonding elements and the plurality of filler particles together form one or more bonding matrices and the bonding elements and the filler particles are substantially evenly dispersed therein and bonded together; andthe plurality of voids are bubble-shaped and/or interconnected channels account for from about 50 vol. % to about 80 vol. % of the composite material, wherebythe aerated composite material exhibits a density from about 300 kg/m3 to 1500 kg/m3, a compressive strength from about 2.0 MPa to about 8.5 MPa, and a flexural strength from about 0.4 MPa to about 1.7 MPa.
