Composite materials, methods of production and uses thereof
The invention provides novel articles of composite materials having hollow interior channels or passageways, or otherwise being hollowed out, and formulations and methods for their manufacture and uses. These hollow core objects are suitable for a variety of applications in construction, pavements and landscaping, and infrastructure.
1. A system for manufacturing articles, comprising,
an envelope or chamber and enclosed therein,
a composite material distributed as a plurality of discrete carbonatable calcium silicate-based concrete objects, wherein the plurality of discrete concrete objects are arranged along a plurality of parallel planes; wherein,
one or more ducts or channels are arranged between or through the plurality of discrete concrete objects forming a fluid transport system within the one or more ducts and channels and with an exterior of the plurality of discrete objects;
optionally, one or more boards on which the plurality of discrete concrete objects are placed;
one or more racks, tarps, walls or panels with planar, flat, convex or concave faces, that form one or more ducts or channels and facilitate a fluid flow profile in the fluid transport system.
2. The system of claim 1 , comprising a fluid distribution component that controls the fluid flow profile of at least a portion of the envelope or chamber.
3. The system of claim 1 , comprising a fluid distribution component that controls the fluid flow profile throughout the envelope or chamber.
4. The system of claim 1 , wherein the fluid distribution component that controls the fluid flow profile throughout the envelope or chamber changes the direction of a gas flow at least once.
5. The system of claim 4 , wherein the fluid distribution component that controls the fluid flow profile throughout the envelope or chamber changes the velocity of the gas flow at least once.
6. The system of claim 1 , wherein the fluid distribution component comprises one or more of fluid inlets, outlets, plenums, or perforated plates, or combinations thereof.
7. The system of claim 1 , wherein the envelope or chamber is made of a material selected from a metal, alloy, plastic, polymer, polymeric composite, ceramic composite, or combinations thereof.
8. The system of claim 1 , wherein the envelope or chamber is made of a concrete material, or, steel, or tarp, or combinations thereof.
