Abstract

A composition is produced by a hydrothermal liquid phase sintering process, and the process includes providing a porous matrix, the porous matrix having a shape, and allowing a component of the porous matrix to undergo a reaction with an infiltrating medium to form a first product, the infiltrating medium including a greenhouse gas, a remainder of the porous matrix acting as a scaffold for facilitating the formation of the first product. The composition includes the first product and the reminder of the porous matrix. The composition has a microstructure that resembles a net-like interconnecting network. The composition maintains the shape of the porous matrix. The composition is free of hydraulic bonds.

Claims

1. A composition produced by a hydrothermal liquid phase sintering process, the process comprising:

providing a porous matrix, the porous matrix having a shape, and

allowing a component of the porous matrix to undergo a reaction with an infiltrating medium to form a first product, the infiltrating medium including a greenhouse gas, a remainder of the porous matrix acting as a scaffold for facilitating the formation of the first product,

wherein the greenhouse gas is carbon dioxide,

wherein the first product includes carbonate,

wherein the composition has a microstructure with an interconnecting network that resembles a net,

wherein the composition includes the first product and the reminder of the porous matrix, and

wherein the composition has a decomposition temperature of at least about 800°

C.

2. The composition of claim 1, wherein the first product is produced by ion substitution, ion addition, disproportionation, or combinations thereof.

3. The composition of claim 1, wherein the first product is produced by precipitation.

4. The composition of claim 1, wherein the composition is a cement.

5. The composition of claim 1, wherein the porous matrix is derived from a powder.

6. The composition of claim 1, wherein the composition has a homogenous microstructure.
