Abstract
A manufacturing process of a concrete product includes: (1) extracting calcium from solids as portlandite; (2) forming a cementitious slurry including the portlandite; (3) shaping the cementitious slurry into a structural component; and (4) exposing the structural component to carbon dioxide sourced from a flue gas stream, thereby forming the concrete product.
Claims20
A system for manufacturing a concrete product, comprising:
- a leaching reactor;
- a precipitation reactor connected to the leaching reactor;
- a set of heat exchangers thermally connected to the leaching reactor and the precipitation reactor and configured to source heat from a flue gas stream and transfer residual heat from the flue gas to liquid water feeding the leaching and precipitation reactors.
