Concrete is a hardened building material created by combining a chemically inert mineral aggregate (usually sand, gravel, or crushed stone), a binder (natural or synthetic cement), chemical additives, and water.
Concrete, usually Portland cement concrete, is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently a limebased cement binder, such as Portland cement, but sometimes with other hydraulic cements, such as a calcium aluminate is distinguished from other, noncementitious types of concrete ...
We describe a process for capturing CO 2 from the atmosphere in an industrial plant. The design captures ∼1 MtCO 2 /year in a continuous process using an aqueous KOH sorbent coupled to a calcium caustic recovery loop. We describe the design rationale, summarize performance of the major unit operations, and provide a capital cost .
