Process The manufacture of concrete is fairly simple. First, the cement (usually Portland cement) is prepared. Next, the other ingredients—aggregates (such as sand or gravel), admixtures (chemical additives), any necessary fibers, and water—are mixed together with the cement to form concrete. The concrete is then shipped to the work site and placed, compacted, and cured. Preparing Portland

Concrete Design & Production Portland Cement
Concrete does not even necessarily have to be directly exposed to the atmosphere for this process to occur. Underground concrete piping and foundations can absorb CO 2 from air in the soil, and underground and underwater applications might absorb dissolved carbon dioxide (carbonates) present in groundwater, freshwaters and saltwaters. Read more on carbon dioxide and concrete. Recycled
Concrete and Sustainability GreenSpec
Concrete's long life means that is more likely that a concrete building will come to the end of its life because no further use can be found for it, rather than a case of the concrete having failed due to age. In these cases, demolition is not always the automatic course. Structures can often be stripped back to their concrete core, then rebuilt to new, contemporary specifications. The
