Carbonation: An Efficient and Economical Process for CO2 Sequestration
نویسندگان
چکیده
Naturally occurring carbonation of cement-based materials is a slow phenomenon. Many factors control the rate of carbonation process in cement-based products. A comprehensive knowledge of the major factors controlling the rate of carbonation, and their effects on the properties of the materials subjected to it, is necessary for using this technology for CO2 sequestration. Most of the studies related to the carbonation are limited to its effects on corrosion of reinforced steel, cover depth design, and service life prediction of reinforced concrete structures. The possibility of using carbonation process as a direct means for carbon dioxide sequestration is yet to be realized. This paper discusses the application of carbonation technique in cement-based products for CO2 sequestration for reducing its concentration in the Earth’s atmosphere. This technology would help cement, concrete, precast products, and other similar industries to reduce the contribution of CO2 emission generated by them.

The potential environmental effects of increasing atmospheric CO2 levels are of major worldwide concern. One alternative for managing CO2 emissions is carbon sequestration: the capture and secure confinement of CO2 before it is emitted to the atmosphere. Successful technologies must be environmentally benign, permanent, economically viable, safe and effective. As a result, their timely developm...

Carbon sequestration by reacting naturally occurring Mg and Ca containing minerals with CO2 to form carbonates has many unique advantages. Most notably is the fact that carbonates have a lower energy state than CO2, which is why mineral carbonation is thermodynamically favorable and occurs naturally (e.g., the weathering of rock over geologic time periods). Secondly, the raw materials such as m...
