摘要：Carbon dioxide (CO2) is the predominant greenhouse gas resulting from anthropogenic activities. A significant fraction of CO2 which is discharged into the atmosphere comes from the point sources of Industry. Cement production alone contributes approximately 7-9% of global CO2 emissions. This emitted CO2, however, can be partially recycled into concrete through early age curing to form thermodynamically stable calcium carbonates. The carbonation reaction between CO2 and appropriate calcium compounds results in permanent fixation of the CO2 in a thermodynamically stable calcium carbonate. CO2 and water can be found in every environment and thus the concrete will be subjected to carbonation. The potential for CO2 absorption in concrete is summarised in this publication. It also emphasizes on the study of optimization of concrete by curing it by using CO2 gas whichcan be beneficially used in the manufacturing of concrete to reduce carbon emissions, increase early strength, and improve the concrete's durability. In accordance with cement content and cement type, carbon uptake in 2 hours, 4 hours, 6 hours and 8 hours will be tested for mechanical and durable properties. Ultimately comparative study will be conducted on concrete curing by conventional method and by carbon dioxide curing method.
