Accelerated carbon dioxide sequestration

In this chapter, the mechanism and benefits of accelerated carbonation curing (ACC), the factors affecting the performance of ACC, and the test methods used by the researchers for evaluating the performance of concrete or recycled aggregates subjected to ACC are outlined. Set-ups for conducting ACC of concrete or for carbonating recycled aggregates are described. Some case studies related to the ACC of different types of concrete such as normal concrete and self-compacting concrete and case studies pertaining to the carbonation of recycled aggregates are included. Possible applications of ACC by concrete industries are also highlighted toward the end of the chapter.
