Abstract

This chapter describes the research progress on carbon dioxide (CO2) absorption during the production of concrete blocks. The masonry blocks subjected to accelerated carbonation have higher CO2 sequestration compared with that of under weathering carbonation because of the higher CO2 concentration and accelerated carbonation. A wide variety of factors influencing the accelerated carbonation process, such as preconditioning, raw materials, water-to-cement ratio, sand-to-cement ratio and compaction pressure, concentration and pressure of CO2, and post-curing, are discussed. Also, the kinetic model, dimensional stability, and microstructure of concrete blocks after accelerated carbonation are described.
