Accelerated carbonation as a fast curing technology for concrete blocks

摘要: Abstract This chapter reviews the research progresses on accelerated carbonation curing for concrete blocks. Unlike passive processes, mainly involves reactions between carbon dioxide and main silicate phases, such as tricalcium dicalcium silicate, in presence of water or vapor. Recently, it has gained increasing traction not only because interesting prospect replacing steam to produce environmentally-friendly with low energy consumption, but also its capacity capture store uphill battle combating climate change. More importantly, this technology commands several advantages over traditional moisture terms decreasing duration time early improving mechanical properties dimensional stability concrete. A wide variety influencing factors, cementitious materials, CO 2 concentration pressure, sand-to-cement ratio, compaction preconditioning conditions, further were examined discussed. The importance subsequent hydration under appropriate conditions was highlighted plays an important role degree facilitating development blocks at ages. Also, reaction kinetics, mechanisms, microstructure carbonated introduced. review is supposed serve a vehicle major new hopes shed light future needs.
