Carbon dioxide sequestration in cementitious construction materials

Abstract

Addressing global warming now necessitates a focus on “negative emissions,” entailing the extraction of CO2 from the atmosphere. Additionally, legislative actions are encouraging the use of low-carbon materials and addressing embodied carbon within the construction industry, forming essential strategies in the battle against climate change. Recent European initiatives have set the ambitious goal of achieving carbon-neutral buildings by 2030, marking a pivotal stride toward the adoption of sustainable construction materials. Furthermore, endeavors to transform CO2 into valuable products and materials are gaining momentum, potentially unlocking billion-dollar markets in the process. Carbon Dioxide Sequestration in Cementitious Construction Materials, Second Edition, offers an updated and comprehensive overview of carbon dioxide storage-based cementitious construction materials, presenting a promising avenue for substantial eco-efficiency and economic advantages within the construction sector. The first part examines different methods and mechanisms for carbon dioxide sequestration in cementitious materials, including in steel slag, in magnesium-based binders and in autoclaved cement mixtures.
