Carbonation of concrete cover of reinforcement as a cause of loss of durability of structures [PDF]
Archives of Civil Engineering, 2023 The article discusses the physical and chemical mechanisms of the carbonation phenomenon itself, as well as points out the synergistic effect of frost destruction and concrete carbonation on reinforced concrete elements.

Carbonation Resistance Classes of Concretes [PDF]
Romanian Journal of Transport Infrastructure, 2021 Abstract Concrete carbonation is a phenomenon that occurs by the penetration into the cement stone of CO2 present in the atmosphere. The phenomenon occurs in the presence of water in which CO2 dissolves, forming carbonate ions, which in turn react with calcium ions in the pores of the concrete, resulting in calcium carbonate (calcite ...

The Institute of Concrete Technology Yearbook: 2022-2023 27th Edition, 2022 This paper addresses some of the key drivers for, and barriers to, the broader uptake of alkali-activated cementitious materials as potentially lower-carbon binders for use in construction, with a particular focus on the UK industry and market. For a material to succeed in practice, it must be able to be produced at sufficient scale and acceptable cost,

Evolution of microstructure and transport properties of cement pastes due to carbonation under a CO2 pressure gradient: a modeling approach [PDF]
, 2015 Most carbonation models only account for diffusion as the main transport mechanism rather than advection. Nevertheless, in the case of concrete used for underground waste disposal facilities, concrete may be subjected to a high hydrostatic pressure and ...

Passive CO2 removal in urban soils:evidence from brownfield sites [PDF]
, 2020 Management of urban brownfield land can contribute to significant removal of atmospheric CO2 through the development of soil carbonate minerals. However, the potential magnitude and stability of this carbon sink is poorly quantified as previous studies ...

CO2 uptake potential due to concrete carbonation: A case study
Case Studies in Construction Materials, 2017 The cement manufacturing process accounts for about 5% CO2 (carbon dioxide) released into the atmosphere. However, during its life cycle, concrete may capture CO2 through carbonation, in order to, partially, offset the impact of its production.

Preliminary Investigation of Carbonation Problem Progress in Concrete buildings of North Cyprus
MATEC Web of Conferences, 2018 Carbonation process is regarded as one of the most critical durability problem in concrete. As a result of carbonation process, the pH level in concrete is reduced and corrosion of reinforcements initiates, yielding significant damage both in ...
