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.

Effects of CaO-based expansive agent on carbonation resistance of marine concrete
Case Studies in Construction MaterialsMarine concrete contains a high volume of supplementary cementitious materials, which benefits low-carbon concrete production. However, they may also increase the risk of cracking and accelerate the carbonation due to the pozzolanic reaction ...

Preliminary study of the effect of carbonation curing on geopolymers
Revista IBRACON de Estruturas e Materiais, 2023 Carbonation curing differs from weathering carbonation since it is performed intentionally at the early ages of cement hydration. This cure involves applying different levels of CO2 (5% to 99%) to concrete for a short period of time, usually followed by ...

Carbonation assessment in concrete by nonlinear ultrasound
Cement and Concrete Research, 2011 The carbonation process results in a change in the elastic properties of concrete, resulting in a variation of standard acoustic indicators such as wave speed. However, this evolution is too low to ensure an efficient carbonation assessment. The present communication focuses on the feasibility of carbonation assessment in concrete by applying Nonlinear
