CO2 uptake by carbonation of concrete during life cycle of ...

10%  Oct 21, 2016  The cement manufacturing process has been responsible for about 5 to 7 % CO2 emissions. However, during its life cycle, concrete structures are submitted to carbonation and can uptake part of CO2 emitted during its construction. In order to corroborate this potential, this study applied mathematical modeling to evaluate the performance of compression strength from a 20, 30 and 40 MPa concrete ...

Jun 01, 2017  The cement manufacturing process accounts for about 5% CO 2 (carbon dioxide) released into the atmosphere. However, during its life cycle, concrete may capture CO 2 through carbonation, in order to, partially, offset the impact of its production. Thus, this paper aims at studying the CO 2 uptake potential of the Itaipu Dam due to concrete carbonation of such material.

About this site

Sep 01, 2007  More than 50% of the CO 2 emitted during cement production originates from the calcination of limestone. This CO 2 is reabsorbed during the life cycle of cement based product such as concrete and mortars in a process called carbonation.. The impact that concrete carbonation has in the assessment of CO 2 emissions from cement production has not been fully documented.

Life Cycle Carbon Uptake of the United States Pavement

The probabilistic results of carbon uptake in the use and end-of-life stages of the U.S. pavement network are presented in Figure 2. The median results show that from 2020 to 2050, around 2.8 Mt CO2 uptake is expected from the nationwide network of concrete pave-ments during the use stage of their life cycle
