Carbon Dioxide Sequestered Concrete
International Journal of Integrated Engineering, 2020 Carbon dioxide, CO2 accounts for most of the emission from all the types of greenhouse gasses in the world. The ability of CO2 to remain longer than other greenhouse gases and the convenience of producing CO2 has resulted in its high projection in a yearly manner. The prime factor for the emission of CO2 are from the actions of human beings.

Effect of autogenous healing of narrow and wide cracks on the progression of carbonation in the walls of cracks [PDF]
MATEC Web of Conferences, 2023 This paper deals with the carbonation of concrete crack walls before and after healing in comparison to the carbonation of the bulk of the concrete. Natural carbonation tests were carried out on 50 MPa concrete.

MODELLING THE CARBONATED CONCRETE REALKALIZATION
JOURNAL OF CIVIL ENGINEERING AND MANAGEMENT, 2009 The presented model of carbonated concrete realkalization is compiled on the basis of the multi‐component medium theory equations. The process equations have been obtained from an analysis of the partial equations of mass, electric charge, momentum, energy, and entropy inequality.

Accelerated and natural carbonation of concrete with high volumes of fly ash : chemical, mineralogical and microstructural effects [PDF]
, 2019 Today, a rather poor carbonation resistance is being reported for high-volume fly ash (HVFA) binder systems. This conclusion is usually drawn from accelerated carbonation experiments conducted at CO2 levels that highly exceed the natural atmospheric CO2 ...
