Effect of duration and pressure of carbonation curing on the chloride profile in concrete [PDF]
Revista IBRACON de Estruturas e Materiais, 2023 Carbonation curing alters the characteristics of the concrete's microstructure and can interfere with the penetration of aggressive ions. The objective of this article was to evaluate the influence of CO2 pressure and carbonation cure time on chloride ...

Effect of Different CO2 Treatments on the Metal Leaching in Steel Slag Binders
Frontiers in Energy Research, 2021 Carbonation is an effective method to promote the quality of the steel slag binder. In this article, two carbonation approaches, namely hot-stage carbonation and accelerated carbonation, were employed to leach the metals, and the influence mechanism on ...

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 ...

Carbon···Carbon Weak Interactions
The Journal of Physical Chemistry A, 2009 A theoretical study of the complexes formed by systems with electron-deficient and electron-excessive carbon atoms was carried out using DFT and ab initio methods up to the CCSD(T)/aug-cc-pVTZ computational level. Stable complexes with interaction energies between -6.0 and -22.8 kJ mol(-1) were obtained that correspond to weak C...C interactions.
