Quality Improvement Techniques for Recycled Concrete Aggregate: A review (2019, methodology): “Thiery et al. (2013) studied the carbonation kinetics, including maximum CO2 absorption and absorption rate, of RCA using CO2 concentrations of 10% and 50%.”
Carbonation of concrete: the role of CO2 concentration, relative humidity and CO2 buffer capacity (2016, background): “Moreover, the hydrates carbonate only partially and the amount of CaCO3 formed in the carbonated zone increases with increasing CO2 concentration [18, 35].”
Impact of accelerated carbonation on OPC cement paste blended with fly ash (2015, background): “no significant water transfer occurs by drying in the short run of an accelerated carbonation test), GRAM can also be used to assess carbonation profiles within concrete by measuring the local density increase due to carbonation (CO2 binding) [32, 34, 22, 35].”
Carbonation of cement paste : Understanding, challenges, and opportunities (2016, background): “treatment of recycled concrete aggregate [140, 142-144].”
Investigation of the carbonation mechanism of \{CH\} and C-S-H in terms of kinetics, microstructure changes and moisture properties (2014, background): “As already illustrated in the literature [64, 65, 46, 66, 47], the decomposition of CC is characterized by the presence of three DTG/MS peaks (see Figs.”
