Materials characteristics affecting CO2 curing of concrete

The curing degree of the concrete blocks after 2 h of CO 2 curing is shown in Fig. 12. Regardless of which types of aggregate were used, the curing degree of the fly ash-lime based specimen was higher than that of the cement based specimen. This may be due to lime having a larger specific surface area (4850 cm 2 /g) than cement (3519 cm 2 /g).
