CO2 curing is widely used in the research of artificial aggregates, and carbonization can improve the performance of artificial aggregates. In addition, fly ash, blast furnace slag and bottom ash from the incineration of domestic waste, which are common solid wastes in the production of artificial aggregates, often contain heavy metals that are harmful to the environment. Carbonization helps reduce the risk of heavy metal leaching from artificial aggregates. It is necessary to quantitatively calculate the degree of carbonization of artificial aggregates as a basis for evaluating the degree of carbonization of artificial aggregates. At present, there is no complete method to quantitatively calculate the carbonization of artificial aggregates, and it is impossible to effectively evaluate the degree of carbonization of artificial aggregates.

The aggregate carbonization degree result is obtained according to the percentage P of the marked part in the cross section.

[0009] Preferably, in the process of obtaining the aggregate cross section, the aggregate cross section to be measured is intercepted by a polygon according to the artificial aggregate cross section photo.

[0010] Preferably, in the process of obtaining the result of the carbonization degree of the aggregate, 1-P is used as the result of the carbonization degree of the aggregate according to the percentage P of the marked part in the cross section.
