1. A method of curing a concrete product, the method comprising:
obtaining a concrete product defining a cavity and an opening leading into the cavity, the cavity peripherally bounded by an inner surface of the demolded concrete product, the concrete product being a demolded concrete product, wherein the inner surface of the demoulded concrete product is exposed to the cavity and an outer surface of the demoulded concrete product is exposed to an environment outside the demoulded concrete product;
positioning the demolded concrete product on a base;
sealing the opening using a cover plate supported by the demoulded concrete product;
introducing carbon dioxide (CO2) gas into the cavity to execute carbonation of the demolded concrete product, thereby exposing the inner surface of the demolded concrete product to the CO2 gas; and
in response to the demolded concrete product attaining a target specification, unsealing the opening.
