Abstract: A method of manufacturing a concrete product, includes: mixing a composition including a binder, water, and an aggregate to produce a concrete mixture, a major portion of a weight of the aggregate attributed to particles sized to pass through sieve openings of about 2.36 mm; imparting a form to the concrete mixture to provide a formed intermediate; conditioning the formed intermediate to obtain a conditioned intermediate; and curing the conditioned intermediate with a gas containing carbon dioxide to obtain the concrete product.

Abstract: A method of manufacturing a concrete product includes mixing a composition including a binder, an aggregate, and water to produce a concrete mixture, and imparting a form to the concrete mixture to provide a formed intermediate. The formed intermediate is carbon cured to obtain a cured intermediate. A post-hardening treatment to the cured intermediate is done by exposing the cured intermediate to a temperature above an ambient temperature to obtain the concrete product.

Abstract: A method for making a carbonated precast concrete product includes: obtaining a mixture including at least one binder material, an aggregate, and water; molding the mixture into a molded intermediate; demolding the molded intermediate to obtain a demolded intermediate, the demolded intermediate having a first water-to-binder ratio; conditioning the demolded intermediate to provide a conditioned article having a second water-to-binder ratio less than the first water-to-binder ratio of the demolded intermediate; moisturizing at least one surface of the conditioned article with an aqueous medium, thereby causing a weight gain of the conditioned article and providing a moisturized product, a first portion of the moisturized product having a third water-to-binder ratio greater than a fourth water-to-binder ratio of a remainder of the moisturized product; and curing the moisturized product with carbon dioxide to obtain the carbonated precast concrete product.

Abstract: A method of manufacturing a concrete product, includes: providing a composition including a binder, an aggregate, and water; mixing the binder, the aggregate, and the water to produce a concrete mixture; imparting a form to the concrete mixture to provide a formed intermediate having a first water-to-binder ratio; and concurrently conditioning and curing the formed intermediate by conditioning the formed intermediate while curing the formed intermediate, wherein the formed intermediate is concurrently cured and conditioned to obtain final water-to-binder ratio less than the first water-to-binder ratio.

Curing the conditioned article may be done within an expandable enclosure.

Abstract: A method of curing a concrete product having a cavity is described and includes positioning the concrete product on a base, sealing an opening to the cavity using a cover plate, introducing carbon dioxide (CO2) gas into the cavity to execute carbonation of the concrete product, and, in response to the concrete product attaining a target specification, unsealing the opening. A system for curing a precast concrete product is also described.

Abstract: The present description relates to methods of producing a wet-cast slag-based concrete product particularly where the wet-cast slag-based concrete product is cast, pre-conditioned and cured with carbon dioxide inside a mould and/or inside a mould placed in a curing chamber. The wet-cast slag-based concrete product is optionally reinforced.
