摘要： 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.

摘要： The present description relates to a method of producing a wet-cast slag-based concrete product particularly where the wet-cast slag-based concrete product is partially or completely set inside a mould, pre-conditioned outside of the mould and then cured with carbon dioxide in a curing chamber. The wet-cast slag-based concrete product is optionally reinforced.

摘要： There is provided a method of manufacturing a concrete product. A composition including a slag-based binder, an aggregate, water and an additive selected from the group consisting of calcium chloride, ground eggshells, sodium carbonate, sodium bicarbonate, sodium hydroxide, fine calcium carbonate, calcium oxide, borax, ammonium chloride and combinations thereof, is mixed to obtain a concrete mixture. The concrete mixture is formed into a desired shape to obtain a formed concrete, the formed concrete having a first water-to-binder ratio. The formed concrete is dried to obtain a dried concrete having a second water-to-binder ratio less than the first water-to-binder ratio. The concrete mixture is carbon cured to obtain the concrete product.

摘要： 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.

摘要： 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.
