  • Publication number: 20240158300
    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.
    Type: Application

  • Publication number: 20230365473
    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.

  • Publication number: 20230150878
    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.
