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.
Claims20
A method of manufacturing a concrete product, comprising:
- mixing a composition including a binder, an aggregate, and water to produce a concrete mixture;
- imparting a form to the concrete mixture to provide a formed intermediate;
- carbon curing the formed intermediate to obtain a cured intermediate until a CO2 uptake of the cured intermediate is 9.9 to 15.4%;
- and
- performing a post-hardening treatment to the cured intermediate by exposing the cured intermediate to a temperature above an ambient temperature to obtain the concrete product.
2 more elements
A method of manufacturing a concrete product, comprising:
- obtaining a carbon cured intermediate having a compressive strength of 15.7 to 51.2 MPa, the carbon cured intermediate made using a binder requiring carbon dioxide for curing;
- and
- performing a post-hardening treatment to the carbon cured intermediate by exposing the carbon cured intermediate to a temperature above an ambient temperature to obtain the concrete product until the compressive strength is increased by 5% to 112%.
