Abstract
The invention provides compositions and methods directed to carbonation of a cement mix during mixing. The carbonation may be controlled by one or more feedback mechanisms to adjust carbon dioxide delivery based on one or more characteristics of the mix or other aspects of the mixing operation.
Claims2
A method for producing a carbonated cement mix in a mix operation in a cement mix apparatus comprising
- i. contacting a cement mix comprising cement binder and aggregate in a mixer with carbon dioxide while the cement mix is mixing,
- ii. monitoring a characteristic of the cement binder, the cement mix, a gas mixture in contact with the cement mix or the mixer, or a component of the cement mix apparatus;
- and
- iii. modulating the exposure of the cement mix to the carbon dioxide or another characteristic of the cement mix operation, or a combination thereof according to the characteristic monitored in step (ii).
