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.
Claims14
An apparatus for carbonating a cement mix comprising a cement binder and, optionally, aggregate in a cement mix apparatus during a mix operation, comprising
- (i) a mixer for mixing the cement mix;
- (ii) a system for contacting the cement mix in the mixer with carbon dioxide operably connected to the mixer and comprising a first actuator for modulating a flow of carbon dioxide to the mixer through a conduit comprising an opening directed to the mixer;
- and
- (iii) a controller comprising a processor wherein the processor is configured to receive input regarding carbon dioxide flow rate and/or time of exposure and to send output to the first actuator based at least in part on the input.
