1. 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.
