Abstract

Claims (23)

1 . A kit for retrofitting a ready-mix or precast concrete operation to supply gaseous and solid carbon dioxide to concrete in the operation, wherein the operation mixes concrete in a mixer, comprising

(i) a first conduit configured on a proximal end for connection to a liquid portion of a liquid carbon dioxide container and on its distal end for connection to a carbon dioxide injector unit;

(ii) the carbon dioxide injector unit, comprising

(a) a first carbon dioxide injection orifice,

(b) an internal liquid carbon dioxide input conduit operably connected at a distal end to the first carbon dioxide injection orifice and at its proximal end to a connector for the first conduit, wherein the internal liquid carbon dioxide input conduit comprises a valve proximal to the first carbon dioxide injection orifice, and

(c) a connector, distal to the first carbon dioxide injection orifice, for connecting to a second conduit,

(d) a first pressure sensor for producing a first signal to be transmitted to a first receiver, and

(e) a first temperature sensor for producing a second signal to be transmitted to a second receiver;

(iii) the second conduit, configured on a proximal end to connect with the connector of (ii)(c) and configured on a distal end to connect with a third conduit;

(iv) the third conduit, configured on its proximal end to connect with the second conduit; and

(v) an intermediate processing unit, comprising

(a) the first receiver,

(b) the second receiver,

(c) a processing system operably connected to the first and second receivers, wherein the processing system is configured to process the first and second signals and to produce a first output signal and a second output signal, the first and second output signals based, at least in part, on said processing, wherein the intermediate processing unit is configured to transmit the first output signal to a third receiver in the carbon dioxide injector unit and to transmit the second output signal to a batch control system of the ready-mix or precast concrete operation.

2 . The kit of claim 1 wherein the third conduit comprises a connector on a distal end for connecting to the mixer.

3 . The kit of claim 1 further comprising instructions for assembly of the kit and integration with the concrete operation, wherein the instructions are written, electronic, or a combination thereof.

4 . The kit of claim 1 further comprising a fourth conduit configured at a proximal end to connect with the third conduit and open at a distal end.

5 . The kit of claim 4 comprising fittings for the fourth conduit.

6 . The kit of claim 4 further comprising a fifth conduit configured on a proximal end for connection to a gas portion of a liquid carbon dioxide container and on its distal end for connection to the carbon dioxide injector unit, wherein the carbon dioxide injector unit further comprises an internal gas carbon dioxide input conduit operably connected at its distal end to the internal liquid carbon dioxide input conduit between the valve and the first injection orifice and operably connected at its proximal to a connector for connecting to the fifth conduit.

7 . The kit of claim 6 wherein the carbon dioxide injector unit further comprising a second carbon dioxide injection orifice; a connector, distal to the second carbon dioxide injection orifice for a sixth conduit; and the sixth conduit.

8 . The kit of claim 1 further comprising fittings for the first, second, and third conduits.

9 . The kit of claim 1 further comprising a carbon dioxide sensor for producing a third signal to be transmitted to a third receiver.

10 . The kit of claim 9 wherein the third receiver is contained in the intermediate processing unit.
