Methods and an associated system for processing unhardened concrete are disclosed. With these methods, the porosity of the unhardened concrete is significantly increased to decrease the strength so much that it can be easily broken up for sale or reuse. In at least one embodiment, the method includes adding a large volume of foam to the returned unhardened concrete and then mixing the foam with the returned concrete in the ready-mix concrete truck or other concrete mixing devices at any location including the jobsite, enroute to the concrete plant, or at the concrete plant. Through the mixing of foam with the returned concrete, the hydrated cement and aggregate particles are separated by large volumes of air voids, which significantly increase the porosity and dramatically reduce the strength of the returned concrete. The treated concrete is discharged and allowed to solidify in this weakened state, after which it is easily broken into loose particulate material that can be sold or reused.

Methods for improved ceramics component casting. One such method may include vacuuming a ceramic-based slurry mixture and/or vacuuming a component mold. The vacuuming of the ceramic-based slurry mixture and the component mold may be to remove air bubbles from the respective elements. More specifically, the vacuuming may remove air bubbles from the ceramic-based slurry mixture and from a cavity of the component mold, respectively. The method may also include disposing the ceramic-based slurry mixture into the cavity of the component mold, and continuously vacuuming the cavity of the component mold including the ceramic-based slurry mixture for a predetermined time to remove any additional air bubbles included in the ceramic-based slurry mixture. Finally, the method may include forming a ceramic component within the continuously vacuumed cavity of the component mold over the duration of the predetermined time. The ceramic component formed from the ceramic-based slurry mixture. 1. A method comprising: a ceramic-based slurry mixture to remove air bubbles from the ceramic-based slurry mixture, and', 'a component mold to remove air bubbles from a cavity of the component mold;, 'vacuuming at least one ofdisposing the ceramic-based slurry mixture into the cavity of the component mold; andforming a ceramic component within the cavity of the component mold over the duration of a predetermined time, the ceramic component formed from the ceramic-based slurry mixture.2. The method of claim 1 , further comprising continuously vacuuming the cavity of the component mold including the ceramic-based slurry mixture for the predetermined time.3.
