Systems and methods for making gypsum board using a liquid gypsum set accelerator. Stucco and water are mixed to form a gypsum slurry, such as in a pin mixer. A gypsum set accelerator is mixed with a liquid medium to form a liquid gypsum set accelerator, such as in an eductor. The liquid gypsum set accelerator is added to the gypsum slurry, which is shaped to form the gypsum board.

Embodiments of the invention generally relate to apparatus and methods to control the addition of moisture to materials for the production of concrete.

An apparatus for delivering a wet concrete mix to a product mold, where the apparatus comprises a hopper configured to retain a fresh concrete mix, a source of treated water having a concentration of nanobubbles of a gas at least double a natural concentration of nanobubbles of the gas within a natural state of the water, a water transport coupling the source of treated water with the hopper, a valve interposed within the water transport for selectively releasing the treated water into the hopper, and a mixer in communication with the hopper for mixing the treated water with the fresh concrete mix to yield an infused wet concrete.

A nanobubble-infused liquid is mixed into a dry concrete mix to form an infused wet concrete, where the nanobubble-infused liquid includes a concentration of nanobubbles of a gas at least double a natural concentration of nanobubbles of the gas within a natural state of the liquid. The nanobubble-infused liquid is preferably liquid water infused with a desired concentration of carbon-dioxide (CO.sub.2) nanobubbles sized within a certain prescribed range. The infused wet concrete is then transported to the mold of a concrete products forming machine to form a molded product that has enhanced qualities including increased carbon capture within the resulting concrete product, improved curing times, increased flowability, self-healing, and improved release from the product mold.
