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.

A method of retrofitting an existing apparatus for forming concrete products, where the apparatus comprises an existing component located upstream of a product mold and adapted to deliver treated concrete to the product mold, adapts the existing component to treat fresh concrete to be delivered to the product mold by a new component with treated water infused with a concentration of carbon dioxide nanobubbles. The step of adapting comprises adding to the existing component a water delivery system that is configured to direct the treated water into the fresh concrete, where the water delivery system is provided with one or more liquid manifolds configured to dispense the treated water into the fresh concrete to form treated concrete.

A mobile twin shaft mixer is disclosed herein, as well as methods of using the same. A benefit to the mobile twin shaft mixer can be a compact, lightweight, high capacity twin shaft mixer useful for mixing, proportioning, and transporting construction materials in mobile operations. A benefit to the methods of use of the mobile twin shaft mixer can be the supply of modern construction materials to the delivery location at the point of installation.

A Mortar Delivery System is described. The Mortar Delivery System provides precise control of the delivery and application of mortar in addition to the mixing and tempering of mortar. Such control eliminates the use of a hand trowel in brick, block and stone laying applications. Sensing and control are integrated with the Mortar Delivery System to make it an important element of a robotic brick laying system. The Mortar Delivery System contains sensors to measure mortar viscosity and workability, mortar flow rate, and mortar nozzle pressure. The data from the Mortar Delivery System sensors can be used to change the rotational speed of the shear blades, change the amount of water being used for mixing or tempering, and change the delivery speed of the mortar. Such changes result in precise control of mortar that is in turn suitable for automated or semi-automated building processes.

Mixer bucket (1) provided with a hopper (12) having a concave bottom portion (120) provided with an opening (122) arranged between a first and a second continuous portions (124)(126); a funnel-shaped member (30) being carried by the concave portion (120) so as to face the opening (122) and define a gravity discharge for mixture; the funnel-shaped member (30) being carried by the hopper (12) by means of a guide (128) aligned with the given direction (D); actuating means (40) being carried by the hopper (12) to move the funnel-shaped member (30) along the guide (128) between a first position (P1), where it faces the opening (122), and a second position (P2)(P3), lateral with respect to the opening (122) in correspondence of one of the first and second flanks (14)(16).

A bucket assembly for a construction vehicle, having a body with a bottom wall, a rear wall, a first side wall, and a second side wall defining a cavity therein, the first side wall having a discharge outlet. A metering system includes an auger moveably attached to the body along a pivot axis within the cavity. The auger has a motor end and a discharge end. A motor engages with the motor end of the auger and is configured for variable movement of the auger about the pivot axis in a first direction for metered dispensing of a construction material through the discharge outlet, and a second direction for controlled mixing of the construction material within the cavity.

A system and method for placing and circulating concrete is disclosed. The system includes a hopper body, a feed auger, one or more circulating elements, a pump, a valve with two or more outlets, a return conduit, and two or more hoses. The hopper body of the system may additionally include a heat exchanger. Concrete slurry is placed into the hopper body, continuously circulated within the hopper body, and drawn from the hopper body by the pump and conveyed through the hoses, or through the return conduit, or both. Concrete slurry within the hoses may be returned to the hopper body.

A method and apparatus for a mobile twin shaft mixer, which includes a mixing chamber formed of a flexible sheath and a frame formed of a rigid material. A benefit to the mobile twin shaft mixer can be a compact, lightweight, high capacity twin shaft mixer useful for mixing, proportioning, and transporting construction materials in mobile operations. A benefit to the methods of use of the mobile twin shaft mixer can be the supply of modern construction materials to the delivery location at the point of installation.
