A system for applying a building material, including: a first component of the building material, including a first constituent and a second constituent; a second component of the building material; a first mixer for mixing the first constituent and the second constituent; a supply device for supplying the first constituent to the mixer; a movement device for modifying a site of application in a space; and a second mixer for mixing the first component and the second component.

A system for delivering and applying a flowable mixture to an article (311-313) is disclosed. The system includes a mixture delivery system (200) and a skinning system (300). The mixture delivery system (200) includes a mixer (220) configured to mix a dry material and a fluid to produce the flowable mixture, and a pump (235) configured to pump the flowable mixture to a delivery line. The skinning system (300) receives the flowable mixture from the mixture delivery system (200) through the delivery line. The skinning system (300) includes a skinning pipe (310) configured to apply the flowable mixture to the article (311-313) and a manifold (305) that supports the skinning pipe (310). The skinning system (300) also includes an article feeding mechanism (315) configured to push the article (311-313) into the skinning pipe (310). The skinning system (300) includes a transfer system (320) configured to hold the article (311-313) and move the article (311-313) out of the skinning pipe (310).

A mobile industrial mixing apparatus includes a frame, a mixing chamber, a motor, a storage bin, and a transport mechanism. The mixing chamber is coupled to the frame and includes a housing, a top end, and a bottom end, and includes a mixing mechanism disposed within the mixing chamber, the mixing mechanism mixing an industrial powdered bulk material with a liquid. A discharge opening allows a mixture of the industrial powdered bulk material and the liquid to leave the mixing chamber. The motor is coupled to the mixing mechanism and drives the mixing mechanism. The storage bin is coupled to the frame and is disposed proximate to the bottom end of the mixing chamber, the storage bin receiving the mixture of the industrial powdered bulk material and the liquid. The transport mechanism is coupled to the frame and transports the mixing chamber and the storage bin.

An apparatus for inserting and removing a mixer rotor pin includes at least one rotor pin with a transverse bore, as well as a rod dimensioned for slidably engaging the transverse bore. The apparatus also includes a mixer rotor pin insertion and removal tool having a tool body. A bottom of the tool has a slot for selectively engaging the aforementioned rod upon insertion of the rod into the transverse bore, and a top of the tool has a non-circular socket for accommodating a driver tool.

A system for applying a building material, including: a movement device for modifying a site of application in a space; a first component of the building material; a second component of the building material; and a mixer for mixing the first component and the second component, the mixer including a drive and a mixing chamber provided with a stirrer shaft and a conveyor device, the conveyor device being designed as a screw conveyor with windings, and the mixer being adapted to the building material.

Continuous method including mixing water and cementitous powder to form slurry; mixing the slurry and reinforcement fibers in a single pass horizontal continuous mixer to form fiber-slurry mixture, the mixer including an elongated mixing chamber having a reinforcement fiber inlet port, and upstream of the fiber inlet port is an inlet port to introduce water and cementitous powder together as one stream or at least two inlet ports to introduce water and dry cementitous powder separately as separate streams into the chamber, a rotating horizontal shaft/s within the chamber, part of the chamber for mixing the fibers and slurry and moving the fiber-slurry mixture to a mixture outlet; discharging the fiber-slurry mixture from the mixer outlet; forming and setting the fiber-slurry mixture on a moving surface; cutting the set mixture into fiber reinforced concrete panels and removing the panels from the moving surface.

A method in which a stream of dry cementitious powder passes through a first conduit and aqueous medium stream passes through a second conduit to feed a slurry mixer to make cementitious slurry. The cementitious slurry passes through a third conduit and a reinforcement fiber stream passes through a fourth conduit to feed a fiber-slurry mixer which mixes the slurry and discrete fibers to make a stream of fiber-slurry mixture. An apparatus for performing the method is also disclosed.

A mobile volumetric concrete mixing system includes a suction system that vacuums up trench spoils while a trench is being cut. These trench spoils are then screened on-site for particle size to be reused and mixed with water, cement, and/or other admixtures at an auger mixer to form a backfill mixture. This backfill mixture may then be loaded into a hopper that continuously agitates the mixture so that the mixture does not harden before pouring. The agitating hopper is coupled to a discharge chute of the auger mixer and includes one or more augers disposed at various orientations that the backfill mixture is channeled through. From the agitating hopper, the backfill mixture is channeled to an applicator that moves along the trench and that enables the mixture to be quickly poured into the trench with little clean-up required.

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.
