an integrated mixer and nozzle device for a 3D printer of building construction components includes: a support; a mixer disposed inside the support to mix a first material and a second material together to produce a flowable mixture; a conveyor directly connected to the mixer to convey the flowable mixture in a first direction; and a nozzle directly connected to the conveyor to extrude the flowable mixture and to discharge the extruded mixture in a second direction different from the first direction.

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 can include a dry powder mixing tank, a first powder input, a second powder input, a powder output, and a detection device. The first powder input and the second powder input can introduce powders containing different substances that become mixed in the dry powder mixing tank. The detection device can detect information about amounts of different substances in a blend of powder moved out of the tank by the powder output. In some aspects, portions of the blend that do not satisfy parameters for the blend can be diverted from a receptacle for the blend based on the detected information.

A system and process for mixing and distributing building materials. This system and process can also include a way or a means for calibrating the mixing of these materials. This system and process can also include a system for tracking the materials that flow through the system, and for controlling the type of material used in the system.

In some embodiments, a method may include preparing building forms including at least some cementitious materials. The method for preparing forms may include mixing substantially dry cementitious material particles with closed cell foam particles to form a substantially dry composition. In some embodiment, at least some of the cementitious material particles may adhere to at least some surface deformations on the surface of the closed cell foam particles. In some embodiments, the method may include mixing a second portion of water with the substantially dry composition for a second period of time to form a partially wet composition. In some embodiments, a method may include forming a building form including at least some cementitious materials from the partially wet composition. In some embodiments, the closed cell foam particles may include expanded polystyrene. In some embodiments, a ratio of the water to cementitious material particles may range from 0.20 to 0.40.

Techniques or processes for efficiently producing concrete using dynamic feedback are disclosed. A concrete plant can use a control system to manage concrete production based on the dynamic feedback. The dynamic feedback can control mixing of concrete ingredients so as to yield uniform particle distribution for the concrete ingredients. The dynamic feedback can also avoid overflow situations as well as yield improved loading of the resulting concrete into a concrete transport vehicle (e.g., concrete truck).

There is disclosed a system for depositing building materials comprising a motor vehicle, a container comprising a material depositing system and at least one device for removing the container from the motor vehicle. The device can comprise one or more outriggers which are adapted to remove the container from the motor vehicle and which can be used to deposit the container on a job site, There is also disclosed a process as well, which includes at least one of the following steps providing a base slab floor; bull floating the base slab floor, inspecting the base slab floor for debris, utilizing a measuring device to survey height dimensions, applying an adhesive intermediary, inserting plastic pins with respect to survey measured points, mixing a self leveling compound, pumping the mixed compound through a conveying system, and smoothing the mixed compound to create a uniform surface and floor which is cured.

A system and process for mixing and distributing building materials. This system and process can also include a way or a means for calibrating the mixing of these materials. This system and process can also include a system for tracking the materials that flow through the system, and for controlling the type of material used in the system.

A quality assurance system for mixing a slurry comprising at least water or other liquid and at least one flowable wet or dry mass, such as cement, sand or other suitable component, has computerized control over the loading of ingredients and has an accurate and broadly variable speed control of the loading of the ingredients. The mixing chamber has scales that provide a signal indicating the current weight of an ingredient in the mixing chamber. The broadly variable control of the loading rate of the ingredients allows more accurate control of the final weight of each ingredient added. A damping period allows system vibrations to dissipate, allowing highly accurate weights to be measured. Accurate records of the addition of each ingredient are maintained using the internal computer that controls the invention.

A plant for conveying material for the production of structural concrete comprises a first container configured to contain a first amount of material, a first detection member configured to detect a variation in the first amount of material and first release members configured to enable and/or disable release of the first amount of material towards a mixing area of the first amount of material. The plant further comprises a second container configured to contain a second amount of material varying between a second minimum and a second maximum reference amount, a second detection member configured to detect a variation in the second amount of material and second release members configured to enable and/or disable release of the second amount of material towards a mixing area. In particular, an unloading opening of the second container is connected to the mixing area, whereas an unloading opening of the first container is connected to a loading opening of the second container or to a mixing area. A control unit is configured at least to enable said release members to release the first amount of material when the second detection member detects the reaching of the second minimum reference amount in the second container. The present invention also relates to a process for conveying material for the production of structural concrete.
