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.

Disclosed is an apparatus and method for manufacturing high-performance concrete by introducing air into normal concrete and dissipating air, wherein high-performance concrete is formed in a manner in which bubbles, which are to be removed, are added in a large amount together with an admixture to pre-blended normal concrete so that the admixture is uniformly dispersed in the normal concrete using the ball-bearing effect of the bubbles, thus forming mixed concrete, and the mixed concrete is discharged using air at a high pressure of 5 atom or more to thereby shoot high-performance concrete of which the slump, remarkably increased due to the large amount of bubbles, is reduced to fall within the range of slump of normal concrete while dissipating excess air from the mixed concrete.

A concrete mixing carrier, comprising a vehicle chassis and a mixing drum provided thereon. A drum housing of the mixing drum is cubic, supported horizontally on the vehicle chassis, and able to form an unloading state where a front portion is higher and a rear portion is lower; the mixing drum forms a closed drum housing; a feed inlet and a discharge outlet are respectively provided on a rear end plate; a rotary inner drum formed by splicing movable blades is provided in the drum body, and adjacent movable blades have therebetween a movement margin for rotation; each strip-shaped movable blade is supported at both ends by paired rollers respectively; stirring blades overhang towards inside of the drum body, backs of back plates are provided with drive racks, and drive gears, mutually engaged with the drive racks, are provided at corresponding positions of the drum body using a supporting bracket.

Mobile mixing attachments, skidsteers with mobile mixing attachments, mobile mixing devices and related methods are provided. A mobile mixing attachment for use on a skid-steer can include a rotatable mixing drum having a body that forms an internal cavity and having a forward end and a bottom end. The mixing drum can include a mouth at the forward end of the body that provides access to the internal cavity of the mixing drum. The mobile mixing attachment can include a drum chassis configured to hold and rotate the mixing drum and an attachment plate secured to a rear portion of the drum chassis proximal to the bottom end of the body. The attachment plate configured to engage one or more attachment couplers on lift arms of a skid-steer. The mobile mixing device also comprises a scoop comprising a forward scooping lip and a rear loading end positioned in front of the mouth of the mixing drum. The scoop is secured to the drum chassis.

This invention relates to apparatus and method for measurement and monitoring of physical properties of materials, such as liquids, and more particularly to acoustic instruments, methods, and systems that automatically measure air content in real-time within liquids, including concrete, mortar, or other hydratable cementitious mix suspensions using resonant electroacoustic transducers that have their radiating surfaces in contact with the liquid.

A portable mixing apparatus for mixing components is disclosed. The apparatus comprises a container for receiving components to be mixed, a frame for supporting the container in a first orientation for mixing components and a driving assembly couplable with the container for rotating the container. The frame comprises: a first handle for gripping with a first hand of a user, the first handle being disposed above a centre of mass of the portable mixing apparatus, when orientated in the first orientation, the first handle extending forwardly of the apparatus over the container; a second handle for gripping with a second hand of the user while the first hand grips the first handle, the second handle being disposed below the centre of mass of the portable mixing apparatus when orientated in the first orientation, the first and second handle being arranged to enable the user to carry the mixing apparatus and re-orientate the apparatus between the first orientation and a second orientation for emptying the components from the container.

A mixer has a circular housing defining a mixing area for mixing and kneading of a gypsum slurry. A rotary disc is positioned in the housing and rotated in a predetermined rotational direction. A rotary driving shaft cointegrally connected with the rotary disc and a plurality of scrapers are positioned in the mixing area. A slurry discharge port is provided on an annular wall of the housing for feeding the gypsum slurry of the mixing area onto a sheet of paper for gypsum board liner. An opening of the slurry discharge port is divided into a plurality of narrow openings, so that fluid resistance on the gypsum slurry flowing out of the mixing area is increased. An annular basal part rotates integrally with the rotary disc and an inner end portion of the scraper is fixed to the annular basal part.

An extruder includes a receptacle for containing material to be extruded. The extruder further includes a dispersion blade positioned within the receptacle and a nozzle secured to the receptacle. The nozzle defines a first opening positioned within an interior of the receptacle, defines a second opening positioned outside of the receptacle and defines a channel which extends from the first opening through the nozzle to the second opening defining a flow path which extends from the first opening, through the channel and to the second opening. The nozzle extends through a wall of the receptacle and into the interior of the receptacle such that the first opening is positioned spaced apart from the wall.
