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 containerized concrete batch plant is disclosed, comprising a container configured to contain a concrete batch plant to permit the transportation of the concrete batch plant. The concrete batch plant comprising one or more aggregate storage silos to receive a plurality of concrete elements. The one or more aggregate storage silos pour the concrete elements onto a conveyor based on quantity determination by a computer via a deductive scale. The conveyor transfers the concrete elements to a two-shaft mixer. An auger-fed hopper has an auger that is directly exposed to the contents inside the two-shaft mixer and transfers the contents inside the two-shaft mixer into the auger-fed hopper. A concrete pump has access to the auger-fed hopper and pumps the concrete inside the auger-fed hopper into a concrete output hose with a concrete output opening. A knuckle crane and/or hydraulic arms holds supersacks above the aggregate storage silos and the two-shaft mixer.

A transportable concrete mixing plant is provided and includes a frame, a mixing drum for mixing concrete, a conveying system having at least one rail for moving a pre-measured quantity of premix concrete to the mixing drum, and a supply hopper for directing the pre-measured premix concrete into the mixing drum. The rail forms a support track that is traversed by the supply hopper, which travels from a dispensing position near the mixing drum to a loading position spaced from the mixing drum. Optionally, a concrete pump dispenses flowable concrete received from the mixing drum and pumps it to a remote location, such as a work site.

A containerized concrete batch plant is provided. The concrete batch plant includes a container configured to contain a concrete batch plant to permit transportation of the concrete batch plant. The container includes opposed ends and structural support members extending along each edge of the container to a top of the container to support a plurality of panels to enclose the container. The batch plant further includes one or more storage silos to receive a plurality of concrete elements. In addition, the batch plant includes a mixer to receive the plurality of concrete elements. The mixer mixes the plurality of concrete elements to provide concrete. The batch plant also includes a hopper to receive the concrete from the mixer. Furthermore, the batch plant includes a concrete pump to pump the concrete out of the hopper.
