A mobile aggregate hopper for a volumetric and gravimetric mixer having arcuate longitudinal walls for holding and isolating aggregate. The mobile aggregate hopper has a base integral with the arcuate longitudinal walls with an aggregate transfer conveyor capable of attachment to a trailer or chassis having wheels. The single sheet structure of the longitudinal arcuate side walls minimizes welding and mechanical joints during manufacturing and provides a hopper with high strength and capacity and low overall weight.

Described is a cementitious material delivery system having at least one material box (10) with a lower access point (16) that is connected to a collection hopper (22). Also described is a cementitious material delivery system having at least one container (38) with an unloading end (42) that is located proximate to a collection hopper (22). The at least one container (38) can be positioned on at least one shelf (18) that can be raised so that the unloading end (42) is tilted toward the collection hopper (22).

An environmental-friendly mortar robot comprises a first, second, third, and fourth container module. The first container module (2) consists of a sand midway silo, a weighing system, a stirring system, and a control system; the second container module (3) consists of a cement silo, a spiral conveying machine, a material level meter and a water storage tank; the third container module (4) consists of a fly-ash silo, a spiral conveying machine, a material level meter and an air storage tank with an air compressor; the fourth container module (5) consists of a sand storage bin, an elevator, a material level meter and an additive storage box. While transporting, the first container module can be respectively detached into four functional modules which are directly put onto a transporting vehicle together with other three container modules for transportation.

Aspects involve estimating transitions in properties of a concrete mixture prior to batching and during transport of the mixture from a first location, such as a concrete batch plant, to a second location, such as a job site and controlling a mixture of ingredients for concrete in response. A tool may execute a method for estimating an initial temperature at batching and a change in temperature of the concrete mixture during transport due to the exothermic reaction of the mixture, percentages and types of ingredients of the mixture, and/or environmental factors along a transit route. A control system at the concrete batching plant may control one or more components of the concrete batch plant in response to the estimated temperature change, such as a dispenser of an ingredient of the mixture and/or a heating or cooling mechanism to adjust the temperature of an ingredient of the concrete mixture.

Systems described herein relate to a mobile material transport system for 3D printing construction. Embodiments of the mobile material transport system include a portable container configured to store a granular material, such as a dry mix mortar. The system also includes a feed system coupled to the portable container that may continuously expel the granular material through a material output valve at a steady feed rate that may be controlled to adjust the feed rate up or down. Additionally, the system may include a power supply that powers the feed system, as well as any additional construction equipment, such as a material mixer or 3D printer.
