This disclosure describes volumetric mobile powder mixer (VMPM) systems and methods for VMPM operation and use. The VMPM is providing with a number of storage compartments (or bins) for liquid or solid ingredients including at least one powder storage bin, a powder transport system, a dust handling system, a solid/liquid mixing system, a cellular foam generator, a product delivery system, and a controller capable of monitoring the delivery and mixing of each of the ingredients, as well as the discharge of the final product. The controller determines if the proper mixture is being discharged by the VMPM and, if not, alerts the VMPM operator. In an automated embodiment, the VMPM controller is also configured to independently control the delivery and mixing of each of the ingredients, as well as the delivery of the final product.

A system and method for applying a construction material is provided. The method may include mixing blast furnace slag material, geopolymer material, alkali-based powder, and sand at a batching and mixing device to generate a non-Portland cement-based material. The method may also include transporting the non-Portland cement-based material from the mixing device, through a conduit to a nozzle and combining the transported non-Portland cement-based material with liquid at the nozzle to generate a partially liquefied non-Portland cement-based material. The method may further include pneumatically applying the partially liquefied non-Portland cement-based material to a surface.

A system and method for applying a construction material is provided. The system may include a batching and mixing device configured to mix blast furnace slag material, geopolymer material, alkali-based powder, and sand to generate a non-Portland cement-based material, the non-Portland cement-based material including 4% to 45% geopolymer material by weight; greater than 0% to 40% blast furnace slag material by weight, 10% to 45% alkali by weight, 20% to 90% sand by weight, less than 1% sulfate by weight, and/or no more than 5% calcium oxide by weight; a conduit configured to transport the non-Portland cement-based material from the batching and mixing device; and a nozzle configured to receive the non-Portland cement-based material and combine the transported non-Portland cement-based material with liquid to generate a partially liquefied non-Portland cement-based material, wherein the nozzle is further configured to pneumatically apply the partially liquefied non-Portland cement-based material to a surface.

A system and method for applying a construction material is provided. The method may include mixing one or more of 4%-45% volcanic rock by weight, greater than 0%-40% latent hydraulic material by weight, 10%-45% alkaline component by weight, and 20%-90% aggregate by weight to produce a dry binding agent mixture, using a dry mixer; and combining the dry binding agent mixture with water at a nozzle to produce a sprayable concrete compound.

Embodiments relate to a hydraulic fracturing system that includes a blender unit. The system includes an auger and hopper assembly to receive proppant from a proppant source and feed the proppant to the blender unit for mixing with a fluid. A first power source is used to power the blender unit in order to mix the proppant with the fluid and prepare a fracturing slurry. A second power source independently powers the auger and hopper assembly in order to align the hopper of the auger and hopper assembly with a proppant feed from the proppant source. Thus, the auger and hopper assembly can be stowed or deployed without use of the first power source, which is the main power supply to the blender unit.

A modular conveyor assembly employable with a materials mixing system is provided that includes an elongate frame supporting a motor driven axle, an idler axle, and a plurality of rollers supported in individual rotational fashion by the frame, and a belt and chain subassembly configured to be cycled rotationally about the axles and rollers, where the belt and chain subassembly includes first and second chains each attached along first and second sides of the belt, respectively, so that the belt and chains move in unison, and wherein the frame is configured to be detachable from a materials mixing system without the need to disassemble substantial components of the modular conveyor assembly.

An inorganic, non-Portland cement-based construction material is provided. The material may include blast furnace slag material, volcano rock flour, alkali-based powder, and sand. Other materials having various ratios may also be included.

A waterborne facility on a body of water includes a primary spoolable pipe and a pump. The end of the primary spoolable pipe may be guided from the waterborne facility to a location proximate to a selected site. The pump may be used to discharge a flowable material through the primary spoolable pipe. The waterborne facility may include a ready-mix concrete preparation system. However, the waterborne facility may deliver any flowable material to a selected site, which may be a land surface, underground, on a water surface, or underwater. Illustrative flowable materials include seawater, grout, cement, and sediment/mud.
