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.

A compression device, means for controlling the compression device, a drum having an inner chamber, means for rotating the drum, and first and second delivery devices for delivering first and second materials into the inner chamber of the drum while the drum is rotating. The compression device compresses the first and second material in the inner chamber of the drum while the drum is rotating about the center of the drum in response to the means for controlling the compression device. The apparatus may include a stirring device; and a means for controlling the stirring device; wherein the stirring device is configured with respect to the drum so that the stirring device can be moved up and down to a desired depth within the drum and rotates within the inner chamber of the drum to stir the first and second materials in the drum while the drum is rotating.

A constrictor valve can be associated with a conduit in fluid communication with a mixer to control a flow of cementitious slurry discharged from the mixer through the conduit. The constrictor valve can include a constrictor housing, a webbing constriction assembly, and a drive mechanism. The webbing constriction assembly includes a pair of rotatable members rotatably mounted to the constrictor housing and a plurality of webbing straps connected to the rotatable members and wrapped around the conduit. The drive mechanism includes a drive shaft and a gear assembly configured to rotate the rotatable members in opposing winding directions in response to the drive shaft rotating in a tighten direction to wrap the webbing straps tighter around the conduit to compress it and to rotate in opposing unwinding directions in response to the drive shaft rotating in a loosen direction to loosen the grip of the webbing straps on the conduit.
