System and method for making and applying a non-Portland cement-based material
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.
1. A system for applying a construction material comprising:
a batching and mixing device associated with a mobile batching and mixing vehicle, the batching and mixing device configured to mix blast furnace slag material, geopolymer material including non-pumice-based volcano rock flour, alkali-based powder, and sand to generate a non-Portland cement-based material, wherein the components of the non-Portland cement-based material have a Blaine fineness value of approximately 2500-5000 cm 2 /g;
a delivery mechanism affixed to the batching and mixing device configured to transport the non-Portland cement-based material from the batching and mixing device to a portable container associated with a portable gun; and
a hose configured to transport the non-Portland cement-based material from the portable container to a handheld nozzle, wherein the handheld nozzle is 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.
2. The system of claim 1 , wherein the alkali-based powder includes silicate.
3. The system of claim 1 , wherein batching and mixing is performed as at least one of a dry-mix and a wet-mix.
4. The system of claim 1 , wherein the non-Portland cement-based material is inorganic.
5. The system of claim 1 , wherein the non-Portland cement-based material includes at least one of clay, gneiss, granite, liparite, andesite, picrite, potassic feldspar, albite, pumice and zeolite.
