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 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.
1. A system for applying a construction material comprising:
a 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, the non-Portland cement-based material including one or more of:
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
no more than 5% calcium oxide by weight;
a delivery mechanism operatively connected with the batching and mixing device configured to transport the non-Portland cement-based material from the batching and mixing device to a portable container; and
a nozzle configured to receive the non-Portland cement-based material from the portable container via a hose, wherein the nozzle is configured to 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 blast furnace slag includes one or more of fly ash, kaolin, trass, and granulated slag.
3. The system of claim 1 , wherein the alkali includes one or more of sodium silicate, alkali hydroxide, and alkali carbonate.
