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 method for applying a construction material comprising:
mixing blast furnace slag material, geopolymer material including non-pumice-based volcano rock flour, alkali, and sand at a batching and mixing device to generate a non-Portland cement-based material;
transporting the non-Portland cement-based material from the batching and mixing device, through a conduit to a nozzle;
combining the transported non-Portland cement-based material with liquid at the nozzle to generate a partially liquefied non-Portland cement-based material; and
pneumatically applying the partially liquefied non-Portland cement-based material to a surface.
2. The method of claim 1 , wherein the non-Portland cement-based material includes 4% to 45% geopolymer material by weight.
3. The method of claim 2 , wherein the non-Portland cement-based material includes greater than 0% to 40% blast furnace slag material by weight.
4. The method of claim 3 , wherein the non-Portland cement-based material includes 10% to 45% alkali by weight.
5. The method of claim 4 , wherein the non-Portland cement-based material includes 20% to 90% sand by weight.
6. The method of claim 5 , wherein the non-Portland cement-based material includes less than 1% sulfate by weight.
7. The method of claim 6 , wherein the non-Portland cement-based material includes no more than 5% calcium oxide by weight.
8. The method of claim 1 , wherein the blast furnace slag includes one or more of fly ash, kaolin, trass, and granulated slag.
9. The method of claim 1 , wherein the alkali includes one or more of sodium silicate, alkali hydroxide, and alkali carbonate.
