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. ## Claims ### Claim 1 A binding agent mixture comprising: 4% to 45% non-pumice volcanic rock flour by weight; greater than 0% to 40% a latent hydraulic material by weight, wherein the latent hydraulic material includes one or more of lignite fly ash, anthracite fly ash, kaolin, and trass and wherein the volcanic rock has a Blaine value greater than 3,000 and the latent hydraulic material has a Blaine value greater than 3,000; 10% to 45% an alkaline component by weight, wherein the alkaline component includes one or more of alkali hydroxide, and alkali carbonate; 20% to 90% an aggregate by weight; less than 1% sulfate by weight, wherein the sulfate in the binding agent mixture is in the form of contaminants; and no more than 5% calcium by weight. ### Claim 2 (depends on 1) The binding agent mixture of claim 1, wherein the sulfate in the binding agent mixture is less than 0.5% by weight. ### Claim 3 (depends on 1) The binding agent mixture of claim 1, wherein the calcium in the binding agent mixture is in the form of calcium oxide. ### Claim 4 (depends on 1) The binding agent mixture of claim 1, wherein the calcium in the binding agent mixture is no more than 2% by weight. ### Claim 5 (depends on 1) The binding agent mixture of claim 1, wherein the volcanic rock is pozzolan. ### Claim 6 (depends on 1) The binding agent mixture of claim 1, wherein the aggregate includes one or more of gravel, sand, basalt, perlite, and expanded shale. ### Claim 7 (depends on 1) The binding agent mixture of claim 1, wherein the aggregate in the binding agent mixture is 20% to 70% by weight. ### Claim 8 (depends on 1) The binding agent mixture of claim 1, wherein the aggregate in the binding agent mixture is 20% to 50% by weight. ### Claim 9 (depends on 1) The binding agent mixture of claim 1, wherein the aggregate in the binding agent mixture is 20% to 40% by weight. ### Claim 10 (depends on 1) The binding agent mixture of claim 1, further comprising water. ### Claim 11 A binding agent mixture comprising: 4% to 45% non-pumice volcanic rock flour by weight; greater than 0% to 40% a latent hydraulic material by weight, wherein the latent hydraulic material includes one or more of lignite fly ash, anthracite fly ash, kaolin, and trass and wherein the volcanic rock has a Blaine value greater than 3,000 and the latent hydraulic material has a Blaine value greater than 3,000; 10% to 45% an alkaline component by weight, wherein the alkaline component includes one or more of powdered sodium silicate and a spray-dried silicate and wherein the alkaline component includes alkali hydroxide and alkali carbonate; 20% to 90% an aggregate by weight; less than 1% sulfate by weight, wherein the sulfate in the binding agent mixture is in the form of contaminants; and no more than 5% calcium by weight.
