Detailed Description

In the present application, the coagulation during the contact can be made fast by continuing the rapid stirring of the heat-treated geopolymer with the activating liquid. Fly ash, a waste from flue gases and natural stone volcanic clay are one possible mixture or substitute for metakaolin. Researchers collected volcanic soil from efell's plateau, which was formed after volcanic eruption. After excavation, the volcanic soil is ground and can be used as it is. Another advantage is that it is rich in base. This can reduce the concentration of the alkaline activating solution, thereby reducing the cost. Mixing collagen-made bones with eggshells results in a "lattice-type structure" that is stronger than a simple artificial bone or eggshell. The first geopolymer is metakaolin, a heat-treated kaolin, as the raw material. When heated to 600 degrees celsius, kaolin changes structure, becomes more reactive, and coagulates very quickly when in contact with the activating solution.

Because kaolin does not release carbon dioxide during heating and has a much lower light-off temperature than when cement is fired, it has a much lower carbon footprint.

The invention discloses concrete which comprises the following raw materials: geopolymer, activating liquid, artificial bone, eggshell, sea sand, silicon powder, graphene powder, fly ash, concrete reinforcing agent and water; the geopolymer is prepared by the following method: selecting metakaolin as a raw material, heating the metakaolin to 500-600 ℃ in a closed container, and naturally cooling the metakaolin; and grinding the cooled metakaolin into powder, and taking heat treatment products with the particle sizes of 0.3-3 mm and 5-8 mm.
