Heat-resistant and corrosion-resistant lightweight foam concrete and preparation method thereof

The invention discloses heat-resistant and corrosion-resistant lightweight foam concrete and a preparation method thereof, and belongs to the technical field of building materials. The lightweight foam concrete is prepared from the following raw materials in parts by weight: 40-70 parts of a gel material, 20-40 parts of fly ash, 10-20 parts of fine sand, 10-20 parts of inorganic powder, 6-15 parts of modified glass fibers, 3-10 parts of a foaming agent, 0.01-0.05 part of a foam stabilizer and 0.1-2 parts of an additive. The raw materials for preparing the foam concrete are scientifically proportioned and selected, the two-step modified glass fibers are doped to help stable formation and uniform distribution of the microporous foam, the heat resistance and corrosion resistance of the foam concrete are greatly improved, the operation method is simple and convenient, no pollutant is generated, and the method is suitable for industrial production. The application field of the foam concrete can be greatly expanded
