Environmental-friendly aerated brick containing needlebush pulp
The invention discloses an environmental-friendly aerated brick containing needlebush pulp. The environmental-friendly aerated brick containing needlebush pulp is prepared from the following raw materials in parts by weight: 2-4 parts of polystyrene fiber, 1-3 parts of polyvinyl alcohol, 13-15 parts of calcium carbonate, 2-3 parts of needlebush pulp, 2-3 parts of animal bone ash, 1-3 parts of 20-30% hydrogen peroxide, 3-5 parts of iron ore milltailings, 1-1.5 parts of quick lime, 1.8-3 parts of sodium chloride, 1-3 parts of calcium lignosulphonate, 23-35 parts of modified waste concrete, 10-15 parts of cement, 3-5 parts of gypsum and a proper amount of water. By virtue of hygroscopicity and good dispersibility of the needlebush pulp, the toughness of the concrete is improved. By applying industrial waste carbide slag to produce a wall body material, the strength and toughness of the brick are improved, and the double effects of governing environmental pollution and comprehensively and efficiently using wastes are achieved.
