Environment-friendly high-parameter tailings non-fired and non-steamed brick
The invention belongs to the technical field of building materials, and particularly relates to an environment-friendly high-parameter tailings non-fired and non-steamed brick. The environment-friendly high-parameter tailings non-fired and non-steamed brick is characterized by comprising the following raw materials in percentage by weight: 2%-6% of a harmless treating agent, 5%-10% of concrete, 80%-85% of tailings sand and 5%-8% of water. The environment-friendly high-parameter tailings non-fired and non-steamed brick is prepared by screening, stirring, ageing, restirring, dry-pressing molding, and natural curing according to the processes; the harmless treating agent is a composite agent prepared from magnesium oxide with the fineness of 200 meshes, quick lime, gypsum powder and calcium nitrate; and PO42.5# concrete is adopted as cement. The phenomena such as swelling and upheaval of a wall surface or falling of a wall surface plaster layer are avoided after the environment-friendly high-parameter tailings non-fired and non-steamed brick is used for a long period of time; the compressive strength is greatly improved; the problem of white crystal separated out from the brick body surface is completely eradicated through advanced innocent treatment on tailings; the consumption of a single brick body on the tailings is improved; and the environment-friendly high-parameter tailings non-fired and non-steamed brick is environment-friendly.
