Environment-friendly high-volume tailing unfired non-steamed brick and manufacturing method thereof
The invention belongs to the technical field of building materials and particularly relates to an environment-friendly high-volume tailing unfired non-steamed brick and a manufacturing method thereof. Raw materials comprise a harmless treatment agent, cement, tailing sand and water. The raw material are screened, mixed, aged and mixed again and undergo dry pressing forming and natural curing to manufacture the environment-friendly high-volume tailing unfired non-steamed brick according to a process. The harmless treatment agent is a composite material made of magnesium chloride, quicklime, gypsum powder, calcium chloride, aluminum sulphate, silicate and silica fume and the like with the fineness of 400 meshes, and the cement is of a PO42.5 type. The environment-friendly high-volume tailing unfired non-steamed brick is characterized by comprising, by weight percentage, 2-6% of harmless treatment agent, 5-10% of cement, 80-85% of tailing sand and 5-8% of water. After long-term use, the environment-friendly high-volume tailing unfired non-steamed brick avoids wall bulging or dropping of a wall painting layer; the compressive strength of the environment-friendly high-volume tailing unfired non-steamed brick is also greatly improved; the problem that white crystal substances are separated out of the surface of a brick body is solved through the deep harmless treatment of tailings; and the consumption of the tailings through single brick bodies is improved, and the environment-friendly high-volume tailing unfired non-steamed brick is environmentally friendly.
