The invention discloses a carbide slag and weathered quartzite autoclaved aerated concrete block and a production method of the carbide slag and weathered quartzite autoclaved aerated concrete block,and belongs to the field of novel wall body materials for buildings. The carbide slag and weathered quartzite autoclaved aerated concrete block is prepared from the following raw materials in percentby weight: 60%-70% of weathered quartzite, 15%-25% of carbide slag, 10%-20% of quick lime, 8%-10% of cement, 1%-2% of gypsum, 1.35%-1.50% of glass beads, 0.01%-0.05% of alkali-resistant glass fiber, 0.070%-0.075% of aluminum paste, 0.01%-0.02% of a surfactant, and the balance of water. The obtained autoclaved aerated concrete block is low in density, high in strength, and excellent in durability and thermal insulation property. The tailings and the industrial waste are used, the energy consumption is reduced in the production process, the energy is saved, environment pollution is reduced, theweight of the structure of the carbide slag and weathered quartzite autoclaved aerated concrete block is low, the height of the carbide slag and weathered quartzite autoclaved aerated concrete blockslaid at one time is not restricted in the construction process, the construction efficiency is improved, and the carbide slag and weathered quartzite autoclaved aerated concrete block is a novel wallbody material having a bright development prospect.
