The invention discloses a purple sand shale hollow brick which is composed of the following raw materials in parts by weight: 15-25 parts of purple sand shale, 40-50 parts of coal gangue, 30-35 parts of iron-ore slag, 8-15 parts of water, 5-6 parts of quicklime and 0.2-1 part of a binder. The hollow brick obtained through crushing, sealing and ageing, blanking, drying and sintering is strong in water absorptivity and has fire resistance and thermal insulation effect. The purple sand shale hollow brick is high in compressive strength and excellent in comprehensive performance and is in line with national standards. The purple sand shale hollow brick is wear resistant and shock resistant and can be carried directly, and the rate of finished products is high. By utilizing the purple sand shale hollow brick, energy is saved, emission is reduced, environmental pollution is prevented, and ecological environment is protected. The production process is simple, the preparation is convenient, the production period is short, waste materials are used, resources are saved, the production cost is low, and the purple sand shale hollow brick is beneficial to mass industrial production.
