Coal gangue shale sintered hollow brick with reasonable proportioning and preparation method of brick
The invention discloses a coal gangue shale sintered hollow brick with reasonable proportioning. The coal gangue shale sintered hollow brick is characterized by comprising the following raw materials in parts by weight: 60-63 parts of processed coal gangue shale mixed powder, 50-55 parts of coal ash, 1-2 parts of sodium silicate, 10-13 parts of municipal sludge, 1-2 parts of clarified limewash, 2-3 parts of ammonium molybdate and 9-10 parts of water. According to the coal gangue shale sintered hollow brick, the coal gangue and the shale are subjected to preprocessing and are mixed with other components, so that the plasticity index is improved, a blank body is relatively compact, the cracking phenomenon during drying is improved, and the durability of the brick body is improved; because the coal ash which is subjected to mixed grinding together with sodium silicate, the granularity is small and the strength is increased; the municipal sludge mixed with the clarified limewash is added, so that the hollow brick is safe and sterile, and the compactness is improved. The coal gangue shale sintered hollow brick is high in smoothness and flatness, high in energy conservation, high in environmental-friendly property, reasonable in proportioning of the components, high in strength and high in quality.
