Vitrified tile prepared from riverbed sludge as principal raw material and preparation method of vitrified tile
The invention belongs to the technical field of environmental engineering and construction materials, and particularly relates to a vitrified tile prepared from riverbed sludge as a principal raw material and a preparation method of the vitrified tile. The vitrified tile comprises the following components in percentage by weight: 60-80% of riverbed sludge dry basis, 10-20% of albite, and 10-20% of potassium feldspar. The preparation method comprises the following steps: pretreating the riverbed sludge, performing wet method ball milling and drying, pelletizing, preparing green bodies of the vitrified tiles, and sintering at high temperature. The scheme by using the riverbed sludge as the principal raw material to prepare the vitrified tile, provided by the invention, utilizes the solid waste building material of the riverbed sludge, provides a feasible approach to treat the riverbed sludge, avoids the conventional landfill manner, saves land resources, effectively reduces the environmental pollution of the riverbed sludge, and achieves the excellent economic benefit, social benefit and environmental benefit; meanwhile, the riverbed sludge is used for preparing the vitrified tile, so that the production cost is reduced, and the development of the building material industry can be promoted.
