Abstract

The invention belongs to the technical field of building materials and particularly relates to a filling material based on ceramic tile polishing mud and building waste and a preparation method of the filling material. The filling material comprises a cementing material, a thickening time control agent and water, wherein the cementing material is prepared from modified ceramic tile polishing mud, modified building waste micro powder and cement; and the modified building waste micro powder is prepared from building waste and an activator. The filling material provided by the invention is high in utilization ratio of waste, realizes resource utilization of ceramic tile polishing mud and building waste, has high working performance, high mechanical properties, excellent durability and simple production and construction processes, and can be widely used for filling of coal mines, mines and the like.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a ceramic brick polishing mud construction waste-based filling material and a preparation method thereof. Background technique [0002] During the grinding and polishing process of polished tiles, a large amount of polishing waste will be produced. This kind of polishing waste has a fine particle size and is dispersed after air drying. It is easy to fall everywhere with the wind, which will seriously threaten the health of the surrounding people and cause The compaction of the surrounding land leads to serious environmental pollution. According to statistics: the output of my country's ceramic polished tiles has reached 2.5 billion m 2 , in the grinding and polishing process of ceramic polished tiles, the surface layer of 0.5-0.7 mm will usually be removed from the surface of the brick, sometimes even up to 1-2 mm, then the production of 1m 2 Polishing ti...
