Quartz tailings heat-insulating building block and preparation method thereof
The invention relates to the technical field of quartz tailings applied to building materials and especially relates to a quartz tailings heat-insulating building block and a preparation method thereof. The heat-insulating building block is prepared by combining a hollow block with a filling material; the raw materials of the hollow block and the filling material both comprise quartz tailings powder; the quartz tailings powder is formed by grinding the quartz tailings into fine powder, wherein the fineness is subjected to the screening treatment by adopting a square hole sieve with the size of aperture being 45mu m and the weight of screen residue is 10%; the content of silicon dioxide in the quartz tailings is 70%; the limitation of the raw material ingredients in the hollow block and the filling material is adopted, so that all the raw materials are interacted, especially, the synergic effect between the quartz tailings and the quick lime, the aluminum powder or cement is achieved; the content of the radioactive substance in the raw materials is reduced, so that the radioactivity is reduced and the quality of the heat-insulating building block is increased.
