Abstract

The invention discloses a lithium slag cored brick. The brick is made by using the following raw materials, by weight, 20-30 parts of fly ash, 20-25 parts of lithium slag, 10-15 parts of coal slag, 15-17 parts of lime, 2-4 parts of gypsum, 10-15 parts of light calcium powder, 10-15 parts of self made concrete, 4-6 parts of attapulgite, 2-3 parts of cement clinker, 8-10 parts of an aluminum phosphate solution with the concentration of 4-5%, 1-2 parts of alumina, 1-2 parts of nanometer carbon powder, 5-8 parts of a quartz fiber, 0.2-0.5 parts of glycerol and 18-20 parts of water. The hollow brick made in the invention has the advantages of light weight, high strength, clay saving, fuel saving, improvement of the heat and sound insulation performances of the brick, realization of recycling of the lithium slag, reduction of the pollution to environment, and changing of wastes into valuables.

Description

technical field [0001] The invention relates to the field of new building materials, in particular to a lithium slag hollow brick and a preparation method thereof. Background technique [0002] Traditional hollow bricks are made of clay, shale, etc. as the main raw materials, after raw material processing, molding, and sintering. They are light in weight, high in strength, and have good thermal insulation and noise reduction performance. [0003] With the development of the construction industry, the demand for hollow bricks is increasing day by day. The waste of manufacturing traditional hollow bricks will waste a lot of resources such as clay, which is costly and pollutes the environment during firing. Researching new raw materials and new techniques of hollow bricks has become the development direction of hollow brick manufacturers. Contents of the invention [0004] The purpose of the present invention is to provide a lithium slag hollow brick and its preparation meth...
