Abstract

The invention discloses an unfired hollow brick which is prepared from the following raw materials in parts by weight: 40-50 parts of phosphogypsum, 20-30 parts of fly ash, 1-5 parts of quicklime, 40-50 parts of sludge generated by sewage treatment plants, 5-8 parts of tile residue, 12-15 parts of Portland cement clinker, 5-8 parts of calcite powder, 4-6 parts of antimonial dross, 8-10 parts of self-made concrete, 2-3 parts of glycerol, 0.1-0.2 part of cetyl trimethylammonium bromide, 1-2 parts of sodium acetate, 2-5 parts of sodium thiosulfate, 1-2 parts of fatty alcohol polyethenoxy ether sodium sulfate, 0.2-0.4 part of amine azodicarbonate, 0.3-0.5 part of carboxymethyl cellulose and a proper amount of water. The hollow brick has the characteristics of high strength, favorable freezing resistance and the like, can insulate heat and sound and resist moisture, can recycle industrial tailings, does not need sintering, saves the energy, utilizes the residues and wastes, can substitute for the solid clay brick with the defects of high energy consumption, field destroying and severe pollution, and can be used in various construction projects.

Description

technical field [0001] The invention relates to the field of new building materials, in particular to an unfired 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 object of the present invention is to provide a non-fired hollow brick and its preparation method. The ...
