Abstract

The invention discloses a lightweight energy-saving brick and a preparation method thereof, and relates to the field of building materials. The lightweight energy-saving brick is characterized by comprising by weight: 20-35 parts of Tai lake sludge, 10-20 parts of city sludge, 1-5 parts of a dry-mixing agent, 10-15 parts of a lightweight filler, 5-10 parts of straw-coated particles, 5-10 parts of attapulgite clay, 8-15 parts of zeolite, 5-10 parts of fly ash, 3-5 parts of coconut shell charcoal, 3-5 parts of ceramsite, 3-5 parts of modified sepiolite, 1-2 parts of thickening powder, 5-10 parts of a cementing material, 0.1-0.3 part of a deodorizing aid, and 8-10 parts of water. According to the present invention, the produced lightweight energy-saving brick has advantages of light weight, thermal insulation, water resistance, shock resistance and durability while the production cost is low and the method is easy to popularize, and the preparation method has characteristics of city sludge discharge reduction, good social benefits, and good economic benefits.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a lightweight energy-saving brick and a preparation method thereof. Background technique [0002] After clay bricks are disabled, although there are light-weight aerated cement blocks with better thermal insulation properties as wall materials, the investment is large and it is not easy to popularize, especially the material is loose and the slurry is easy to fall off. Low and poor security, the current porous cement bricks are only made of cement and sand or slag mixed with crushed materials, whether it is sand and gravel bricks, fly ash bricks or metal slag powder bricks and coal gangue bricks, there is no lightweight Insulation materials are blended and produced, not only the bricks are too heavy, but also permeable to water and heat, easy to delaminate and damaged, not durable, high cost, and long construction period. [0003] Among them, aerated cement bricks are mainly ma...
