Autoclaved aerated concrete block is a porous silicate material made of cement, fly ash, lime, and other raw materials, with aluminum powder (paste) as the aerating agent, through grinding, casting, aerating, pre-maintenance, cutting, autoclaving, and maintenance, and made into a high-quality building product through a proprietary formula and a unique high-temperature and high-pressure process.

Light weight and high strength, precise size, high quality, and low price supporting binder
1. Thermal insulation: Thermal conductivity 0.11w/(m-k), thermal insulation performance is 3-4 times that of clay bricks.
2. Fire-resistant and flame retardant: Combustion grade A1, fire-resistant limit up to 3h, fire-resistant performance is 6-8 times that of concrete.
3. Sound insulation and noise reduction: There are a large number of pores inside the product, which has the double function of sound absorption and sound insulation, and the sound insulation index of 100mm thick blocks (double-sided putty) reaches 40-50 decibels.
4. Green and environmentally friendly: Raw materials are selected from the best, certified green building materials products, low-carbon and environmentally friendly.
5. Waterproof and anti-seepage: Uniform distribution of 1-2mm diameter closed holes on the inside to effectively prevent the spread of water, with impermeability 85% higher than clay brick wall.
6. Good processability: Complete specifications and customizable, simple construction, quick installation, can be planed, sawed, and drilled for convenient operation.
Frame and steel structures for residential, public, and factory buildings, etc. It can be used as an interior wall, exterior wall, fireproof insulation wall.
