Aerated Concrete

Aerated concrete is made from siliceous materials (sand, fly ash) and calcareous materials (lime, cement), and aluminum powder is also added to serve as a foaming agent. We can provide a complete production line for this product, encompassing batching, mixing, pouring, pre-curing, cutting, autoclaving, and curing.

Aerated concrete has a uniformly distributed network of fine pores. It has a density of 500-900 kg/m³, a fire resistance temperature of 650℃, a sound insulation performance of 41 dB (based on a 10mm thick wall), and a thermal conductivity of 0.11-0.16 W/mK.

When processing this material, you can choose to produce blocks or panels, and whether it is a non-load-bearing or load-bearing structure when it is actually put into use. If it is to be used as a load-bearing floor slab, it needs to be reinforced with steel bars.

The advantages of aerated concrete are as follows:

1. Lightweight: With a porosity of 70%~85%, its bulk density is generally 500~900 kg/m³, which is 1/5 of ordinary concrete, 1/4 of clay bricks, and 1/3 of hollow bricks, similar to wood, and it can float on water. This reduces the building's self-weight and significantly lowers the overall construction cost.

2. Fireproof: Most of the main raw materials are inorganic, thus possessing excellent fire resistance and not emitting harmful gases when exposed to fire. It is fire-resistant up to 650 degrees Celsius, classifying it as a Class A fire-resistant material. A 90mm thick wall has a fire resistance of 245 minutes, and a 300mm thick wall has a fire resistance of 520 minutes.

3. Sound Insulation: Due to its unique porous structure, it has a certain sound absorption capacity. A 10mm thick wall can achieve 41 decibels.

4. Thermal Insulation: Because the material has a large number of pores and micropores, it has excellent thermal insulation properties. The thermal conductivity is 0.11-0.16 W/MK, which is 1/4 to 1/5 that of clay bricks. Typically, the thermal insulation effect of a 20cm thick aerated concrete wall is equivalent to that of a 49cm thick ordinary solid clay brick wall.

5. Environmentally friendly: The manufacturing, transportation, and use processes are pollution-free, protecting arable land and saving energy, making it a green and environmentally friendly building material.

6. Durable: The material has stable strength. After one year of atmospheric exposure, the strength increased by 25%, and remained stable even after ten years.

7. Quick to process: It has good workability; it can be sawed, planed, drilled, and nailed, and can be bonded with suitable adhesives, creating favorable conditions for construction.
