Autoclaved aerated fly ash brick uses fly ash as the main raw material, which is mixed with stone chips and aggregate mixture before going through preparation, compression molding, and high-pressure maintenance.
| Comparison with Clay Sntered Bricks | ||
| Performance Comparison | Fly Ash Brick | Clay Sintered Brick |
| Weight | Light, about 2.5kg/block | Heavy, about 3.5kg/block |
| Thermal Insulation | Good, low thermal conductivity, 3-4 times higher thermal insulation performance than clay bricks | Average, medium thermal conductivity, average thermal insulation performance |
| Sound Insulation and Noise Reduction | Good, with a large number of pores inside the product, which has the double function of sound absorption and sound insulation | Average, a small number of pores inside the product, sound insulation effect is not good |
| Price | Cheap, 0.3-0.5 yuan/block | Expensive, 0.8-1.2 yuan/block |
1. High strength and anti-seismic: With a seismic capacity 2 grade higher than ordinary clay bricks.
2. Thermal insulation and heat resistance: The coefficient of thermal conductivity is 1/6 of ordinary concrete, and the heat resistance reaches the first-class fireproof standard.
3. Freeze resistance, water resistance, acid and alkali resistance: Without losing strength after 15 freezing and thawing cycles.
4. Fast construction and low cost: Continuous masonry, flexible construction, easy to manage.
5. Porous sound insulation: Sound insulation performance: sound insulation of 120㎜ thick wall is 46dB, sound insulation of 180㎜ thick wall is 53dB, sound insulation of 240㎜ thick wall is 58dB.
1. Alternative for solid clay bricks, suitable for the load-bearing carrier of multi-story brick structures.
2. Used in antique garden construction projects.
3. Used for hotel and Chinese-style interior decoration.
