Brimax AAC Products LLP offers premium Autoclaved Aerated Concrete (AAC) blocks, engineered to transform modern construction. Manufactured with advanced German technology, our blocks deliver unmatched strength, durability, and eco-friendliness. Designed to meet the evolving needs of builders and developers, our AAC solutions set the standard for innovative and sustainable building materials.
AAC Blocks
AAC, a pioneering building material, has been transforming the construction industry since its inception in Europe in 1929. This lightweight, versatile material offers exceptional properties such as superior insulation, fire resistance, and load- bearing capacity. Its unique manufacturing process results in a porous structure that optimizes energy efficiency and acoustic performance. From residential homes to commercial complexes and industrial facilities, AAC is the preferred choice for builders and architects worldwide, thanks to its rapid construction timelines and sustainable benefits.

AAC blocks with higher thermal mass to retain heat and reduce energy consumption during colder months.
Frost Resistance:
Frost-resistant AAC blocks to withstand freezing temperatures and prevent damage.
(B) Aesthetically Pleasing AAC Solutions

Textured Finishes: Variety of textures, such as smooth, rough, or patterned finishes, to create visually appealing facades.

Coloured AAC Blocks: Coloured AAC blocks in a range of hues to match different architectural styles and preferences.

Custom Shapes and Sizes: Custom-shaped and sized AAC blocks to create unique architectural designs.

Integration with Other Materials: AAC blocks that can be seamlessly integrated with other building materials, such as wood, metal, and glass.
AAC Blocks Vs Clay Bricks
SR | Basis of Difference | AAC Blocks | Red Bricks |
---|---|---|---|
1 | Size Range | Wide standard size range and also customizable | Available in one or two standard sizes. Not Customizable |
2 | Construction speed | Bigger sizes, dimensional accuracy and fewer joints ensure higher construction speed | Smaller sizes, less dimensional accuracy and more number of joints reduce construction speed |
3 | The thickness of Mortar joints | Thin mortar joints in the range of 3-5 mm | Thick mortar joints of minimum 10 mm |
4 | Green Product | Made from non-toxic materials that are not harmful to the environment | Made from Natural Clay which destroys the most fertile top layer so |
5 | Seismic Resistant | Reduces the dead load of the building thereby increasing the safety against earthquakes. | Increases the dead load of the structure hence is more risky. |
6 | Fire Resistant | Fire Resistance of a 200 mm thick wall is up to 4 hours (As per PCA - Portland Cement Association | Fire Resistance of a 200 mm thick red brick wall is up to 2 hours. |
7 | Moisture Resistant | Less water absorption due to unconnected micropores | More water absorption |
8 | Thermal Conductivity | Thermal Conductivity is low leading to less heat transfer | Thermal Conductivity is high causing more heat transfer |
9 | Sound Absorption | Good sound insulation properties | No Sound Insulation properties |
10 | Dry Density | It varies between 451 - 1000 kg/m3 | It varies between 1600 - 1920 kg/m3 |
11 | Compressive Strength | High, between 3-4 N/mm2 | Lower compressive strength around 2.5 N/mm2 |
12 | Weight | Lighter in weight | Heavier |
13 | Termite Resistant | Possesses pest control qualities, Does not allow the spreading of termites | No pest control features |
14 | Curing Period | Less water required for curing | More water required for curing hence high electricity bills and labour costs |
15 | Wastage | Less wastage, almost 100% utilization is possible | More wastage due to average 10 to 15 % breakage during construction |
16 | Savings | More savings | Less savings due to higher costs |
