The AAC Blocks are 2.5 times lighter Block compared to conventional Bricks, while providing the similar strengths. The specific gravity stays around 0.6 to 0.65. This is one single most USP of the AAC blocks, because by using these blocks in structural buildings, the builder saves around 30 to 35 % of structural steel, and concrete, as these blocks reduce the dead load on the building significantly.
Made from natural and recyclable materials, AAC production is not harmful t o the environment , neither in process nor in finished product.
Autoclaved Aerated Concrete products are not affected by harsh clima tic conditions and will not degrade under normal atmospheric conditions.
Flexible portfolio density from 325kg/ m3 to 725kg/ m3 • To be produced in easily handled sizes .
Autoclaved Aerated Concrete product has excellent thermal insulation and fireproof performance due to its low bulk density comprised of many independent , tiny and dispersed air holes. Such unique structure enables ACC product to prevent water and air penetrating through it effectively .
Autoclaved Aerated Concrete is totally inorganic and incombustible. The product is especially suited for fire rated applications .
The accurate manufacturing process ensures that Autoclaved Aerated Concrete panels and blocks are always produced to size as they leave the facto ry. This results in less on-site trimming and reduced quantities of mortar and finishing materials use.
One AAC Block is Equivalent to approximately 9 Standard Clay Bricks yet less than 1/4th the weight , leading to laying. Installation of AAC is 2.5 times faster than bricks.
| Parameter | AAC Block | Clay Bricks |
|---|---|---|
| Structural Cost | Steel Saving Upto 15% | No Saving |
| Cement Mortar for Plaster & Masonry | Requires less due to flat, even surfaces & less number of joints | Requires more due to irregular surface and more number of joints. |
| Breakage | Less than 5% | Average 10 to 12 % |
| Construction speed | Speedy construction due to its big size, light weight & ease to cut in any size or shape | Comparatively slow |
| Quality | Uniform & Consistent | Normally varies |
| Fitting & Chasing | All kind of fitting and chasing possible | All kind of fitting and chasing possible |
| Carpet Area | More due to less thickness of walling material | Comparatively low |
| Availability | Anytime | Shortage in monsoon |
| Energy Saving | Approx. 30% reduction in air-conditioned load | No such saving |
| Chemical Composition | Sand/Flyash used around 60 - 70 % which reacts with Lime & Cement to form AAC | Soil is used which contains many inorganic impurities like sulphates etc. resulting in efflorescence |
