What are aerated blocks used for? | UK Construction Blog

 · Density. Aerated blocks have a low density, which ranges between 25-50lb. The lighter aerated concrete blocks are used for insulation purposes but have indifferent strength. Nevertheless, the heavier grade of aac blocks has higher straight with low insulation value. The density range for the heavier grade ranges from 40 to 50 lb. per cubic feet.

What are the benefits of Autoclaved Aerated Concrete Blocks?

Autoclaved Aerated Concrete Blocks have excellent sound absorption quality due to their porous structure, allowing sound attenuation of about 42dB blocking sound and disturbance from outside. That''s why it is ideal for constructing hospitals, schools, hotels, and other structures that require acoustic insulation.
