What are Autoclaved Aerated 
Concrete (AAC) Blocks?
Presentation by Indian Trade Street 
 AAC contains Aluminium powder. Aluminium powder is 
used at a rate of 0.05%–0.08% depending on volume 
and density.
 While mixing concrete material, water reacts with dry 
aluminium powder and produces hydrogen gas. This 
gas cause bubbles .
 They remain fixed in the place as the AAC dries, this 
results in the lightweight AAC blocks.
  In some countries, like India and China, fly ash 
generated from coal fire plants having silica content is 
used as an aggregate.

Advantages of using 
       AAC Blocks.

 1. Fire Resistant
Use of AAC blocks eliminates the cost of additional fireproofing material. It 
does not emit toxic gases when exposed to the fire.
AAC withstand the fire and earthquakes and the chances of losses and 
damages are less when compared to other material used in construction.
 
 2. High Thermal Efficiency
AAC is considered as sustainable construction material because of its 
excellent insulating quality. 
Solid wall construction of AAC structure creates airtight building envelope 
and maintains indoor temperature over 24 hours.
 
 3. Moisture and Mortar
The drying Shrinkage i.e. Moisture movement of the mortar is avoided in the 
AAC masonry construction.
 AAC ensures even distribution of mortar and saves energy, water and 
labour.

 4. Use of AAC blocks is very economic.
The production cost of AAC blocks is less than other materials; also the bigger 
size of AAC blocks saves time and labour. 
Due to the thermal efficiency of AAC blocks the cost of energy is low. Also 
maintenance cost is negligible and loss during the construction is less 
compared to normal red bricks.
 
 5. Eco friendly green material
In the manufacturing clay bricks the quality soil is depleted and natural 
resources are eroded. It results in major soil erosion and ecological imbalance.
But in the production of AAC block, AAC manufacturing plants uses fly ash 
which is waste material generated by thermal power stations.
Use of industrial waste material in productive way is beneficial and on the other 
hand natural resources will be saved in every sense.
AAC blocks or bricks are truly green material.

 6. Improves Indoor Air Quality and reduces noise pollution.
The additional quality of AAC is it can reduce and absorb noise and 
maintain indoor air quality.
Millions of independent air cells in an AAC blocks reduces sound 
transmission. AAC blocks have excellent sound insulation and 
absorption qualities.
 7. Structural strength
The contraction capacity of AAC blocks is very good, they are lighter 
than normal bricks. 
It is easy and cheap to transport them. It reduces overall dead load on 
the building, therefore extremely useful for tall buildings.
