AAC Blocks FAQ’s

1. What are AAC Blocks ? 

Ans: AAC Blocks stands for Autoclaved Aerated Concrete, AAC Blocks are unique type of lightweight building materials because of its sound resistance, super heat and fire resistance.

2. What is the composition of AAC block ?

3. Are AAC blocks and light weight blocks the same ?

4. Are AAC blocks cheaper than bricks ?

Ans: Yes AAC blocks are cheaper than bricks, as it is greater in size and covers more area in lesser number of cubes whereas bricks are comparatively smaller than AAC blocks thus needs more number of cubes leading to increase in total construction cost.

5. Are AAC blocks stronger than bricks ?

Ans : Yes AAC blocks are stronger than bricks.

High Pressure steam- curing autoclaving process gives AAC blocks unmatchable strength to weight ratio, higher than even M 150 concrete, and far exceeds the Indian Building Code requirements. 

6. Are AAC blocks better than bricks 

Ans: Yes AAC blocks are better than brick in many terms such as AAC blocks are environmental friendly like AAC blocks consumes Fly Ash ( a waste product from thermal power plants) which is one of the most important raw material.

  • Red bricks are heavier in weight than AAC blocks with greater dry density.
  • AAC blocks provide thermal conductivity and sound insulation properties whereas red bricks doesn’t provide any of that.
  • AAC blocks are non toxic in nature, and also posses pest control qualities whereas red bricks doesn’t have any these characteristics.
  • AAC blocks are also cost effective.

7. Are AAC blocks durable than bricks ?

Ans: High Pressure steam- curing autoclaving process gives AAC blocks exceptional strength to weight ration, higher than even M 150 concrete, and far exceeds the Indian Building Code requirements. 

8. How are AAC blocks made ?

Ans: AAC Blocks are made in 4 Steps

Step 1 :- Raw Material Preparations like Fly Ash or Sand, limestone powder, Cement, Gypsum, Aluminium powder/paste etc.

Step 2 :- Dosing and Mixing.

Step 3 :- Casting, Rising and Pre-curing.

Step 4 :- Demoulding and Cutting.

12. What is the new material in constructing buildings ?

Ans : AAC Blocks is the new material in constructing building, Although AAC plants was set up in early 70’s in India but failed to make any great impact on Indian Industries, but in recent the usage and manufacturing process of AAC blocks is increased by huge margins because of its features and Eco-friendly nature.

13. Latest in building construction materials ?

14. What are the qualities of AAC blocks ?

Ans : Here are some qualities of AAC blocks

  1. AAC blocks is about 50% lighter than the other bricks or equivalent size.
  2. AAC blocks are Fire Resistant.
  3. AAC blocks are Earthquake Resistant.
  4. AAC blocks are Thermal Insulation.
  5. AAC blocks are Eco – Friendly.
  6. AAC blocks can also reduce up to 32% of energy consumption.
  7. AAC blocks are very easy to work with.
  8. Sound Insulation.

15. Why prefer AAC blocks ?

Ans : Well there are many advantages of AAC blocks over other building constructing materials. Here are some few of them which will definitely give your answer about why prefer AAC blocks over other ?

  1. AAC blocks are lightweight
  2. AAC blocks are Fire Resistant.
  3. AAC blocks are Earthquake Resistant.
  4. AAC blocks are Thermal Insulation.
  5. AAC blocks are Eco – Friendly.
  6. AAC blocks can also reduce up to 32% of energy consumption.
  7. AAC blocks are very easy to work with.
  8. Sound Insulation.
  9. Shorter Project duration and much more. 

16. How to increase age/life of a building ?

17. Best material to construct high-rises multi floor buildings ?

18. What is the best material to make walls ?

Ans : There are many materials available for making walls but AAC blocks are the best. Now to your question, Why AAC blocks is the best ?

AAC blocks offers ultimate workability, durability and flexibility. AAC blocks thermal performance is far superior than clay bricks in terms of sound resistance, fire resistance, draft resistance and many more.   

19. Can walls provide thermal insulation ?

Ans : Walls made using AAC blocks provide thermal insulation. As AAC blocks is made up by Fly Ash which is produced by Thermal Plants. AAC reduces air conditioning cost by up to 30%. So yes walls can provide thermal insulation.

20. What is the earthquake resistant material for building construction ?

Ans: AAC Blocks is used for making a building resistant.

Earthquake forces on structure are proportional to the weight of the building, hence lightweight blocks show excellent resistant to exclusively use AAC blocks. It has  been proven to withstand wind loads of category 5 tropical storms.

21. What are soundproof walls ?

Ans : Soundproof walls are those walls which provide noise cancellation and complete sound proof.

With its closed air pockets, AAC lightweight blocks can provide very good sound insulation/sound absorption with an STC( sound transmission class) rating of 44 . It can also be used as sound barrier wall along busy roads. ACC walls has an excellent sound transmission Class (STC) rating of 44. Result, Virtually sound proof inferiors.

22. Can water leakage in walls be prevented ?

23. How to stop water leakage in walls ?

Ans: Walls which are made using AAC blocks are water resistant

Microscopic structure of lightweight does not allow for capability action making it impervious to water. Its water barrier properties are further enhanced by adding silicone based additives.

24. Is there any waterproof building material ?

Ans: Yes AAC blocks is a waterproof building material.

Microscopic structure of lightweight does not allow for capability action making it impervious to water. Its water barrier properties are further enhanced by adding silicone based additives.

25. Can walls reduce electricity bills ? New technological innovation ?

26. How to make a green building (protect environment) ?

Ans: Nowadays AAC blocks are being widely used in making green buildings.

AAC is 100% green building material and is a walling of choice in LEED certified (ITC centre the highest rated green building has been using AAC)

AAc it is most energy and resource efficient in the sense that it uses least amount of energy and material per m3 of product. Unlike brick manufacturing process which use precious layer too-layer agricultural soil, AAC uses fly ash( 65% of its weight), thus provides the most constructive solution of the nation’s fly-ash utilization problem.

27. How to save energy while building home ?

Ans : By constructing building using AAC blocks you can save up to 32% of energy as compared to red bricks because of Thermal Insulation. It means it will not allow cold air during winter and warm air in summer .
