AAC was perfectedin the mid-
1920s by the Swedish architect
and inventor Dr. Johan Axel
Eriksson, working with Professor
Henrik Kreüger at the Royal
Institute of Technology. The
process was patented in 1924.
4.
The AAC blockmanufacturing process
involves the following steps:
1. Raw material preparation. The key ingredient to
manufacture AAC blocks is fly ash or pond ash.
...
2. Dosing and mixing. ...
3. Casting, Rinsing and Pre-curing. ...
4. Demoulding and cutting. ...
5. Entering autoclave. ...
6. Packing and loading.
5.
1. Fire resistance4-6 hours, depending on the
size.
2. Sound reduction 60 dB.
3. Thermal conductivity 0.25 w/Km.
4. Energy efficiency Up to 25% reduction in air-
conditioning costs.
5. Thermal efficiency3X higher than traditional
bricks.
6.
AAC block pricesrange anywhere from INR
2,000 to INR 4,000 per cubic meter,
depending on the manufacturer you buy it
from. As expected, the cubic meter price will
vary depending on how many pieces you
buy.
7.
AAC BLOCKS Redbricks
1. AAC blocks are lightweight (up to 3 times more
lightweight than traditional red bricks) and are easy to
handle.
Red bricks come in different
weights depending on the
seller.
2. Each of the AAC blocks can weigh anywhere from 3
kg to 15 kg, depending on the size of the individual
blocks.
The average weight can
range between 2-3.5 kg for
one block.
3. AAC blocks are very large in size. Red bricks are smaller in
size.
4. AAC blocks are usually uniform in size and don’t
come with rugged or rough edges that need to be
trimmed.
The size and shape of red
bricks can be slightly
different as they are mostly
handmade. They also have
rough edges that need
trimming before use.
5. AAC blocks are mostly used for non-load bearing
purposes and used to create partition walls.
Red bricks can be used for
constructing internal and
external walls, structural
units, and even arches and

6. The constructionprocess is relatively quicker. The construction process
is tedious and time-
consuming.
7. AAC block prices are high for small quantities of
production.
The production cost may
be cheaper for smaller
production quantities.
8. AAC blocks may need a weather coating finish if
they are exposed externally.
Red bricks can be left
exposed without the
need for weather
coating.
9.
1. AAC blocksare more durable as compared
to traditional red bricks.
2. They also have better heat and sound
insulation.
3. The weight of the AAC blocks is around 80%
less than the traditional bricks and is more
environmentally friendly.
10.
1. Improper installationcan cause cracks in the
structure of the blocks, and this will affect
the final finish of the building.
2. The porous material of AAC blocks means
that they have to be handled carefully during
loading and unloading. ...
3. AAC block prices vary with the quantity you
order.
11.
If youare in the process of constructing your
home or a business setup, then definitely
consider using AAC blocks fully or partially
for construction.
There are a lot of advantages of these
blocks that make them a great choice for
building structures that last long.
The insulation these blocks provide are
great advantages for homeowners in India.
12.
AAC blockprices may seem to be on the
higher side initially.
However, remember that these blocks are very
large, and you will need a considerably fewer
number of blocks than traditional brick ones.
Also, if you are a builder constructing a high-
rise building, then AAC blocks end up saving
so much money for you.
Do talk to your builder and compare these with
traditional blocks before making up your mind.
