Swedish Architecture made AAC (autoclaved aerated concrete) blocks in the 1920s.
Although these blocks look like bricks made with concrete to look at, they are not made entirely of concrete mix.
AAC blocks are made of compounds such as Cement, Sand, Gypsum, Limestone, and Water.
These are factory-made bricks. At present some small plants are also making these bricks.
These are the lightest bricks available on the market today.
Uses
The first use with these bricks is that the price is very low. It is cheaper than the Red Bricks available in the market.
Another unique feature is that AAC blocks are available in different sizes. Bringing in the required size blocks for our construction will speed up the construction of the house.
Walls lined with AAC blocks do not require plastering. These have smooth surfaces so you can put the wall and paint directly.
These bricks are very light in weight, float in water, and do not absorb water. These can protect the house from getting wet in the rain.
They are used in the construction of high-rise buildings due to their lightweight. This will prevent extra weight on the pillars on their home beams.
These do not require curing. Special glue for putting on joints is available in the market.
No curing so water and construction time can be saved.
Losses
These are not as strong as Red bricks, Shear walls, and Cement bricks. Very easily shattered.
If the joints do not close properly you are more likely to get it.
They have a very short lifespan compared to red bricks but in terms of price, they have their own characteristics.
