AAC Blocks: The Best and Eco-Friendly Alternative to Bricks
In the unprecedented times of global warming, AAC blocks are an alternative to bricks and one of the best eco-friendly options for construction. Read more here.
With the changing times, everyone is transitioning toward sustainable and eco-friendly technology and products. AAC block, whose full form is Autoclaved Aerated Concrete, is emerging as the best brick alternative due to its eco-friendly features.
Aerated in the AAC means it is made using air, and that’s why it is lightweight. Moreover, the AAC block weight is lesser compared to traditional bricks. Thus, it is becoming the preferred option for wailing material. Real estate giants are using AAC block size for swift construction. Let’s talk more about AAC blocks and their usage:
Why are AAC Blocks Eco-Friendly?
As we all know, the production of bricks emits tremendous CO2 into the atmosphere, which is extremely harmful to our environment. The kiln bricks produce 15% of overall air pollution. Through thorough analysis and research, it was found that AAC blocks substantially reduce the cost of sand, cement, and other building materials by 50%.
AAC blocks do not use the topsoil, which is essential for plantation. It is made up of fly ash generated as the residue of thermal power plants. Furthermore, cement mortar consumption is 0.77 bags of cement / Cu.m, which is half compared to bricks.
AAC is reusable, recyclable, non-toxic, renewable, and porous. AAC blocks reduce environmental waste by 30%. That’s another reason why we should opt for these blocks during construction.
What are AAC Blocks Made Of?
AAC blocks are foam concrete, precast, and construction material with robust sustainability. These are formed with the aggregates of water, portland cement, calcined gypsum, aluminum powder, quartz sand, and lime.
After bringing the required material together, they are mixed and moulded. Under high pressure and heat, distinctive properties are ingrained in it.
Is AAC Block Cheaper than Bricks?
In the construction industry, conventional clay bricks have been crucial. However, with the advent of the AAC block, the real-estate kings prefer it as it is cheaper than the usual bricks used in construction. The usage of AAC blocks reduces the construction cost by 20-25%.
Are AAC Blocks Cost-Effective?
The usage of AAC blocks saves concrete reinforcement and offers savings during construction. It happens because AAC blocks pack lightweight features. Hence, steel reinforcement is not required.
Additionally, AAC blocks come in huge sizes, further reducing mortar usage. The number of joints comes down compared to traditional bricks. Also, the dimensions of AAC blocks are precise and accurate, so the plaster usage is also reduced.
Interestingly, the size of AAC blocks is seven times bigger than the red bricks. So, the time to construct a building is far less as there are fewer joints. These can be laid ⅓ rd number of joints compared to the conventional bricks. Thus, it saves 20% of the construction time. Consecutively, it saves the labor cost of constructing a building with the lesser time. People can save 40% of the price using it.
The transport cost cannot be ignored in construction since AAC blocks are three times lighter than the bricks. So, it saves freight charges that we may have to pay while getting it commuted through road transportation. Thus, it is way cheaper.
Is AAC Block Waterproof?
AAC blocks have macro-pores inside. Thus, they have low water absorption quality. The feature makes them moisture-proof compared to the bricks. So, using it near the bathroom and kitchen area is beneficial for buildings or homeowners.
How to Keep AAC Blocks from Cracking?
It is recommended that before applying AAC blocks in construction, we should get them tested in a laboratory. It will ensure the quality and prevent any potential cracks in the future.
Do AAC Blocks Require Curing?
The best quality of AAC blocks is we do not need to cure them using any material. That’s the reason people prefer them. The AAC block density is such that there are no loopholes. Once applied during the construction, the mortar takes up to 4 hours to dry.
AAC is hardened by autoclave steam. During curing, the inside temperature of the autoclave should be 177 degrees. Moreover, the essential pressure should vary around atmospheres 10-12.
How to Repair a Crack in an AAC Block Wall?
The correct products should be used to ensure that AAC block disadvantages such as a crack can be dealt with. The crack filling material can be used because the cracks are usually non-structural. The catalog of the product should be read carefully to use the material wisely. We need to make a paste and apply it gently like a plaster. However, ensure the cracks are not beyond 2-3 mm.
Before starting construction, ensure the bricks you are using are eco-friendly. Eco-friendly bricks are one of the reasons the construction world is quickly adapting to AAC bricks over traditional bricks.
