AAC Blocks – the key to faster construction!

If we talk about faster construction, much has been said and written about it. In today’s fast-paced world, where house affordability has become a challenge, the sole responsibility and pressure come to builders to complete the project in time which seldom happens. Homeowners feel the same pressure to get the possession of their dream house. Reasons may vary for a delayed project be it, lack of planning and use of substandard products, unskilled labor on the ground, old construction methods and many more. But, one thing that can really promise faster construction is the use of AAC blocks. It’s one of the solutions to a speedy construction where a structure can be erected within a predefined time frame in favorable conditions.

What are AAC Blocks?

AAC stands for autoclaved aerated concrete. These blocks compose of fly ash mixed with calcined gypsum, lime, quartz sand, water, and an aerating agent which are mixed together to form tiny pores. It is due to these pores, AAC blocks are light-weighted ones that offer porosity and portability. These blocks are also known as autoclaved cellular concrete(ACC) and autoclaved lightweight concrete(ALC).

AAC Blocks were first perfected by a Swedish architect and inventor, Dr. Johan Axel Eriksson who worked with Professor Henrik Kreuger and patented the process in 1924. These blocks can be used for interior as well as exterior construction and can be coated or painted to protect the layers from an external element. Along with its quick and faster processing, AAC blocks are non-toxic, renewable, and eco-friendly that makes it the favorite of the construction industry.  These blocks can be cut, sanded, or routed according to the requirement using standard power tools with carbon steel cutters.

Benefits of AAC Blocks!

Apart from the above properties, these AAC blocks come with numerous other benefits that make it a preferred choice for home construction. The five major benefits of these blocks are:

Fire-resistant: Since these blocks are non-combustible, AAC blocks can withstand direct fire exposure up to 6-8 hours depending upon the thickness.

Pest-resistant: AAC blocks consist of inorganic materials in its composition that helps in preventing the formation of termites or any other pests.

Light-weighted: AAC blocks are almost 5-6 times lighter than the conventional bricks. During the manufacturing process of AAC blocks, it forms a cellular structure that helps tiny air cells transmit into the blocks making its light-weighted. The density of these blocks usually ranges between 450-650 kg/m3.

Resistance to earthquake: Since the effect of the earthquake is directly proportional to the mass of the building, AAC blocks being light-weighted results in a better steadiness of the buildings. Hence, construction using AAC blocks are more reliable and safe.

Soundproof: The sound transmission class(STC) rating of AAC blocks is up to 47db that helps in blocking any major sounds and disturbance. Here again, the porous structure of these blocks helps in achieving this property.

AAC blocks are versatile and can easily adapt to any structure and design of architecture. Homeowners and builders must definitely consider AAC blocks for their construction. Not only are they an easier and faster way of construction, but the properties it comes with help in great cost-saving.
