AAC Blocks

AAC (Autoclaved Aerated Concrete) blocks are special bricks made by mixing materials like cement, lime, fly ash, and water in the right amounts. This mix is then poured into molds and treated with high-pressure steam. The result is lightweight, strong bricks that are good at keeping your home insulated and are friendly to the environment. They’re great for construction because they’re easy to work with and contribute to making buildings energy-efficient and sustainable.

2. Commercial Buildings: AAC blocks are suitable for constructing commercial structures such as offices, malls, and hotels. Their versatility allows for the creation of durable and well-insulated spaces.

3. Industrial Buildings: The strength and durability of AAC blocks make them suitable for industrial structures where robust construction is essential.

4. Partition Walls: AAC blocks are often used for internal partition walls in both residential and commercial buildings. Their lightweight nature simplifies the construction process.

5. Exterior Walls: AAC blocks serve as excellent materials for exterior walls, providing insulation and contributing to the overall energy – efficiency of a building.

6. Load-Bearing Walls: Due to their strength, AAC blocks are often used in load-bearing wall systems, providing structural support to buildings.

7. Firewalls: The fire-resistant properties of AAC blocks make them suitable for constructing firewalls, enhancing the safety of buildings.

8. Soundproofing: AAC blocks have good acoustic insulation properties, making them ideal for soundproofing walls in buildings like recording studios or residential units.

9. Foundation Walls: AAC blocks can be used in foundation walls, contributing to the stability and durability of the building’s foundation.

10. Greenhouses: The thermal insulation properties of AAC blocks make them suitable for constructing greenhouses, providing a controlled environment for plant growth.

11. Retaining Walls: AAC blocks are used in the construction of retaining walls due to their strength and ability to withstand lateral pressure.

These diverse applications showcase the versatility, durability, and energy efficiency of AAC blocks, making them a popular choice in modern construction.

The lightweight precast foam concrete building material known as Aerated Concrete (AAC), also referred to as Autoclaved Cellular Concrete (ACC) and Autoclaved Lightweight Concrete (ALC), was created in the middle of the 1920s and offers a number of advantages including structure, insulation, fire and mold resistance, and more. As it is composed of 65–70% sand and fly ash (by weight), it is also an environmentally beneficial product. Due to their numerous attractive qualities, AAC blocks have become extremely popular in Northern, Western, and Southern India. Almost 80% of new buildings uses AAC blocks instead of the more conventional fried clay bricks. Since 2012, it has been gaining traction in the Northeast with the intention of totally eliminating the usage of conventional fried clay bricks.

Midway through the 1920s, Dr. Johan Axel Eriksson, a Swedish architect and inventor, collaborated with Professor Henrik Kreuger at the Royal Institute of Technology to improve AAC. In 1924, the process was patented. 1929 saw the start of production in the Swedish town of Yxhult. Later, “Yxhultbolaget” developed into Ytong, the first registered construction materials brand in history. Josef Hebel, a technician and creator of the company based in Memmingen, is the man behind the second major international cellular concrete brand, Hebel. In 1943, Germany’s first Hebel plant began for business.

Ytong autoclaved aerated concrete was first created in Sweden using alum shale, which was advantageous to employ in the manufacturing process due to its flammable carbon concentration. Sadly, there is not much natural uranium in the slate resources used to make Ytong in Sweden. As a result, the material releases radioactive radon gas into the structure. After 1975, Ytong used new recipes containing only quartz sand/fly ash, calcined gypsum, lime (mineral), cement, water, and aluminum powder to produce a new type of aerated concrete blocks that did not contain alum slate. As a result, the issue of radon exposure from this raw material was resolved. Since then, all producers worldwide have been using cutting-edge techniques to produce this white autoclaved aerated concrete using identical recipes.
