Some Benefits of Using AAC Blocks You Probably Didn’t Know

A large number of construction projects throughout the world now use AAC (Autoclaved Aerated Concrete) blocks due to the abundance of benefits that they offer. They are quickly replacing traditional high-density bricks and are eco-friendly as well. More details about AAC blocks, AAC Block Manufacturers, and their advantages are discussed below.

Autoclaved aerated cement blocks, also known as autoclaved lightweight concrete, aircrete, and cellular concrete is a lightweight, precast building material which was invented in the early 1900s. Apart from providing structure, they also offer mold and fire resistance. Lightweight Block Manufacturers also produce roof and floor panels, wall panels, lintels and cladding panels made from AAC.

Manufacturing of AAC Blocks

Unlike other concrete construction materials, AAC blocks are produced from aggregates that are not larger than sand. Water, calcined gypsum, cement and lime and quartz sand are used for manufacturing AAC blocks. A very small amount of aluminum powder is also used in the manufacturing process. In many parts of the world, fly ash which is generated at the thermal plants and have an abundance of silica in it are used as aggregate.

AAC blocks are about 80% lighter than concrete blocks of the same size and have excellent thermal properties. This is due to the number of chemical reactions that take place between the materials that are used for their production. After the chemical reactions, when the forms of AAC are created, they are solid but still very soft.

AAC Block Manufacturers then cut these forms into required shapes and inserted into autoclave chamber for over 10 hours. When the AAC forms are treated with the high pressure and temperature of autoclaving chambers make the forms hard and provides them with their characteristic properties. After the autoclaving process, the panels or blocks are immediately ready for use in any construction process.

Advantages of Using AAC Blocks

•    AAC blocks offer structural capability as well as insulation in a single material and can be easily used for roofs, floors, and walls.

•    It is light in weight and has cellular properties which make it extremely easy to cut, shave, or shape them as required. Moreover, they can be readily screwed and nailed.

•    They are highly durable and have exceptional dimensional stability. The blocks are resistant to molds, rots, water and insects.

•    AAC blocks have excellent fire-resistant properties. Tests suggest that a 6-inch brick has a 3-hour rating. Moreover, as it is non-combustible, it will not give any toxic fumes or burn.

•    Even though they are light in weight, they have excellent thermal mass which provides them with air-tightness. They also have impressive sound-absorbing abilities.

•    AAC blocks that use fly ash in their production are also eco-friendly as they use waste materials that are generated at thermal plants.

•    As the blocks are much easier to install as compared to traditional bricks, they reduce the construction time.

As you can see, there are multiple advantages of using AAC blocks and panels over traditional bricks and as a result, they are in high-demand throughout the world. Do contact an AAC block manufacturer to know more about this environment-friendly, durable material.
