Autoclaved Aerated Concrete (AAC) blocks were developed in the 1920s to resolve the mounting pressure on forestry resources for construction purposes in the post First World War Europe. Gaining popularity globally for the last several decades, today the technology has scaled up to address the complex infrastructural challenges of the 21st century.

It is formed as a reaction of aluminum metal with a blending proportion of lime, cement, gypsum & fly ash. The hydrogen gas escaping from the reaction gives it a strong honey-comb structure. It is further cured in an autoclave under high-pressure steam to give its desired strength.

Its Lightweight reduces the dead-weight of the structure drastically. Studies show a reduction in foundation steel by 15% and cement by 10% if AAC Blocks are used.

Best in class thermal insulation results in significant savings in HVAC cost.


Autoclaved aerated concrete (AAC) block is a concrete masonry unit available in the precast form. It is a more innovative alternative to poor brick construction. We fabricate AAC blocks from aggregates of quartz sand, calcined gypsum, lime, cement, water, and aluminum powder. As a result, AAC blocks are super light in weight. As the name suggests, we cure AAC blocks in autoclaving process under controlled heat and pressure. Magicrete is the first leading AAC Company to put forward a complete walling solution for you.

There is no reason which can claim the use of AAC blocks as bad. When choosing AAC blocks, you are making sure that you are enjoying every benefit from the use of the same. AAC blocks' lightweight, energy-efficient, sustainable, thermal insulating, fire-resistant, and soundproofing properties are certainly out of the ordinary. Having a way to all these properties, you can save the construction cost to a vast extent. With the use of AAC blocks, you have ease of installation.

With the use of red clay bricks, we need to control certain noticeable drawbacks. The increase in demand for red clay bricks with a growing population has resulted in the infertility of our land. Also, due to the skyrocketing prices of kiln fuel, red clay bricks are no more budget-friendly. The AAC blocks have always proved to stay out of the ordinary due to their comparatively better compressive strength. AAC blocks are far better than bricks as they are environment-friendly, light in weight, and suitable for an all-weather construction. By choosing AAC blocks over bricks, you are taking care of the durability and overall performance.

Opted for AAC block construction? If yes, you can enjoy the rains without the worry of that disturbing water seepage through your walls. AAC blocks don’t allow for capillary action making it impervious to water. In addition, AAC blocks don’t let the water penetrate through them. This is due to the evenly distributed macropores and silicon-based additives within the AAC blocks. Therefore, if you use AAC blocks, you get better moisture protection, unlike the red bricks.

Use a drill machine and a Rawal plug to drive the screws in your AAC block wall in spaces where you need to do furniture fixing. By doing so, you ensure that you prevent any cracks after installation.

The showing of cracks in your AAC block walls may be an outcome of the following reasons: • If you are using a poor-quality block, cracks develop due to shrinkage. • If you don't carry out the curing properly. • Very few workers are acquainted with AAC wall construction. Poor workmanship can lead to cracks. • Excessive plaster thickness. • If you are applying putty immediately just after curing. • If you are subjecting your block to continuous vibrations, such as using a hammer to hit a nail. • Humid location. • The increased water-cement ratio in mortar. • The cement content isn't appropriate as specified in the design mix. • If you are using very fine ungraded sand to make mortar. • If you are using a higher grade of cement while making the mortar.

You don’t need curing for AAC blocks. There is no requirement for curing AAC blocks. The mortar used in the AAC block construction dries up quickly within 4-5 hours. The mortar then provides an excellent bond. So, the only thing you need to do after the masonry work is wait until the mortar sets. And voila, no need to cure, unlike the brick masonry.
