What are AAC blocks?
Autoclaved Aerated Concrete (AAC) blocks are lightweight and durable building products. First conceptualized and invented by Swedish architect and inventor Johan Axel Eriksson in 1924, AAC blocks are particularly known for their fire, heat, and sound-resistant properties. Air being the major constituent (almost 80-85% by volume), these building products are typically lightweight, weighing only a third of the more common red clay bricks.

How are they made?
Common ingredients used in the production of AAC blocks include lime, cement, sand, water, gypsum, fly ash, and Calcium oxide (commonly known as quicklime). Aluminum powder reacts chemically with these and hydrogen gas escapes into the air towards the end of the procedure. It is this chemical reaction that lends AAC blocks their distinct honeycomb structure, lightness, and other insulation properties.
Having undergone necessary molding and mixing, these are further cured in an autoclave (subject to high heat and pressure) that imparts them the desired strength and durability.

What are the advantages of using AAC Blocks?
On an average, AAC blocks are 9 times the size of regular clay bricks. This translates to superior construction speed and quality, coupled with the formidable reduction of costs - on plaster and mortar - at the site. Importantly, best-in-class thermal insulation results in increased savings of Heating, Ventilation, and Air-conditioning (HVAC) costs.

Because of its high workability and flexibility standards, AAC material is widely used across the construction of residential buildings, healthcare facilities, schools, hotels, and other industrial/commercial structures

FAQs

Autoclaved Aerated Concrete (AAC) block is a precast, lightweight, and insulating green building product used as walling material and a replacement for bricks, CLC Blocks, etc. In addition, due to solid thermal insulation, AAC blocks also use special applications such as firewalls, sound walls, roof tiling, etc. Magicrete AAC Blocks manufactures these products at its state-of-the-art plant with the latest innovations under advanced technology in Surat under the Brand name "Magicrete AAC Blocks."

AAC blocks have been in use for more than 90 years across the Globe. Structures built over 85 years ago are still standing today. However, for India, this is an evolving product.

AAC was developed in 1924 in Sweden by an architectural science lecturer looking for alternate building material with properties similar to wood, such as good thermal insulation, solid structure and easy to work, etc., and having resistance against fire and termite.

Cement, Fly ash, and Lime are the critical ingredients for making Magicrete AAC Blocks. Their curing takes place under steam curing, known as Autoclave. Due to sustainable material envelope, these products are certified under the green rating system and help builders get credit points.

Yes, Being lightweight (1/3rd weight of clay bricks), Magicrete AAC Blocks are highly recommended for high-rise buildings and help reduce the total dead load of the structure, which directly helps in structural savings up to 20%.

The strength of Magicrete AAC Blocks is as per IS: 2185-Part III which is absolutely safe and strong enough to use for any non-load-bearing walling applications.

Deflection of the beam, soil settlement to one side, the uneven placing of blocks during construction are some reasons for wall cracking. Other reasons are structural Movements due to Thermal Expansion or change in moisture content or moisture movement. To avoid such damage, you should delay the AAC blocks' use until equilibrium moisture content. For this purpose, AAC blocks must be stored 10-15 days before application. Cracks appear in all types of concrete, including clay brick. We can minimize these cracks by using some construction techniques and proper workmanship. Leveling of blocks should be accurate and must be checked using Spirit level, preferably of 2-meter length. The First Course of Blocks should have sufficient time to set, and you should provide at least 24 hours for this purpose. There should be enough time for the framed structure to cure and settle so that you can notice any change in design due to structural movement. There should be a Control Joint of 10 mm after every 3 meters from the bottom to the top of the wall. Control joint must get filled with resilient material or backer-rod, which are easier to compress. And seal with caulking. Expansion Joint Ties must be given after every 3rd course and placed between gaps of control joint. The bond beam must be passed every 1200 mm in height using reinforcement of two MS rods of 8 mm tied with 6-8 mm steel with a gap of 6" -9". The minimum thickness of the bond beam must be taken 3" with concrete cover 15-20 mm on sides. The bond beam must be discontinuous at the control joint. Steel rods must be embedded in columns 5-6 times their diameter and fixed using non-shrinkable high-strength grout. Take Cement: Sand ratio 1:4 as Mortar Mix for filling the bond beam. The reason to provide a bond beam is to give Stability and Strength to the wall. After every 3rd course, there should be wall ties between the block and Concrete column.

You can use AAC Blocks to construct all types of walls between two columns in framed structures like partition, curtain, balcony, and boundary walls.

Water Absorption Test @ 24-hour water immersion is not given in Standard of AAC Blocks IS-2185 Part-3. It is advised to test thermal insulating wall elements like AAC for Capillary water absorption. AAC is most superior for capillary water absorption compared to a conventional brick. Like Red Clay brick, AAC is not recommended in foundations and a damp environment, so a water absorption test is not applicable for AAC.

Due to different reasons, blocks may damage during transport or handling at the site. This can be used as half-cut blocks after size cutting. Indian Standard IS-2185 Part-3 Clause 8.1.1 allows slight cracks and minor chipping not larger than 25 mm and shall not be deemed grounds for rejection.

AAC Blocks are in different sizes. In Length 650, 600 mm. In Height 250,240,200 mm and in thickness 75,100,125,150,200,225 mm.

No, AAC blocks are not recommended in the Foundation, and where high dampness is there.

Since it is highly porous, its water absorption is higher than the Red Clay brick if immersed in water for 24 hours. So it's not recommended to use in specific applications like Foundation, sewer-hole, and concrete water tanks.

AAC has thermal insulating properties; its thermal conductivity is 1/5th of clay brick. So AAC conserves the heat for a more extended period and saves energy costs due to air conditioning or room heater.

Yes. IS-2185 Part-3 is the Indian Standard Specification for AAC Blocks.

No, AAC does not catch fire, and its fire Rating is 4 Hours for an 8-inch wall.

It would be best to have a Low Capacity compression testing machine of 250 KN and a Cutting Machine. High Capacity Machines of 2000-3000 KN are not recommended to use. Instead, follow the testing guidelines as mentioned in IS-6441 Part-5.

There is a difference between immediate density and oven-dry density. AAC blocks have certain moisture content in normal conditions, so their density is higher. Still, for testing purposes, we dry the sample at 105 °C for 4-5 days till constant weight is achieved, and then we obtain moisture-free density or dry density. Refer IS-6441 Part-1 for testing the oven-dry density

Autoclaved aerated concrete is highly durable. It does not rot or decay like wood or other organic materials. Also, it does not rust like metal. Termites and other pests do not eat it. AAC will not burn. The millions of tiny cells in AAC cushion buildings from the significant force, preventing progressive collapse. AAC has withstood earthquakes in Japan, the frigid temperatures of northern Europe, the harsh salt air of the French Riveria, and the hillside fires of San Francisco.

No. AAC construction provides a solid, monolithic wall system with an enclosed, non-connected cellular structure. Exterior finishes complement this structure, providing a healthy balance between moisture resistance and vapor diffusion. In addition, the positive pressure of the air conditioning system pushes water vapor out through the walls while preventing moisture penetration from the exteriors.

Yes, Being lightweight (1/3rd weight of clay bricks), Magicrete AAC Blocks are highly recommended for high-rise buildings and help reduce the total dead load of the structure, which directly helps in structural savings up to 20%.

Even though they appear to be similar, they are different products. CLC strength parameters are 25 kg per sq.cm. Whereas AAC block strength is 35 to 40kg per sq. cm. CLC cannot be cut with wires, and the edges are not accurate and easily damageable. The CLC is cured in conventional methods, and the AAC is ready for use with adequate strength at the post-production stage due to its advanced autoclaved curing process. Unlike AAC blocks, CLC blocks give rise to the release of toxic gases.
