AAC Blocks

Autoclaved Aerated Concrete (AAC) was first developed in the mid-1920s by Swedisharchitect and inventor, Dr. Johan Axel Eriksson, working in collaboration with Professor Henrik Kreuger at the Royal Institute of Technology.Patented in 1924, production began in Sweden in 1929. Over time, AAC spread across Europe, then to China, and reached India in the late1990s, with widespread adoption accelerating in the last decade.

We manufacture fly ash- and sand-based AAC blocks designed for masonry work, available in various sizes to suit diverse project needs.

Brixo Blocks are lightweight, durable, and eco-friendly walling materials made from natural raw materials such as sand, fly ash, cement, lime, gypsum, aluminium powder, and water.

Produced  in accordance  with BIS standards, Brixo Blocks undergo strict quality checks to ensure consistent performance for non-load-bearing masonry.

The Brixo wall acts as an effective environmental separator, keeping the outside out and the inside in, making AAC one of the most preferred walling solutions in India today.

AAC Blocks

Brixo AAC Blocks manufactured in Gujarat provide many benefits. It is a well-known brand name for quality and durability, which means that the blocks used to build your home will be of high quality and last for many years. While regular concrete blocks are strong but heavy in weight, AAC Blocks are strong but lightweight with 1/3rd the density of clay brick it can be laid much quicker, saving time and building costs. Being more resilient to damage helps reduce wastage during transportation.

AAC Blocks are strong, superlight, non-combustible green building materials resistant to termites, rodents, pests, and fungal growth. These blocks offer effective & practical solutions for the current building regulations and are manufactured using the latest technologies at India’s most advanced AAC facility. It accelerates construction by up to four times compared to clay bricks due to their size, dimensional accuracy, and easy workability. Brixo AAC Blocks are ideal for residential, Institutional, hotel, Industrial, and commercial project applications. Its versatility and lightweight handling make it an ideal material to work with for external and internal walls. Brixo Blocks ensure a safe, durable, and comfortable living environment. The blocks are easy to install, nail, drill and cut for pipes and conduits.

Help & FAQ
What is BRIXO Autoclaved Aerated Concrete(AAC) Blocks?

It is a lightweight masonry made of fly ash, lime, gypsum and cement, and autoclaved at high pressure. During the chemical process millions of tiny bubbles are formed causing the mixture to rise in a manner similar to bread rising. After the casting is set, it is cut into the panel or block dimensions by pulling it through wires strung on a loom. The casting is then fully cured in a large steam chamber called an autoclave.

Non-polluting Manufacture- Autoclaved aerated concrete manufacturers use a closed-loop manufacturing process, so that nothing is ever released other than clean steam. Product trimmings, slurry and water are reprocessed, and steam is reused whenever possible. Resource Efficiency- The end product is approximately 80% entrained air and 20% mass. Thus 5 parts AAC are produced from just 1 part raw materials. Low Energy Consumption throughout Lifecycle- The total energy consumption to produce is comparable less building materials. When installed, AAC results in tremendous energy savings for heating and cooling the building. Healthier Indoor Air Quality- AAC products are an excellent choice for the chemically sensitive because autoclaved aerated concrete does not offgas.

AAC materials are environmentally-friendly, and LEED does recognize this. Please note however, that LEED certification is based on the construction project, not a single material. LEED recognizes autoclaved aerated concrete products in the following manner: Recycled content (applicable to AAC blocks containing fly ash and copper mine tailings); Reduced energy consumption; locally sourced products (if applicable to project), and locally sourced raw materials.

In India AAC block are well accepted by developers and contractors because of AAC plants can able to produce very large quantities of products so availability and unit pricing is competitive with other building materialsthroughout the project. Along with the ever increasing costs of laborand delay in project, make AAC more attractive now than it has been in the past.

BRIXO reduces the quantity of materials required for masonry work and labor needed to build a building. It has many benefits some special properties of heat resistance and insulating qualities. In addition the construction using AAC can be 3 times faster than clay bricks. It cut to precision blocks, giving the erected wall surface evenness, which saves construction costs in terms of less usage of time and façade-finishing materials.AAC does not promote the growth of mildew and mold, and cannot be infested by termites. Rats and other pests find no home, since there is no cavity in an AAC wall. AAC performs well in seismic situations and high wind areas. It is having good properties makes it cost effective solution.

BRIXO is produced with combination of most modern and advance technology to maintain consistency and quality in production.Our quality checks and monitoring system at every stage of production makes the BRIXO best AAC product in market.

The standard dimensions are 600mm length x 200mm width x 100mm thickness. The blocks are available in a range of thicknesses starting from 50mm and 75mm, 100mm, 125mm, 150mm, 175mm, 200mm, 250mm and 300mm thick depends on availability and quantity of blocks required.

It is a life-long product as much as Clay Brick.Yes. The durability of AAC has been proven in every type of climate in the world -from Northern Finland to the deserts of the Mid-East for over 80 years.

BRIXO is Green Building Certified product by the renowned Indian Green Building Council of India. It uses recycled content. It uses 1/3 of the energy to produce the same volume compared to clay brick and ¼ the energy to produce cement. In addition it has great thermal insulating properties making it great in saving energy in warming or cooling the interior. AAC products were designed to respond to the urgent need to conserve and protect the earth’s precious natural resources.

AAC is probably the safe building product available. Tests conducted by independent laboratories show that AAC is not hazardous or toxic. It does not emit fumes or emit radiation above that of familiar foods.

You are advised to check our recommendation from our technical guide, or to view our visual installation for a quick understanding.

We recommend the erection of wall using AAC to be done using approved bonding material – Thin Bed Mortar (adhesive), which is commonly available in market. You may also consider our in-house brand BRIXOBond Thin Bed Mortar. It is specially designed ready-to-mix mortar for AAC Block masonry work. Thin-bed mortar is polymer modified Portland cement specifically designed to bond AAC blocks for interior and exterior wall construction. Just 5 mm thickness mortar bed is needed for laying of blocks. This extremely thin joint prevents heat loss and speeds installation. For best results, apply thin-bed mortar using tools for BRIXOSmart. Conventional mortar has a high cement content and strength, and is likely to shrink at a higher rate than the AAC blocks.If conventional mortar is used follow the important instructions on installation such as laying of AAC blocks, usage of proper accessories and wire mesh in opening areas.

Only use approved plaster applied properly. We recommend using BRIXOPlast, as it is specifically to be weaker than a conventional plaster mix because conventional plastering has a high cement content and strength, and is likely to shrink at a higher rate. BRIXOPlast are pre-bagged to ensure its quality consistency. A site mixed plaster may be weaker than BRIXOPlast.

Yes. When used in wet areas such as bathrooms, you should apply anwater proofing coat to the surface to prevent water ingress. BRIXO that is in contact with the ground should have a flexible waterproof membrane applied.

A range of manufacturers produce fixings specially designed or suitable forAAC blocks. These manufacturers include: Hilti, Fischer and others. They will be helpful to provide you with the details.

The lead time for standard products is typically one to two weeks. Lead time for custom products such as special size may require additional time for manufacturing. In either case, we encourage you to contact us with enough advance notice to provide ample time for your required delivery date.
