Cost-efficient
Compared to red clay bricks, Flyash AAC Blocks provide wider surface area, easy binding and significantly reduce steel and mortar use.
Convenient Usage
Flyash AAC Blocks can be cut into any size or shape and are easy to use in odd structural angles and convenient for hammering and drilling.
Highly Durable
Flyash AAC Blocks are much stronger and durable than conventional concrete and red clay bricks.
Eco-friendly
Made with fly-ash, a thermal power plant waste, Flyash AAC Blocks are a much more sustainable and eco-friendly alternative to red clay bricks.
Lightweight
Flyash AAC Blocks are comparatively lightweight - this property reduces dead load on foundation and improves construction quality.
Effectively absorbs sound
Flyash AAC Blocks have better sound insulation that significantly lowers outside noise levels.
Earthquake Resistant
Due to their incredible durability and strength, Flyash AAC Blocks provide better safety against earthquakes.
Termite and Pest Resistant
Their inert nature helps to repel termites and other pests, keeping your structures clean and hygienic.
International Research On Flyash AAC Block
AAC is unique among construction materials for its exceptional thermal resistance and thermal inertia. (Ropelwski et al, 2019)
AAC has many advantages compared with conventional concrete, such as an advanced strength to weight ratio, a lower coefficient of thermal expansion and good sound insulation. (Hamed, 2019)
In almost all parameters, Flyash AAC Blocks are more durable, efficient and stronger than burnt clay bricks. The use of Flyash AAC Blocks reduces overall building costs and speeds up the construction process. (2014)
Flyash AAC Blocks do not allow the spread of termites and the growth of pests. (2018)
Flyash AAC Blocks are completely inorganic and hence do not generate any toxic fumes or poisonous gases harmful to the occupants.(2018)
Flyash AAC Blocks reduce operating costs by 30% to 40%, reduce overall construction costs and reduce the need for cement and steel. High insulation blocks save up to 30% in energy costs and wall painting and plastering last longer as almost nil efflorescence affects Shree Flyash AAC Blocks. This translates into lower maintenance costs.(2018)

FAQ'S
Yes. Shree Flyash offers direct factory delivery of AAC blocks to project sites. Delivery availability depends on the project location, order quantity and transportation requirements. Get in touch with the Shree Flyash team or an authorised dealer to check delivery availability for your site.
Shree Flyash AAC blocks are available in different sizes to meet different wall and construction requirements. Popular widths include 6 inch, 8 inch and 9 inch. The right size depends on your wall specification, so it is important to confirm the required block size before placing an order.
Shree Flyash AAC blocks have an average compressive strength of 4.5 N/mm², compared with the minimum requirement of 4 N/mm² under BIS IS 2185 (Part 3):1984. This makes compressive strength an important consideration when selecting AAC blocks for different wall applications.
Shree Flyash AAC blocks are tested against parameters specified under BIS IS 2185 (Part 3):1984, including compressive strength, density, thermal conductivity and drying shrinkage. For project-specific BIS certification documents, test certificates or other compliance documentation, connect with the Shree Flyash team directly.
Shree Flyash has received several industry recognitions, including ICC Corporate Governance & Sustainability Vision 2020, Global Sustainability Award 2019, CII SCALE Logistics & Supply Chain Excellence 2019, and Best Quality Excellence 2018–19 by NCCBM.
Yes. Shree Flyash AAC blocks use fly ash, a thermal power plant waste material, making productive use of an industrial by-product. AAC block construction can also require up to 70% less water than conventional red-brick construction, while thermal insulation helps reduce cooling requirements inside buildings.
AAC blocks are available in different sizes depending on the wall requirement. Common sizes include blocks measuring 600 mm in length × 200 mm in height, with thicknesses of 75 mm, 100 mm, 150 mm, 200 mm and 230 mm. The required size should be selected according to the project specification.
Common AAC block dimensions are 600 mm in length × 200 mm in height, while the thickness varies according to the wall application. Common thicknesses include 75 mm, 100 mm, 150 mm, 200 mm and 230 mm, allowing different sizes to be used for different construction requirements.
AAC blocks commonly measure 600 mm in length × 200 mm in height, with thickness options ranging from 75 mm to 230 mm. Since different wall applications may require different thicknesses, always match the AAC block measurement with the structural and wall specifications of your project.
The weight of an AAC block depends on its dimensions, so there is no single weight for every block size. Shree Flyash AAC blocks have an oven-dry density of approximately 580–610 kg/m³. The weight of an individual block will therefore vary according to the size selected.
Shree Flyash AAC blocks have an oven-dry density of approximately 580–610 kg/m³. Since blocks are available in different dimensions, the weight of each individual block varies with its size. Check the required block specification when estimating material weight for transportation or project planning.
AAC stands for Autoclaved Aerated Concrete. It is a lightweight, precast building material commonly used for wall construction. During manufacturing, the material is mixed, formed and cut into blocks before being cured under steam pressure in an autoclave, giving AAC its lightweight and insulating properties.
You can enquire about Shree Flyash AAC blocks directly through the Shree Flyash website or connect with an authorised dealer. Share your project requirements, block specifications and location to get the relevant pricing, availability and delivery details before placing your order.
Yes. Fly ash-based AAC blocks offer a more resource-efficient alternative to conventional red clay bricks by using fly ash, a thermal power plant waste material. AAC construction can also use up to 70% less water and provides thermal insulation that can help reduce cooling requirements.
