AAC Blocks
AAC Blocks TUFFBLOCKS AAC is a superior alternative to red clay bricks manufactured using fly ash mixed with cement, lime, water and an aeration agent placed in an autoclaved chamber. The resultant building material comprising of millions of tiny air pores is set and cut into blocks of varying sizes. Relatively low consumption of readily available raw materials, use of fly ash, excellent durability, energy efficiency, cost effectiveness and ability to be recycled enables TUFFBLOCKS AAC to significantly contribute to a greener environment and qualify as a "green" building material.


  • Durable

    Durable TUFFBLOCKS AAC is capable of withstanding harsh climatic conditions and remains unaffected under normal atmospheric conditions for several years.
  • Versatile

    Versatile TUFFBLOCKS AAC can be easily cut, drilled, nailed, grooved, milled, crafted and shaped with common hand tools and is readily adaptable to any type of architecture. It is available in many sizes and thickness ranging from 75 mm to 300 mm.
  • Light weight

    Light weight TUFFBLOCKS AAC is 1/5th the weight of concrete and is produced in easily handled sizes. Investment in steel and concrete is reduced as it reduces dead weight of the structure.
  • Time & Cost Saving

    Time & Cost Saving TUFFBLOCKS AAC wall construction involves 1/3rd the joints as it is 8 times the size of a clay brick, thus an overall saving of upto 66%, reduction in steel upto 27% and cement upto 20%.
  • Environment Friendly

    Environment Friendly TUFFBLOCKS AAC decreases over 50% greenhouse radiation & integrated energy and utilizes at least 70% environmental waste.
  • Acoustic Insulation

    Acoustic Insulation It’s high surface mass coupled with the mechanical vibration energy damping within its porous structure produces a construction material with exceptional sound insulation properties.
  • Fire Resistance

    Fire Resistance TUFFBLOCKS AAC is an inorganic and incombustible building material with a melting point of over 1600° C.
  • Thermal Insulation

    Thermal Insulation TUFFBLOCK AAC's unique chemical structure provides superior thermal insulation than conventional masonry.
  • Energy Efficient

    Energy Efficient The thermal insulation characteristics of TUFFBLOCKS AAC contribute to a cooler interior environment leading to greater savings in air conditioning.
  • Pest Resistant

    Pest Resistant Due to its impermeable structure it is impossible for insects and rodents to inhabit in them.
