AAC Blocks

Introduction of AAC Blocks

AAC BLOCKS MANUFACTURER & SUPPLIER IN INDIA AAC or Autoclaved Aerated Concrete first came into being in 1923, thanks to the efforts of Swedish Inventor Johan Axel Eriksson. The AAC is a cost effective and environment--friendly substitute of red clay bricks as construction material for making walls.

Information about the excellent properties of AAC, that includes excellent thermal and sound insulation properties along with light-weight yet high load bearing capacity has now spread across Europe and beyond, leading to the demand of AAC. These blocks and panels have low cost of construction and are energy-efficient manufacturing and installation.

AAC Blocks


Magicrete is a leading AAC blocks manufacturing unit in India. Magicrete Building Solutions is India's frontline manufacturer & supplier of AAC Blocks, a technology that has turned over a new leaf in the construction Industry. A pioneer in green building materials, we were founded with the vision of introducing prefabricated construction technologies to the Indian construction and infrastructure industry. We are regarded as a reliable producer of these blocks with two manufacturing AAC Block Plants in India: Gujarat and Haryana to cover the strategic markets of West and North India respectively.

Magicrete is a part of a conglomerate that has an aggregate turnover of over Rs. 5 billion and is into sectors like chemicals, real estate and textiles. Asserting on innovation, we have an R&D team fully equipped with the required facilities. We have also put in place processes to trace each batch of product.

Features & Advantages

Cost Saving
Cost saving in the execution:

AAC blocks manufactured by Magicrete weigh almost 80% less than conventional bricks. This means that the deadweight of the structure is considerably reduced. Thanks to the reduced deadweight, usage of steel and cement comes down considerably that means huge cost savings. The savings can be almost 30% which can be increased even more by using MagicBond for joining block. In place of cement plaster, MagicPlast should be used. As MagicPlast requires curing time of just 2 hours compared to a week of cement, the water consumption and turnaround time is considerably reduced. Inner structures of AAC blocks have the same insulation and strength as clay bricks increasing the overall carpet area of the structure.

Light Weight
Light Weight:

Presence of uniform air pockets in AAC blosks results in significantly less weight compared to the clay bricks. This leads to not only lower costs in transportation but also in lower dead weight of the structure and hence contributing to lower requirement for steel and cement in building the structure.

High Strength
High Strength:

AAC blocks have the compressive strength in the range of 3.5-4N/m2 compared to clay bricks that have just 2.5-3N/m2. The blocks can be efficiently used as a building material for hospitals, schools, high-rises and other structures.

Earthquake Resistant Fire Resistant
Earthquake and Fire Resistant:

AAC blocks produced by Magicrete can be very effective against fire and meet stringent requirements regarding fire safety. It can withstand fire up to 1200°C. The material is designed to withstand fire up to 1200°C. Cellular air pockets contribute to the thermal transmittance which is 60% of the clay brick. It has outstanding thermal insulation and can withstand high heat/frost conditions very effectively. On the ambient temperatures, the impact is low. This adds to energy efficiency as the cooling and heating requirement of such structures is quite low.

Pest Resistant
Pest Resistant:

As the construction material is devoid of organic content, AAC provides superb resistance against common pests and even molds.

Energy Efficiency
Energy Efficiency:

When it comes to thermal rating, AAC blocks are ahead of the substitutes. The blocks are walling material of choice now in LEED certified constructions. Usage of AAC blocks in India may result in averting 200mn tones of CO2 emissions into environment. This translates into a saving of $20 Billion every year.

Water Barrier
Water Barrier:

The macro pores in AAC structure are uniformly spread all over the blocks. Capillary action is blocked by these pores and absorption of water in AAC blocks is minimal. Regarding water seepage and absorption, AAC blocks are simply excellent.

Sound Proof
Acoustic Properties:

AAC blocks produced by Magicrete have outstanding sound reduction index. Sound Reduction Index is used at global level for assessing the performance of acoustic properties of partition structure. These blocks have very low sound absorption index of A0. This means that virtually all sound is reflected. This also results in a very low sound transmission index of B3. This shows, sound traveling through AAC gets dissipated and is not transmitted.

Ease of working
Ease of working:

A major advantage of AAC is that it is very easy to use and work with. Common wood-cutting tools such as saws, drills etc. can be used on the blocks


As the size of AAC blocks is considerably larger than the clay bricks, fewer blocks are required per installation. This reduces the installation time to a great extent. Masonry involved is also reduced and the time to finish also comes down.
