Largest Manufacturer Of AAC Blocks In India.

Why CONECC AAC Blocks?

Conecc is the largest manufacturer of AAC Blocks in Karnataka. Autoclaved Aerated Concrete (AAC) blocks are perfect for foundations, inner leaves of cavity walls, dwelling partitioning walls, plus internal, external, and firewalls in both load-bearing and non-load-bearing designs. Fly-Ash building blocks are proven as being highly efficient for both house construction and commercial and industrial buildings as well.

In addition to it’s versatility and energy efficiency properties, Lightweight blocks are characterized by their ease of working and construction. It can easily be sawn even with a hand saw to meet the required AAC block size. This results in higher construction speed which may deliver cost savings. Notable savings can also be made in faster weatherproofing, lower scaffolding costs, and less on-site waste. In addition, when using the thin-bed joint application, you use up to 5 times less mortar.  AAC block’s weight is 33% lighter compared to traditional bricks and depending on the project design, savings of up to 20% in structural costs can be achieved, due to the reduction of dead load.

Enhanced Protection Against Natural Disasters with Conecc AAC Blocks

Conecc AAC blocks are non-combustible and possess a fire-resistant power that can bear up to 1400° Celsius. On the other hand, the thermal mass and tiny air pores of AAC blocks offer excellent thermal insulation, which helps to reduce the costs of heating and air conditioning of a building. Lightweight blocks also act as earthquake-resistant by offering the required strength also being lightweight reducing seismic  forces acting on the building to be less. Apart from the above-mentioned points, there are various advantages of using Conecc ACC blocks, a leading AAC block manufacturer in the industry for construction.

Uses Of AAC Blocks

Conecc AAC blocks are used to construct not only the inner leaves of cavity walls and partitioning walls, but also internal, external, and firewalls in load-bearing and non-load-bearing designs. For load-bearing applications, it is important to ensure the design is in accordance with IS 1905 and to confirm the compressive strength requirements. As a result, the building block is known for its efficiency in both house construction and commercial and industrial buildings. AAC is a concrete-based material that can be used both inside and outside of buildings. One of its advantages is that it can be routed, sanded, or cut to size on-site using standard tools such as a handsaw, cutter, grinder, etc. 

AAC is ideal for high-rise buildings with high-temperature variations. High-rise buildings constructed with AAC require less steel and concrete for structural members due to their lower density. Because there are fewer joints, the amount of mortar required for laying AAC blocks is reduced. Similarly, the material required for installation is reduced due to AAC’s dimensional accuracy. AAC’s increased thermal efficiency makes it suitable for use in areas with extreme temperatures, as it eliminates the need for separate materials for construction and insulation, resulting in faster construction and cost savings.

Most buildings constructed with AAC Blocks use cement mortar that is One Head Pan of Cement and Six Head Pans of sand or crusher (M-sand) (1:6 Cement: Sand Ratio or pre-mixed mortar). If required, AAC Block Adhesive or Thin-Bed Mortar can also be used.

AAC (Autoclaved Aerated Concrete) blocks are special bricks made by mixing materials like cement, lime, fly ash, and water in the right amounts. This mix is then poured into molds and treated with high-pressure steam. The result is lightweight, strong bricks that are good at keeping your home insulated and are friendly to the environment. They’re great for construction because they’re easy to work with and contribute to making buildings energy-efficient and sustainable.

Aerated Concrete (AAC), also known as Autoclaved Cellular Concrete (ACC), and Autoclaved Lightweight Concrete (ALC), is a lightweight, precast, foam concrete building material invented in the mid-1920s that provides structure, insulation, fire and mould resistance, and a variety of other benefits. It is also an environmentally friendly product, as it is made with 65-70% sand/fly ash (by weight). AAC Blocks have gained massive popularity in Northern, Western, and Southern India due to their many desirable attributes, with nearly 80% of constructions using AAC Blocks as a replacement for traditional fried clay bricks. It has been gaining popularity in the North Eastern region since 2012, with the goal of completely replacing the use of traditional fried clay bricks.

Dr. Johan Axel Eriksson, a Swedish architect, and inventor perfected AAC in the mid-1920s while working with Professor Henrik Kreuger at the Royal Institute of Technology. The method was patented in 1924. Production began in the Swedish town of Yxhult in 1929. “Yxhultbolaget” later became the world’s first registered building materials brand: Ytong. The second major international cellular concrete Hebel brand can be traced back to Memmingen-based company founder and technician Josef Hebel. The first Hebel plant in Germany opened in 1943.

Ytong autoclaved aerated concrete was originally produced in Sweden with alum shale, whose combustible carbon content made it advantageous to use in the manufacturing process. Unfortunately, the slate deposits used for Ytong in Sweden contain very little natural uranium, causing the material to emit radioactive radon gas into the building. After 1975, Ytong produced a new type of aerated concrete blocks that did not contain alum slate by using new recipes containing only quartz sand/fly ash, calcined gypsum, lime (mineral), cement, water, and aluminium powder, and thus the problem of radon exposure from this raw material was eliminated. Since those days, the production of this white autoclaved aerated concrete has been cutting-edge, and similar recipes are used by all producers around the world.

1. Autoclaved aerated concrete has a low environmental impact throughout every phase of its life cycle, from the processing of raw materials to the disposal of aerated concrete waste, thanks to its great resource efficiency. 

2. Aerated concrete block production uses five times less raw resources per meter cube of finished product than other building material production because of ongoing efficiency advancements. No raw materials are lost during production, and all production waste is recycled back into the production process. 

3. Aerated concrete production uses less energy than all other masonry products, resulting in a decrease in the consumption of fossil fuels and related carbon dioxide (CO2) emissions. Because steam curing occurs at relatively low temperatures and the hot steam produced in autoclaves is reused for successive batches, the curing process also uses less energy.
