What is Autoclaved Aerated Concrete (AAC) Block?
Autoclaved aerated concrete (AAC) Blocks are an eco-friendly, lightweight and strong building product that offers to be a better solution than the traditional bricks and mortar setup. They are created in singular blocks and panels of various shapes and sizes. These blocks can be custom built in accordance with the building requirement and can provide superior strength, fire protection and sound absorption capabilities.
What type of finishes are available?
Buildings with AAC exteriors can be covered with one layer or two layers of plastering for finishing which depends on the requirements. Additionally acrylic finishes, textured layers like brick or stone and various other approved paints can be used. On the interior front virtually any kind of finishing can be used like plastering, textured paint, wood panels, tiles, Sheetrock and more.
Is AAC Block safe and time tested?
In many countries AAC is used conventionally and clay bricks are an outdated method. In Europe it is being used since 1923 and in India since the early 70s. AAC is in every way superior to the traditional method of using clay bricks. Be it fire safety, strength, longevity. It is made from non-toxic ingredients using methods that are not only within the industry norms but also within the ecological norms. Expert testing has proven that it is non-hazardous. It is safe to use and it is safe to produce.
Why is AAC a new product in India?
AAC has been in use in India since early 1970s. However at that time the cost of manufacturing it was high since it required expensive equipment as compared to the cheap brick kiln. Now the story is different. With increasing labour costs and fuel costs the brick kiln setup is at par if not higher in expenses as compared to AAC. AAC is superior in every aspect as compared to clay bricks. Hence at this point of time and the foreseeable future it is a more attractive and viable option.
How do you hang heavy items like cabinets or shelves on AAC walls?
AAC blocks are singular structures, they are less dense that the standard concrete and are still capable of securing heavy items. Fasteners can be used just like that in a standard concrete wall and they can be driven in with a heavy hammer instead of wasting electricity using specialty drills. Such setup can be done virtually anywhere on the walls. There is no need to find studs for hanging heavy objects.
How AAC Block wall masonry is cost effective in comparison to brick wall masonry?
A standard AAC block is 9 times the size of traditional bricks. This leads to fewer joints which in turn consumes less amount of cement. Since AAC blocks are factory products they tend to have a better finishing and are manufactured very precisely to the specifications. Due to the larger size and lighter weight the transportation and construction is faster. Labour cost is comparatively lower.
How is concealed wiring installed in AAC walls?
The process is very easy. After the walls are built the electrician draws out where the wires will go. A manual or electric router is the used to carve out the channels. After the electrician is done with the installation of the wires regular plaster can be used to fill it up and a smooth finish can be given to it. Given the composition of AAC blocks this process is quick and easy. If in future any changes are required they can be easily made.
Why is AAC Block considered as a Green Building product?
Eco-Friendly This product takes pride in the fact that it is produced from recycled industrial waste; fly ash. It’s made up from non-toxic ingredients. The process of producing AAC is clean and there is only one by-product; steam. Also, the total energy consumption for producing Suryshree blocks is less than 50% of what it takes to produce other building material. The Indian Green Building Council has certified AAC blocks to be green building material.
Energy Efficiency Suryshree AAC blocks prevent larger energy consumption. Firstly while its production and secondly by thermal insulation. The product being lighter than its ageing counterpart, the bricks are easy to transport and manage. The overall effort taken to construct using AAC blocks is much lower than that of using bricks.
Cost Effective Suryshree Blocks cuts down the operating cost by 30% to 40%. It requires lesser number of joints ensuring less usage of steel and concrete and thereby reducing the overall construction cost by 2.5%. Excellent insulation cuts energy cost by 30 %. Variety in sizes of blocks helps an increase in the carpet area. Wall painting and plastering last longer since efflorescence does not affect AAC. This translates into lower maintenance costs.
