Autoclaved aerated concrete (AAC) is a type of precast concrete composed of natural raw materials. It was first developed in Sweden in the 1920s, when an architect first combined the conventional concrete mixture of cement, lime, water, and sand with a small amount of aluminum powder. The aluminum powder serves as an expansion agent that causes the concrete to rise, somewhat like bread dough. The result is a concrete that consists of almost 80 percent air. AAC concrete typically is made into blocks or slabs and is used to build mortared walls in a manner similar to that used for standard concrete block construction.
Autoclaved aerated concrete begins with the same process used to mix all concrete: Portland cement, aggregate, and water are mixed together to form a slurry. Upon the introduction of aluminum as en expansion agent, air bubbles are introduced throughout the material, generating a low-density lightweight material. The wet concrete is molded into shapes using forms, then cut into slabs and blocks once partially dried. The units are then moved to an autoclave for full curing under heat and pressure, which takes only 8 to 12 hours.
AAC concrete units are highly workable and can be cut and drilled with conventional woodworking tools, such as band saws and ordinary power drills. Because it is lightweight and relatively low-density, the concrete must be tested for compressive strengths, moisture content, bulk density, and shrinkage.
AAC concrete can be used on walls, floor, roof panels, blocks, and lintels.
• Panels are available in thicknesses of between 8 inches to 12 inches and 24 inches in width, and lengths up to 20 feet.
• Blocks come in lengths of 24, 32, and 48 inches, and thicknesses of 4 to 16 inches; height is 8 inches.
Cured blocks or panels of autoclaved aerated concrete are joined with thin bed mortar, using techniques identical to those used with standard concrete blocks. For additional strength, walls may be reinforced with steel or other structural members run vertically through spaces in the blocks.
AAC concrete can be used for walls, floors, and roofs, and its light weight makes it more versatile than standard concrete. The material offers excellent sound and thermal insulation, and is strong and fire resistant. However, in order to be durable, AAC must be covered with an applied finish, such as polymer-modified stucco, natural or engineered stone, or siding. If used for basements, the outer face of AAC walls must be coated with a thick layer of waterproof material or membrane. AAC surfaces exposed to weather or soil moisture will break down.
Interior surfaces can be finished with drywall, plaster, tile, or paint, or can be left exposed.
This is insane. We need it in Nigeria, it will sell like crazy.
If we use hydraulic pillers to lift this house which made by light weight concrete then is it give stability during flood and earthquake as well as same house which is built on ground?
I have a problem with those Ytong videos, in every 🏠 there are different approach es to connecting those Ytong blocks, one time they use triangle vertical metal supporters in the 4 corners, onetime they use horizontal, if the blocks are very wide, they won't use anything.halo?
한국이랑 시공하는게 왜 다른거같지
I think I need to move there! US is too expensive!

Is not expensive, you just build with paper in the US.
What about South Africa? Any dealers there?
Anything like this in the USA?
Google autoclaved aerated concrete. A ton of manufacturers out there.
Can this be used for large open floorplan houses..
I live in the US and i never see houses like this
this system also available in the US www.xella.com/index_en.php
Malaysia..?.
It's because the construction industry and permit system is basically a mafia. They protect each other to ensure that developers can use the sh.ttiest possible construction method and get away with it. Cheap matters. Quality is almost forbidden by regulation.
What's the cost per square meters?
Depends on location but in the UAE lightweight aerated concrete blocks price is around 45 USD / m3. For block with dimensions 600 x 300 x 200 from 1 m3 you can make around 5 m2 of wall. Core and shell for 1 m2 is around 200 USD + / -
@@cellularlightweightconcret1499 Do you mean 45 USD per m2?
Hi,
Do you have any YTONG dealers in New Zealand or Asia-Pacific?
Thanks
Try to check with the Hebel in New Zealand www.hebel.co.nz
Is this company available in Chennai
You can find similar company in Chennai i guess
