- Опубліковано 6 вер 2017
- Autoclaved Aerated Concrete, also known as AAC or aircrete, is a green precast building material present in the global market for over 70 years. AAC blocks and AAC panels are produced in hundreds of plants around the world, AAC is extensively used in residential, commercial and industrial construction.
AAC is an eco-friendly building material, made from natural raw materials such as: sand (or fly-ash), cement, lime, gypsum, aluminium powder and water. This mix creates an aerated concrete providing insulation, structure and fire protection in one lightweight product.

Excellent
how well does this stand up to hurricane's or a branch falling off a tree?
The ALC Wall panel can withstand positive wind force of 2,400 N/m2 and a negative wind force of 1,600 N/m2. Using the Fastening System of a Rocking Wall Method. Easily can comply with strictest building code of any country. Ex: Southern Part of China Hainan Province has the highest +wind load design of 800 N/m2.
Good information

Will Airkrete stand up to an earthquake?
Uh, nice try. That Aluminum powder used in the creation of Aircrete.... That needs to be tested because aluminum is a carcinogen nomatter the vector for how it's introduced into the human body. Does Aircrete produce vapors when in contact with sunlight or heat? If vapors are produced do those vapors contain aluminum?
AAC is non-toxic and does not emit any gasses. Hence, no vapors detrimental to humas health are produced. AAC is used since the 1930's first in Europe and by now in virtually every country in the world. All tests have been performed and all approvals on every level long received.
Does anyone know if AAC can be used in 3D printing machines and Can it be altered to include recycled plastics to tackle pollution as well as the affordable housing issues?
No, It would be expensive, and required very big vacum oven
Hi Undal Tech, AAC manufacturing is a rather sophisticated production process that requires chemistry of binders, sand and aliminium to act together in a controlled temperature environment. Hence, AAC can be "printed". Standard aerated foam concrete cane be but it is NOT autoclaved and in essence a totally different building material that has limited use.
Can it be used as a refractory brick in a kiln, where temperature reaches 1200degree celcius
Dear Kashif, in practice, the fire resistance of AAC is more than ordinary dense concrete. AAC does not support combustion and does not spread fire.. There are some test results that we would like to share with you, can you please reach out to us by sending an e-mail to our info@aircrete.com address?
How difficultly is it to set up a small plant and at what cost?
Hello Harvey, can you please send info@airctete.com a short email? So that we can reply you back individually..
What reinforcement do the manufactured items 1:15 each have, for example do the lintel have steel in them?
Dear Mr. Archer, we really like to answer all your questions about AAC, can you please contact us via email? info@aircrete.com
@@AircreteEuropeOfficial What happens to the Aircrete ingredient of Aluminum powder? Has it been tested because it's a known fact in the medical world that Aluminum if it can find a way into the human body acts as a carcinogen. Aluminum is a carcinogen. That's why there's cancer research on people who use deoderants for example that have aluminum in it. Just curious.
@@DylanBegazo The Aluminum powder mixed with the lime slurry is just a catalyst for producing millions of air bubbles in the AAC/ALC initial curing stage thus consuming the aluminium in the process. Further more the cake will be put on a Autoclave Oven producing a chemical reaction the material becomes a new stronger material that occurs in nature called Calcium Silicate Tobermorite (Roman Concrete). Eliminating completely the carcinogen properties of Aluminium powder in the process.

@@alchaus there is now what called CLC blocks to witch they dont use the aluminum powder to make theme , is t better and what could be the difference between AAC and CLC and whos a better product !,? thnk yu
is this waterproof? if not how do you waterproof aircrete?
Aerated is now waterproof product. You can apply cement for finishing touch for outdoor wall or any other alternatives.
Though it has the superior water permeability and moisture breathable properties. You can waterproof the joint of the ALC panels with a backing Rod and a flexible caulking sealant on top of it. It is also advisable to use a polyurethane spray or over latex paint for the finishing.
What's the lime, please?
limestone
Dear Ozi Sie, the lime used in the production process is quick burnt non-hydrated lime, reach in CaO (advised >92%). It has to be in a pulverized form already which is gained by dry milling limestone.
Will it stand up to an earthquake?
There is a tech called ALC Rocking Wall Panel using specialized Fastening System develop in Japan. Yes can withstand Strong Earthquake Tried and Tested for many decades in that region.
Hi Horse237, AAC material on itself is not earthquake proof, just like any other building material. It is the building design that makes structures earthquake proof and yes, AAC is widely used in Japan, Indonesia, Mexico, Turkey, etc for (non)load bearing walls for example
It's same to prefabricated method??
Hi Ram, AAC is fully prefabricated at the factory site and then shipped to site for assembly.
