Product Description
Autoclaved Aerated Concrete
Autoclaved aerated concrete (AAC) is made with fine aggregates, cement, and an expansion agent that causes the fresh mixture to
rise like bread dough. In fact, this type of concrete contains 80 percent air. In the factory where it is made, the material is
molded and cut into precisely dimensioned units.
Cured blocks or panels of autoclaved aerated concrete are joined with thin bed mortar. Components can be used for walls, floors,
and roofs. The lightweight material offers excellent sound and thermal insulation, and like all cement-based materials, is strong
and fire resistant. In order to be durable, AAC requires some type of applied finish, such as a polymer-modified stucco, natural
or manufactured stone, or siding.Key aspects of AAC, whether designing or building with it, are described below:

Advantages
* Autoclaved aerated concrete combines insulation and structural capability in one material for walls, floors, and roofs. Its
light weight/cellular properties make it easy to cut, shave, and shape, accept nails and screws readily, and allow it to be
routed to create chases for electrical conduits and smaller-diameter plumbing runs. This gives it design and construction
flexibility, and the ability to make easy adjustments in the field.
* Durability and dimensional stability. A cement-based material, AAC resists water, rot, mold, mildew, and insects. Units are
precisely shaped and conform to tight tolerances.
* Fire resistance is excellent, with eight inch thick AAC achieving a four-hour rating (actual performance exceeds that and meets
test requirements for up to eight hours). And because it is noncombustible, it will not burn or give off toxic fumes.
* The light weight means that R-values for AAC are comparable to conventional frame walls, but they have higher thermal mass,
provide air tightness, and as just noted, are not combustible. That light weight also gives a high sound reduction for privacy,
both from outside noises and from other rooms when used as interior partition walls.
But the material does have some limitations. It is not as widely available as most concrete products, though it can be shipped
anywhere. If it has to be shipped, its light weight is advantageous. Because it is lower strength than most concrete products or
systems, in load-bearing applications, it must typically be reinforced. It also requires a protective finish since the material is
porous and would deteriorate if left exposed.

Installation, Connections, and Finishes
Due to the similarity to traditional concrete masonry, autoclaved aerated concrete units (block) can be easily installed by
concrete masons. Sometimes, carpenters get involved in installation. Panels are heavier due to their size and require the use of a
crane for placement. Manufacturers offer training seminars, and it’s usually adequate to have one or two knowledgeable installers
on small projects. Depending on the type of finish selected, they can be directly adhered or mechanically attached to the face of AAC.

Sustainability and Energy Considerations
Autoclaved aerated concrete offers both material and performance aspects from a sustainability perspective. On the material side,
it can contain recycled materials like fly ash and rebar, which may help contribute to credits in LEED® or other green rating
systems. Further, it incorporates such a large quantity of air that it contains less raw material per volume than many other
building products. From a performance perspective, the system leads to tight building envelopes. This creates an energy efficient
envelope and protects against unwanted air losses. Physical testing demonstrates heating and cooling savings of roughly 10 to 20
percent compared to conventional frame construction. In consistently cold climates, the savings may be somewhat less because this
material has lower thermal mass than other types of concrete. Depending on the location of manufacturing relative to the project site, AAC may also contribute to local materials credits in some green building rating systems.
