That is why there is a desperate need to find better building materials for houses and infrastructures today. Over 10,000 homes and 18,000 structures are destroyed because of the wildfire. There have been several destructive wildfires in some states, and it is very devastating. Wildfire has been a growing concern today. AAC might not solve such issues, but it can certainly help. With AAC, the occurring and emerging issues can be reduced. Oftentimes, standard wood-frame construction will not that useful anymore.

Storms and flooding events have become more extreme, wildfires are more very frequent these days, and even termites are more widespread. The vulnerabilities being faced today are incredibly significant and will continuously emerge and increases over the years. AAC: The Ideal Material for Resilient BuildingsĪAC is proven to offer several unique advantages in climate change when building more resilient buildings is critical.

R-values are generally lower when compare to energy-sufficient insulated walls construction.If AAC is installed in high humidity environments, interior finishes will require lower vapor porousness while the exterior finishes might require high porousness.The products can show inconsistencies both in color and quality oftentimes.Like all building materials, autoclaved aerated concrete also has some drawbacks: Economical handling and shipping compared to concrete block or poured concrete.Easier to cut for holes and chases for plumbing and electrical lines.Because it is lightweight, holding and installing it is easier.The high thermal mass can store and release energy over time.Great material for acoustic insulation and soundproofing material.Benefits and Drawbacks of Autoclaved Aerated Concreteīelow are some of the most extraordinary benefits of AAC: Interior surfaces can only be finished using plaster pile, drywall, paint or tile.The surface area of AAC concrete will break down quickly when exposed to weather or soil moisture.The AAC surface, particularly its outer face, should be coated with a very thick waterproof material layer.If AAC is utilized for basements, contractors should take note of a few things: The applied finished could be siding, natural/engineered stone, or polymer-modified stucco. Yet, for this concrete to be extra durable, AAC should be covered with one last finish. The material also offers impressive sound and thermal insulation, aside from being fire resistant and extra durable. Building with AAC ConcreteĪAC concrete is ultimately useful for floors, roofs, and walls because its lightweight has made it much more versatile than standard concrete. While AAC has relatively low-density and very lightweight, the concrete itself must be tested for bulk density, moisture content, compressive strengths, and shrinkage. For standard thicknesses, 4-16 inches, and the height should be 8 inchesįurthermore, AAC concrete units are highly workable because they can be drilled and cut with conventional woodworking tools like ordinary power drills and band saws. Blocks come in different sizes: 24, 32 or 48 inches.

Panels are usually available in a standard thickness between 8-12 inches in width.It generates low-density lighter material.ĪAC concrete can be utilized on roof panels, walls, floor, lintels, and blocks but take note below: With the introduction of aluminum as an enlargement agent, air bubbles are used for the entire material. Portland cement, water, aggregates are mixed to create a slurry. This concrete started with the same process, particularly for standard concrete block construction. Today, AAC concrete is commonly made into slabs or blocks and is utilized to build mortared walls. The latter serves as an expansion agent, causing the concrete to enlarge massively, somewhat like bread dough. Everything started when an architect has mixed the conventional concrete combination of water, cement, lime, sand with a small amount of aluminum powder. This concrete has been first developed in Sweden in the early 1920s. Introducing Autoclaved Aerated Concrete (AAC)ĪAC is a form of pre-cast concrete comprised of natural raw materials. This blog will tackle AAC, its benefits, drawbacks, purpose, etc. This particular building material offers many extraordinary benefits others tend to overlook. Autoclaved Aerated Concrete (AAC) is one of the most common forms of precast-concrete. This form of concrete is not directly poured on the site, but rather it comes in a pile of pre-cast blocks. P re-cast concrete has an outstanding place in the construction world, offering an easy, affordable, and quick way to construct walls and different structures.
