Modern construction often uses aerated concrete because of its lightweight and insulating qualities. To ensure stability and durability when working with this material, however, you’ll need to use certain fasteners. For any construction project using aerated concrete, it is essential to understand the various types of fasteners that are available and how to install them correctly.
The various fasteners made for aerated concrete will be discussed in this article, ranging from conventional to specialty choices. We’ll also go over useful installation advice that will help you get trustworthy and safe outcomes.
Understanding how to handle fasteners for aerated concrete will improve the effectiveness and efficiency of your projects, regardless of whether you’re a professional builder or a do-it-yourself enthusiast. Let’s get into the crucial information you need to complete your construction tasks successfully.

Fasteners for cellular concrete
Using regular wood screws to secure objects to aerated concrete is only feasible for extremely light items like picture frames. In every other situation, unique fasteners will be needed.
Requirements for fasteners
The following factors need to be taken into account when selecting fasteners for aerated concrete:
- Density of wall blocks, indicated in the product marking by numbers after the letter D. The larger it is, the fewer pores in the material, and the stronger it is. The load limit when pulling out the fastener depends on this indicator, and the manufacturer"s instructions on the packaging contain this information.
- The parameters of the fastener are its length and diameter. The larger they are, the greater the load it can withstand. The load-bearing capacity must also be indicated on the packaging or in the certificate.
- Corrosion resistance. This parameter is especially important when fastening to aerated concrete is carried out from the side of external walls or in unheated rooms. Steel hardware must be covered with a protective layer.
This is of great importance! If fasteners for aerated concrete are installed improperly, even carefully chosen fasteners won’t function as intended. Using a non-impact tool, such as a brace or a hand drill with a special punch, to drill holes in the base is crucial.
Fastener options
Let’s examine the fasteners that are most frequently utilized with aerated concrete in more detail.
Let’s begin with the conventional kinds:
Other variations of each of these elements may exist that are not represented in the table’s images. For instance, nylon is used to make turbo dowels with self-tapping threads.
Additionally, expansion four-petal toothed dowels made of galvanized steel. When the screw is inserted, their segments slide apart to the sides and bite into cellular materials with consistency.
- If you need to fasten shelves, aerated concrete must be carefully drilled at a right angle, insert a dowel into the hole and screw a screw into it.
- And to hang a light picture or install an electric switch, a regular self-tapping screw screwed in at an angle of 45 degrees to the wall is enough.
- If you need to ensure reliable fastening of heavy equipment or install a metal entrance door, it is best to use chemical anchors.
When installed, they are capsules composed of organic and synthetic polymers and resins that form monolithic holes in aerated concrete walls, securely enclosing a metal rod or threaded stud.
The adhesive base’s resistance to thermal expansion, remarkable dependability and durability, and resistance to harsh environments are some of the benefits of this type of fastening.
Kindly take note. Since pulling such fasteners out of the wall will be impossible, markings for them must be done very precisely and carefully. But this also holds true for additional aerated concrete hardware.
When using chemical anchors for fastening, no particular training is needed; you can accomplish everything with your hands.
- A hole of the required depth is drilled in the wall, its bottom is slightly expanded by oscillating movements of the drill;
- Construction dust is blown out of the hole, and a bushing is inserted into its neck;
- The cavity is filled with adhesive mortar using a mounting gun;
- An anchor rod is immediately installed into it;
- After the mortar has hardened, fastening can be carried out.
Although these fasteners cost more than other varieties, there is no question about their dependability.
For stability and longevity when working with aerated concrete, selecting the appropriate fasteners and comprehending how to install them are essential. This article examines the different kinds of fasteners that work well with aerated concrete and offers clear instructions on how to install them. Effective and dependable results can be achieved by using the right fasteners and techniques when securing fixtures, structural components, or other elements.
Fastening building structures to aerated concrete
Not only must wires and pipes be fixed on such delicate walls, but also bulky components like ceilings and roofing. In these situations, a more substantial solution is required; screwing screws into aerated concrete is not the answer.
It is typically done even while the walls are being installed, when a monolithic reinforced concrete armored belt is installed at that stage of the building process. Studs and other embedded components are inserted into it during the pouring process, after which the fastening is completed.
Should you, for whatever reason, fail to provide an armored belt or parts embedded in it, the fastening process will only be done using chemical anchors.
| Type of Fastener | Installation Method |
| Plastic Anchors | Drill a hole, insert anchor, and screw in the fastener. |
| Metal Wall Plugs | Drill a hole, insert plug, and screw in the fastener. Ideal for heavier loads. |
| Expansion Bolts | Drill a hole, insert the bolt, and tighten. Expands to secure the fastener. |
| Concrete Screws | Drill a hole, and screw directly into the aerated concrete. No anchor needed. |
| Hollow Wall Anchors | Drill a hole, insert the anchor, and screw in. Expands inside the wall. |
For an installation of aerated concrete to be sturdy and long-lasting, the right fasteners must be chosen. Every kind of fastener has its own advantages, so knowing your options will help you choose the best one for your particular requirements.
Correct installation is crucial whether you choose chemical, expansion, or screw-in fasteners. Their performance and longevity will be improved by adhering to the manufacturer’s instructions and making sure the fasteners are installed correctly.
To sum up, the strength and stability of your aerated concrete structure can be greatly affected by the choice of fastener and installation technique. Making the effort to comprehend and implement these ideas will help to produce a fruitful and long-lasting result.
