Objective and independent assessment of aerated concrete blocks – pros, cons, reviews from builders and home owners

Selecting the appropriate materials for a home’s construction or renovation is essential for ensuring its longevity and affordability. Aerated concrete blocks, also known as AAC blocks, are becoming more and more well-liked due to their combination of strength and light weight. They are produced by adding air bubbles to the concrete mixture, which lowers weight and improves thermal insulation properties.

Aerated concrete blocks appeal to both homeowners and builders for a number of reasons. Because of their lightweight design, they are simpler to handle and transport, which speeds up construction and lowers labor costs. AAC blocks are just as strong as traditional concrete or clay bricks, with comparable structural stability despite their lower weight.

The thermal efficiency of AAC blocks is one of their best qualities. Over time, the insulating effect of the air bubbles trapped in the material helps to control indoor temperatures and lower heating and cooling costs. In areas with harsh weather, this energy-saving feature is especially alluring.

But just like any other building material, aerated concrete blocks have drawbacks that homeowners and builders need to take into account. Although they provide superior thermal insulation, their acoustic qualities might not be as good as those of denser materials like bricks or solid concrete. This may have an impact on soundproofing qualities, which are crucial for both residential and commercial buildings.

Homeowner and builder reviews offer insightful information about the usefulness of utilizing AAC blocks. Many emphasize how much faster construction is and how much easier it is to install than with traditional materials. But occasionally, worries surface about how easily they could be harmed by collisions or careless handling during installation.

To sum up, aerated concrete blocks are a cutting-edge method of building that combine strength and light weight in an efficient manner. They are attractive to homeowners trying to reduce energy use and builders trying to expedite projects. Making informed decisions when incorporating AAC blocks into building and renovation projects is ensured by having a clear understanding of both the benefits and limitations through objective assessments.

Advantages

Aerated concrete is the material of choice for many Russians because it is perfect for low-rise building construction. Compared to other forms of cellular concrete, aerated concrete blocks offer numerous benefits.

• The first and often decisive advantage is the low cost of the material.
• Large blocks are light in weight, which makes laying easier, without the use of heavy equipment and lifting machines.
• Due to its large size, the house can be built very quickly (all sizes of aerated concrete products are described here).
• It is safe to live in a house made of aerated concrete, since the material is harmless – it is only one indicator behind wood in terms of environmental friendliness.
• The right brand of aerated blocks makes it possible to save on insulation, since the porous structure of the material retains heat well.
• Thanks to the good thermal insulation of the material, heating costs are saved, since heating a house in winter requires less energy resources.
• The material is easy to process; it is easy to cut out an arch or opening of any shape from it, using ordinary carpentry tools at hand.
• Aerated concrete blocks are non-flammable material and can withstand fire for a long time.
• Aerated concrete walls “breathe”, creating a favorable microclimate inside a residential building.

Flaws

Although aerated concrete has been used for decades as a dependable and tested building material, it is not without drawbacks.

• The material, despite its low density, is quite fragile, so you need to work with it very carefully and should not throw it.
• Due to the porous composition, it is difficult to hold fasteners. Only through the use of dowels and anchors can this problem be solved.
• It easily absorbs water, therefore, if the outer side of the wall has poor-quality cladding, the walls will become saturated with moisture and mold may appear. In addition, if moisture gets inside the blocks, then with temperature changes the material will collapse from the inside. Read more about the moisture resistance of aerated concrete blocks here.
• The price of aerated concrete is higher than the price of other types of cellular material.
• Ideally even geometric shapes of aerated concrete blocks are guaranteed to be available only from well-known manufacturers.
• Working with aerated blocks when constructing walls requires strict adherence to masonry technology.
• When constructing load-bearing structures, it is necessary to use reinforcement.
• Buildings made of aerated concrete cannot be built higher than 3 floors.

Is aerated block dangerous and harmful to health??

Information about the dangers of aerated concrete can occasionally be found. You must dismantle every part of this material in order to comprehend why and how a gas block is defective.

1. Cement. This material is present in all types of concrete and in the form of solutions it does not pose any harm to health.
2. Quartz sand. This natural material may contain some amount of radioactive substances, but its use in the production of any building material is under strict control, and the manufacturer must have safety certificates and sanitary and hygienic conclusions.
3. Aluminum powder (or powder). The presence of this chemical in aerated concrete scares inexperienced people the most. Aluminum powder is responsible for the most important process – gas formation and bubble formation. The conditions created convert this chemical into hydrogen or aluminum oxide, which does not pose a health hazard. It should also be taken into account that the percentage of this substance is only 0.06-0.1% of the total composition. A certain amount of aluminum compounds are present in various building materials, including clay and brick.
4. Lime. Thanks to this substance, potassium silicate is obtained during production.
5. Ash and slag. These two substances are not always present in the mixture for aerated concrete, but they are sometimes used as fillers. They may contain heavy metals (cadmium, lead), therefore, when purchasing aerated concrete, ask the supplier for documents guaranteeing the safety of the product.

Aerated concrete needs to be manufactured from premium raw materials, so it should only be bought from reputable and well-known suppliers if you want to avoid health risks.

Construction safety requirements

Although there are no health risks associated with aerated concrete as a material, you still need to follow the guidelines when using it.

Workers must wear protective gear, such as respirators and goggles, to protect their eyes and lungs when sawing, sanding, and drilling aerated concrete blocks.

When concrete dust irritates the mucous membranes in the eyes, it can cause inflammation and blindness. Additionally, breathing in dust can aggravate bronchitis or asthma.

Aerated concrete, however, does not present a health risk to those who live in one.

Understanding Aerated Concrete Blocks: Exploring the Real Benefits and Drawbacks from Builders and Homeowners. This article delves into the practical aspects of aerated concrete blocks, providing an objective assessment of their advantages and disadvantages based on input from industry experts and residents. We want to give you a clear picture of whether or not aerated concrete blocks are a good option for your building or remodeling project by looking at both positive and negative experiences.
