Weight of aerated concrete block (aerated concrete block, aerated concrete)

Aerated concrete blocks are becoming more and more common in construction because of their versatility and low weight. These blocks, also known as autoclaved aerated concrete (AAC) or aerated concrete, have various advantages over conventional building materials. They are easier to handle and transport due to their lighter weight, and their special composition offers superior insulating qualities.

The cost and overall efficiency of a construction project can be greatly impacted by the weight of an aerated concrete block. Less structural strain results from lighter blocks, which can reduce the need for foundational support and transportation expenses. Furthermore, the simplicity of installation can save labor costs and time, making aerated concrete blocks a cost-effective choice for builders.

Aerated concrete blocks are less heavy without sacrificing strength or longevity. They are appropriate for a range of building applications, including both residential and commercial buildings, because they retain strong structural integrity. Their creative design and manufacturing process are responsible for their exceptional thermal insulation and ability to withstand environmental stresses.

Anyone working in construction needs to be aware of the weight of aerated concrete blocks because it affects logistics and planning. Understanding how these blocks can streamline your construction process will enable you to make well-informed decisions and guarantee that your project reaps the benefits of this cutting-edge material.

Pros and cons of aerated concrete

Aerated concrete has several benefits, some of which are as follows:

• High thermal insulation qualities. It is considered the main advantage of aerated concrete in comparison with brick or other building materials.
• High geometric accuracy allows you to build walls with a masonry joint thickness of no more than 3-4 mm, which reduces the number of "cold bridges".
• Large dimensions and less weight compared to brick, reduce the time spent on construction by 2 or more times.
• In terms of vapor permeability, it is practically not inferior to natural wood. Breathing walls made of aerated concrete make the microclimate of the premises comfortable for humans.
• High fire resistance and immunity to aggressive environments.
• Low weight, reducing the load on the foundation.
• Environmental safety in comparison with ordinary concrete, in the production of which radioactive granite crushed stone is used.
• High (more than fifty cycles) frost resistance.

First among the drawbacks of aerated concrete blocks are the following:

• High hygroscopicity.
• Low strength of walls (probability of "cracking" due to errors in the process of arranging the foundation).
• Need for additional reinforcement of the masonry.
• Possible problems with subsequent processing.

Composition of gas silicate blocks

Because they have good diffusion characteristics, gas silicate mixture wall blocks are a wall material that you can use to create a healthy microclimate in the room. In other words, the structure "breathes," preventing the growth of mold. Which basic materials are used in the production of blocks?

As per SN 277-80, "Instructions for the manufacture of products from cellular concrete," an aerated concrete mixture comprises the following ingredients:

• Portland cement, manufactured according to GOST 10178-76, with a calcium silicate content of at least 50%., tricalcium aluminate no more than 6%. Additives are not allowed tripoli.
• Sand must meet the requirements of GOST 8736-77, clay and silt inclusions no more than 2%, quartz content of at least 85%.
• Water with technical requirements according to GOST 23732-79.
• Calcium quicklime must comply with GOST 9179-77, and be not lower than grade 3. Additional characteristics: slaking speed 5-15 min., "overburn" – no more than 2%, CaO + MgO content – not less than 70%.
• A gasifier is used – aluminum powder PAP-1 or PAP-2
• Surface-active substance (SAS) – sulfonol C.

The concept of grade D500

Autoclaved cellular concrete includes aerated concrete blocks. Their primary form during production is a parallelepiped that is rectangular in shape. In addition to ridge grooves for masonry strength and ease of use, the end sides may also have recesses for hand grips on the block.

Concrete with aeration is made up of cement, sand, lime, and water. Aluminum powder is gradually added to this mixture in a quantity that ensures the final gas block has the necessary density—in this case, D500 (d500).

Fascinatingly, a material’s strength increases with the amount of cement and sand it contains.

When lime and aluminum powder come into contact, an active release of hydrogen occurs. As the material hardens, the hydrogen forms irregularly shaped pores with a diameter of 1 to 3 mm (porosity is between 55 and 75% of the block’s total mass). Firing in an autoclave furnace gives the material its ultimate strength.

Density D500 products are utilized in the building of:

• Load-bearing walls (internal and external).
• Non-load-bearing walls.
• Partitions.
• Reinforced belts.
• Lintels.
• Chimneys and ventilation ducts.

This material is widely used for insulating existing walls and for building garages, summer kitchens, sheds, and outbuildings as well as private residential buildings up to five stories tall.

Density

The composition of finished goods determines their performance characteristics. Density has an impact on gas silicate blocks’ strength and thermal conductivity.

The material’s resistance to frost and thermal conductivity increase with decreasing density. For aerated concrete, 500 kg per cubic meter is the ideal density. Both interior and exterior wall construction work well with Grade D500.

It is important to remember that low density equals low compressive strength. Technical indicators based on material density are displayed in the table.

Type of aerated concrete blocks	Density, kg / m3	Thermal insulation properties	Application
Structural	from 1000 to 1200	Additional insulation is required	First floors
Structural and thermal insulation	from 500 to 900	Average	Wide range of use
Thermal insulation	from 300 to 500	Excellent	Does not withstand high pressure

Standard sizes of aerated concrete blocks

Because aerated concrete can be used to build both partitions and load-bearing walls, manufacturers now provide a fairly broad selection of aerated concrete blocks. Large blocks with a high bearing capacity are needed in the first scenario, while small-diameter stones are needed in the second since they are essentially unloaded.

However, it should be mentioned that every block has the same length. The parameter in this case is 600 or 625 mm. Because of this standardized production process, the amount of material needed to complete a building can be precisely calculated along its length. There are two positions for the block’s thickness (width): 200 and 250 mm. The former are typically used to build load-bearing walls, while the latter are used to build partitions. This allows stones to be installed 200 mm wide beneath load-bearing walls of one-story buildings, despite the slight difference.

However, the model range for gas silicate block height is rather broad. However, it is important to remember that not all dimensional dimensions pertaining to the product’s thickness are met by this. The following is the ratio:

• with a stone width of 200 mm, its height can be 150, 200, 250, 300 and 400 mm;
• with a width of 250 mm, the height is 100, 150, 250, 300, 375, 400 and 500 mm.

A typical size

How much do different blocks weigh?

Gas silicate block structures are widely used in building construction, reconstruction, and repair. The density of products made from this material is competitive with brick and conventional concrete, but product weight is crucial. Understanding weight properties is helpful.

• when calculating foundations;
• when determining the characteristics of floors;
• when preparing for storage of blocks in warehouses and directly at construction sites;
• for proper transportation planning, selection of appropriate transport and packaging.

There may be a 600X300X100 gas silicate block in certain instances. Because of its improved sound and thermal insulation capabilities, it is used. For low-rise and multi-story construction, the load-bearing qualities of grade 500 concrete will be adequate. A single block will weigh fifteen kilograms.

As a result, lifting it by yourself won’t be too tough.

With a size of 250X300X600, the weight of one building element will be 36 kg. Theoretically, you can lift such a product with your own hands. But it will be more accurate and precise to lay it with an assistant. The descriptions note the significant load-bearing capacity of the material. It is allowed to use it as a thermal barrier.

A 300 by 200 block, or more precisely 600X300X200, is a common block; alternative versions are 200X300X600 or 600X200X300. Its density falls between grades 500 and 700. Construction projects make use of its products. It is only necessary to use weaker grades for insulation work.

Equal to 600X250X100, 100X250X600 is also a typical building material. These blocks fit on a typical cargo pallet in a capacity of 120. Regarding 1 m2, 6.67 products are included. One structure weighs 10.5 kg, making it relatively simple to operate.

600X400X250, or alternatively 250X400X600, is another well-liked solution. This is a great choice for room partition separators and low-rise building. It is relatively light because of its cellular structure. Typically, a material’s frost resistance is 100 cycles, meaning it can be used for 30 to 40 years. Standard weight is 14.4 kg.

Aerated concrete can also be used to make portions of 600X300X250. This wall material, weighing 22.5 kg per unit, is good. Strengthening compression class B2.5–B3.5. For every m3, there are 22.2 units. The primary goal is to construct capital.

One piece of aerated concrete, measuring 625 by 300 by 250, weighs 28 kg, or 130 g. These kinds of wall panels are made at a density of D500. Among other places, the Kostroma plant produces them. In GOST 2007, the primary production standards are established.

Cold resistance level — F35.

Gas block 625X300X200 is suitable for masonry that is only one layer thick. This is not the use for smaller blocks. 30 kg is the gross indicator. Designs fit the bill:

• for houses;
• in country house construction;
• in garage construction.

The silicate 600å400å200 is not harmful. At times, it can withstand frost up to F75. This is how most Termocube products work. 30 kg in weight. B3.5 is the compressive strength.

The block 625å400Х250 is unique among the silicate building parts in the Ytong line. They follow the 2007-adopted GOST 31360 when producing it. One block can pull 800 g, or 43 kg. Conventionally, the product’s frost resistance is F100 and the material density is D500. And this is how the gas silicate block specific gravity by mass table (for grade D500) looks.

Dimensions, mm	Estimated dry weight, kg
600Х300Х100	15
250Х300Х600	36
600Х300Х200	21
100Х250Х600	10.5
600Х400Х250	14.4 (average)
600Х300Х250	22.5
625Х300Х250	28.13
600Х400Х200	thirty
625Х400Х250	43.8

However, nothing is as easy as it looks. The weight of a single unit of goods is not always the only consideration for builders and repairmen. Occasionally, the weight of a gas silicate cube holds greater significance for them. The truth is that when it comes to transportation and storage, they prioritize volume. Cubic meters are used to measure the capacity of trucks, wagons, individual storage spaces, and warehouses.

In order to find the mass of 1 m3, you must first figure out how many blocks fit into this particular value. Analyze the gas silicate element indicators measuring 25 x 40 x 62.5 cm. After multiplying each of these variables one after the other, we can observe that the outcome is 0.0625 m 3. Estimating that there should be 16 blocks per 1 m3 is not difficult at this point. If you know the weight of one copy, further computation is not difficult.

A pack of gas silicate that is 62.5 x 25 x 20 cm typically has 64 pieces of these products in it. However, the volume of the container is 2 m3, and this fact is crucial for accurate calculation during transportation. It is not hard to figure out the pack’s actual weight. All that needs to be considered is the final product’s volumetric weight.

Furthermore, it’s already included in the brand name after the letter D, so you don’t even need to know it.

When calculating the loads on a house’s foundation, you must know the weight of an aerated block because this will determine the foundation type and construction costs. The mass of the fillers and components determines the weight of a unit. The blocks are separated into 4 subgroups based on the criteria:

1. Very light porous – weighing ≈ 500 kg/m3;
2. Light blocks filled with expanded clay weighing ≈ 500–1800 kg/m3;
3. Heavy filled with gravel and crushed stone weighing ≈ 1800–2500 kg/m3;
4. Very heavy gas bricks weighing ≈ 2500-3000 kg/m3.

Large fraction aggregates carry the majority of the weight. The number of aerated concrete products in a pallet and 1 m3 is a crucial question because pallets make it easier to move heavy blocks around a warehouse or construction site.

A type of gas silicate

Blocks are often classified into multiple types based on their intended purpose.

• Wall. Stone is used for laying out external walls.
• Partition. Brick is used for mounting walls inside the object.

The dimensions of gas silicate blocks in conventional groups vary. When mounting partitions indoors, using smaller-sized products makes sense from a technical standpoint. This also saves money on investments, after all.

Gas silicate blocks are made in the following varieties based on their shape:

• rectangular, used for laying out load-bearing walls;
• tongue and groove – two protrusions are made on both sides, when connecting between the blocks, a cold bridge is not formed;
• U-shaped, used to make a reinforcing belt in the upper part of the walls and to erect a lintel.

Furthermore, producers create arbitrary-shaped blocks with unique grip handles.

The parameters, fillers, and shapes of concrete blocks vary. Concrete solutions, whether light or heavy, are used to make products.

When a building material’s dry mix density reaches 2500 kg/m3, it is classified as heavy. The two most common types of concrete blocks are cinder blocks and sand-cement mortar, both of which are composed of heavy concrete.

This kind is among the hollow products that have iron rod reinforcement. Because of the material’s great strength, one-story buildings are built using it. Using the M 100 brand of concrete products is preferable when building residential structures. There are two types of blocks produced:

• solid products are used for the construction of monolithic foundations;
• hollow elements are used for the construction of walls.

Lightweight concrete refers to building materials with a density of less than 1800 kg/cm3. Because of the lightweight component in the composition or the artificial foaming of the binder solution, the products weigh less. Aerated concrete blocks, foam concrete, and expanded clay concrete are examples of light products.

This material, which is created by adding cement, water, and expanded clay, is environmentally friendly. Expanded clay concrete’s primary characteristics are its air-passing structure and strong sound insulation. Additionally, building blocks have excellent thermal insulation properties.

Blocks are a kind of porous material; during the manufacturing process, aluminum powder, lime, and quartz sand are added to the mixture as a foaming agent for the cement composition. Both inside and outside, aerated concrete blocks have a cellular structure.

The foam block is made up of cement, water, sand, and a foaming agent. Both interior and exterior walls can be constructed with this material.

Aerated concrete blocks are a common option in contemporary construction because of their energy-efficient advantages and lightweight nature. With their many tiny air pockets, these blocks drastically lower the total weight without sacrificing strength or durability. This special feature helps reduce building energy costs and improve insulation while also simplifying transportation and installation. It is crucial for architects and builders to comprehend the weight of aerated concrete blocks if they want to maximize material and structural efficiency in their designs.

Weight of one pallet of foam block, foam concrete

One pallet of foam block holds approximately 1.5 m3, making it a relatively light material. A pallet of foam blocks weighs between 900 and 1200 kg, with a 1 m3 weighing between 600 and 800 kg.

Determining the specific gravity of aerated concrete by brand, density and size of aerated concrete block.

Thus, you must multiply the block’s volume (which was determined above) by its density and by the number of blocks in order to determine the weight of a cube of aerated concrete. The material’s brand indicates its density. Accordingly, a block bearing the D500 brand has a density of 500 kg/m3, while the D900 block has 900 kg/m3.

Going back to our example, let’s determine the weight of a single block. For instance, we can multiply 500 by the density of the D500 brand to obtain the weight of an aerated concrete block, which equals 31.25 kg. We now multiply the weight of 1 m3 of aerated concrete by 31.25×16 to obtain 500 kg.

Block Type	Weight per Block
Standard Aerated Concrete Block	20-30 kg
Lightweight Aerated Concrete Block	10-20 kg

Aerated concrete blocks, sometimes referred to as autoclaved aerated concrete (AAC) blocks, are widely used in construction because of their adaptability and low weight. These blocks have a distinctive structure and low density because they are made of a mixture of sand, lime, cement, water, and an expanding agent. Compared to conventional concrete blocks, this makes them simpler to handle and transport, which cuts down on labor expenses and construction time.

The insulating qualities of aerated concrete blocks are among their key benefits. Because of their excellent thermal insulation provided by their porous nature, they help to lower energy consumption and maintain comfortable indoor temperatures. Because of this feature, which improves building energy efficiency, they are an eco-friendly option.

Aerated concrete blocks are surprisingly strong and long-lasting for their light weight. They are appropriate for many different structural applications because of their substantial load bearing capacity. Their appeal is further enhanced by their ability to withstand fire and effectively insulate sound, providing comfort and safety in both residential and commercial buildings.

All things considered, aerated concrete blocks offer a useful and effective answer to contemporary building requirements. Their advantageous qualities in terms of strength, durability, insulation, and light weight make them an important building material. Builders can accomplish reduced construction times, more cost-effectiveness, and enhanced building performance by selecting aerated concrete blocks.
