Which brick is it better to fold the stove and how to choose it?

When building a stove, selecting the proper kind of brick is essential to its longevity and effectiveness. Selecting the brick that best fits your needs can be overwhelming due to the abundance of options available in the market. We’ll examine the various kinds of bricks that are frequently used to build stoves in this guide, along with advice on how to choose wisely.

It’s crucial to realize that not all bricks are made equal, first and foremost. There are differences in the insulation, heat retention, and durability of different types of bricks. You should give priority to bricks for your stove that can endure high temperatures without breaking or deteriorating over time.

Refractory brick, sometimes referred to as firebrick, is a common material used in stove construction. Because of their unique ability to endure high temperatures, firebricks are the perfect material to line the interior of stoves and fireplaces. High-grade refractory materials, like clay and silica, which can tolerate temperatures as high as 1,800 degrees Fahrenheit, are used to make these bricks.

A less expensive alternative to firebrick that nevertheless has respectable heat retention qualities is clay brick. Even though clay bricks might not be as heat-resistant as firebricks, they can still be used to build the stove’s or fireplace’s exterior shell. It’s crucial to remember that clay bricks shouldn’t be used for the stove’s interior lining because high temperatures can cause them to crack or break.

It’s also important to take the size and shape of the bricks into account when selecting them for your stove. Bricks can be found in many different sizes and shapes, such as splits, arches, and standard bricks. Your stove’s design and dimensions will determine the size and form of the bricks you select. To ensure a tight seal and stop heat loss, it is crucial to choose bricks that fit together snugly.

Why is it important to choose the right brick?

The industry provides dozens of different types of clay-based bricks, which vary not only in color and size but also in subtle ways that are invisible to the unaided eye, such as:

  • density;
  • the presence of voids;
  • the ability to absorb water;
  • heat resistance;
  • scatter of geometric sizes within the same batch of bricks;
  • compression strength;
  • strength for a break;
  • Production quality.

The efficiency of using brick stone in the stove is impacted by each of these factors in one way or another. For instance, a material with a higher density can store more heat, but the resulting design will be heavier overall.

What bricks are the stoves from?

Let’s try to determine whether special bricks are needed and which brick is better to use for installing stoves and fireplaces both inside and outside the home. Every brick used in furnace construction and related projects needs to be in compliance with GOST 530–2012.

We have laid out a table with every kind of brick that is utilized for every kind of work in the perch.

Type/type of brick What is used for
Ceramic red is full -bodied Masonry of the foundation, the body of the furnace, heating shields, smoke pipes
Ceramic color is full -bodied Masonry of the outer part of the body of the furnace
Shamotnaya Masonry of the chamotum nucleus
Clinker Creation of wall thermal protection
Shamot bream Creation of the side walls of the chamotum nucleus, thermal protection of the first channel
Private, in order (single, half, quarter) The main material for laying internal and do not decorate the outer parts of the furnace
Checeful Designed for laying a more beautiful outer part of the furnace
Army Designed to close the rows of masonry from ordinary or shaped bricks, for example, an arch cast stone
Facial Designed for laying the most beautiful external part of the furnace

Main settings

The primary characteristics of these construction materials, which are used to lay heat-intensive furnaces, are as follows:

  1. Raw material.
  2. Geometric dimensions.
  3. Density.
  4. Moisture absorption.
  5. Compression and break strength (brand).
  6. Production quality.

Raw material

Different materials are used to make different types of bricks: ordinary ceramic, high-temperature clinker and chapatti, and special clay. The maximum temperature that a ceramic well can withstand is 700 degrees. Clinker and chamotum have temperature limits of 1100 and 1400 degrees, respectively.

Furthermore, the source material has an impact on the material’s capacity to absorb water.Ceramic brick leads this category, while clinker nearly never absorbs water.

Geometric dimensions

The geometric dimensions of Private brick are reported to be as follows, per GOST 530–2012:

  1. Length 250 mm.
  2. Width 120 mm.
  3. Thickness 65 mm.

The following sizes for chamotum brick, fire-controlled products, are specified by GOST 8691-2018:

  1. Length 230, 250, 300 or 345 mm.
  2. Width 114, 124 or 150 mm.
  3. Thickness 40, 65, 75 or 100 mm.

The heat-intensive design will last noticeably longer when the seams are made thinner, which is possible with smaller furnace-laying bricks.

GOST permits a 3–4 mm variation in the primary geometric parameters; however, we advise searching for materials that have the same.

Because its primary function is to line hot zones and because it cannot be repaired with the masonry of the furnace body, chamotis brick differs in size from other varieties of these building materials.

Because clinker has a very low water absorption capacity and is therefore not used as a furnace liner, its dimensions are in line with those of in-line bricks, even though it has an even higher heat resistance.

Apart from the conventional dimensions of face bricks, there exist abbreviated variants whose length deviates from the standard and is:

Additionally, they are known as:

  • three -quarter;
  • half;
  • quarter.

Density

Bricks have an average density of 1800 kg/m3, meaning that one product should weigh an average of 3.5 kg. Each element is obtained harder and thus stores more thermal energy when this parameter is higher.

It is preferable to decline the use of such material for installing a furnace in the home if the density surpasses 2000 kg/m 3 and each product weighs more than 3.9 kg. This is because the technology used in their manufacture is compromised.

After all, neither the precise composition of the mixture nor the behavior of such a building material when heated are known. Only the materials in the M300 and M500 classes are an exception, as their manufacturing process allows for a higher density.

Moisture absorption

This parameter is determined by submerging a dried brick in water for two days at 150 degrees in an autoclave, and then weighing it both before and after the dive.

10% is the ideal building material for the "stove" because it is tall enough and has a holistic structure while absorbing moisture sufficiently to create a stable connection with the pantry.

A brick is considered to have inadequate compression strength if its moisture absorption rate surpasses 16 percent. It is best not to use it for stove installation due to its excessively porous structure or deep cracks that could allow smoke to leak through.

Normal chamotal heat-resistant brick moisture absorption is 6%. It is preferable to decline using the parameter if it surpasses the 10% threshold.

Compression and break strength (brand)

The letter "M" denotes the strength of the compression and the break, and the numbers that follow it represent the pressure in KGS/cm^2, an excess of which causes the material to be destroyed. wherein the bending strength seldom surpasses 60 kgf/cm 2 and is substantially lower.

According to GOST 530–2012, the minimum acceptable brand of brick for laying a furnace is M250, and its strength for a bend of 35–40 kgf/cm 2 is more than sufficient for a furnace that is properly designed.

Bricks from brands lower than M250 are not suitable for laying furnaces because, although having enough strength for compression, their bending strength is unregulated, making them brittle even under light loads.

Furthermore, "fire requirements during the construction and operation of stoves and fireplaces" specify exactly this kind of requirement. However, a few stovers even use brick M200s, and these stoves have been operating trouble-free for decades.

Production quality

Perform the following actions to evaluate the brick’s quality:

  • Choose at random from the pallet of 5-10 bricks;
  • Inspect each of them, if at least one there are black spots or deep cracks, then the manufacturing technology is disturbed and it is better to refuse the purchase;
  • If the bricks are at least slightly different, then the material from different parties is made in one pallet, so it is better to refrain from buying;
  • measure each brick if the deviation in width and thickness exceeds 3 mm, in length 4 mm, perpendicularity and flatness of surfaces of 3 mm, then such brick will have to be placed on a thick layer of solution, which is not always acceptable;
  • On the front brick of at least three adjacent sides (spoon, dump and bed) should not have any defects, otherwise it is better to refuse the purchase;
  • Take the brick in the hand and tap it with any metal object, for example, the key from the car, it must make a clear sonorous sound, if the sound is deaf, it is better to refrain from buying;
  • weigh each selected brick, if the weight of at least one differs more than 5%, it is better to refuse the purchase.

Is there a real "stove" brick?

Bricks for construction and stoves were produced by the Russian industry during the Empire’s era, but the USSR had already stopped producing genuine "stove" bricks since they needed to be more durable and fireproof.

Consequently, after reading that the modern brick described himself as "stove," you realize that this is just a marketing ploy. In actuality, though, this is an average building material that might meet GOST requirements.

Because of this, professional stoves prefer to use material that was taken from furnaces in the middle of the 19th and early 20th centuries, if given the chance.

The best manufacturers

To assist you in deciding which brick manufacturer is best to select for the furnace’s construction, we have prepared a table that includes brick manufacturers who have received positive feedback from users on forums or websites:

Price

We set up a table with bricks from reputable manufacturers—which we discussed earlier—as well as those that are available in stores but whose manufacturing facilities aren’t always open.

After deciding which brick to use for your stove, in addition to red or another color and other factors, you also need to consider which material is more cost-effective.

The name of the manufacturer Description of brick Price by one, rubles

Additional expenses

If you have already made the decision to purchase a brick to be used in the furnace’s construction, you will incur additional costs as this building material needs to be transported to the site of the project and immediately unloaded. As a result, the carrier’s and the loader’s services will cost you money.

You can hire small trucks with a 3–4 ton crane with a lifting capacity of 3–4 tons to transport small parties (400–800 pieces) over short distances (within a city or district).

You will need to use a tractor with a semi-trailer to transport building materials from another area, and then you will need to hire a crane to unload the pallets.

Since all of this is costly, it is typically more advantageous to purchase cheaper and more accessible building supplies if a highly artistic stove is not necessary.

After all, even though their prices differ greatly, the corresponding GOST and having the same class of strength and roughly equal brick manufacturing quality have no advantages over one another.

Additionally, consider the possibility that the pallet may contain damaged bricks, which are simple to return and replace with new ones if the manufacturer is in the area. That being said, replacing them will be a costly and gloomy process if you have to move it to a different area.

What parameters can be neglected?

The primary factor that can be disregarded is aesthetic appeal. An angle grinding machine, when used to carefully sharpen even a high-quality ordinary brick, can make it appear no less beautiful than its comparatively more expensive counterparts while also saving money.

Some stoves and customers use building materials with the strength of M100 – M200, but they do so at their own risk, in defiance of the M250 requirement. More often than not, there won’t be any unfavorable effects from this decision, but in an emergency, selecting less dense building materials could serve as the foundation for filing an administrative or criminal complaint.

Choosing the right brick for building a stove is crucial for efficient heating and insulation in your home. The type of brick you select can significantly impact the performance and longevity of your stove. When considering which brick to use, factors like thermal conductivity, durability, and cost come into play. Fire clay bricks are a popular choice due to their high heat resistance and ability to withstand extreme temperatures, making them ideal for constructing stoves. Additionally, insulating firebricks provide excellent heat retention, helping to maximize the stove"s efficiency. It"s essential to assess your specific needs and budget when selecting bricks for your stove, ensuring you achieve optimal heating and insulation for your home.

What will happen if you use the inappropriate material?

Ordinary full-bodied red brick is the only material that can be used to lay the furnace’s body; rarely, the front and chamotis products are used to line the furnace. Videos of stoves made from hollow or chamotis bricks occasionally surface on YouTube, but none of the creators of these materials explain what became of their creation after five to ten years.

Deeply cracked materials are frequently used in the construction of the most inexpensive "Swedes." What’s more, the cracks are placed not only inside, where they won’t cause smoke leaks or air suction, but even outside, where they will create a wall of chimneys.

Such economy results in a significant increase in the risk associated with using this stove, particularly if it is not completely hubby or is not covered by a casing.

The brick shrinks as it heats up, growing only on the side that is being heated. This causes an internal voltage to develop in the brick, which increases the likelihood that it will crack and let smoke and air out.

A critical difference in KTR between it and the solution pantry appears as a result of the same process occurring in hollow bricks, but because of their smaller mass and density, they heat up much faster. As a result, their linear dimensions increase more, which is in line with building materials.

When the chamotte body of the furnace is built on mercantis rather than the standard masonry solution, the masonry and seams have the same coefficient of thermal expansion, preventing destruction. However, it is difficult to make the same trustworthy masonry from it as from a red ordinary analogue due to the weak absorption of moisture.

Even with well-organized firewood, the structure will be rapidly destroyed by different KTR if the goal is to create a color pattern in one masonry, in order, and with chamotis material. The same thing occurs when silicate and ceramic bricks are laid together.

How to choose the right one?

Do the following to select the appropriate material for laying any kind of furnace:

  1. Determine the number of materials of each type (in order, shag. D.).
  2. Collect maximum offers for the sale of brick in your city, area or even region.
  3. Carefully study forums where they discuss the quality of a brick, look for coincidences with the material available in your region.
  4. Select the most interesting and adequate offers, then go to sellers or manufacturers to inspect the material live.
  5. Make sure high quality building materials.
  6. If possible, find the coordinates of those who have already bought the brick of this seller or manufacturer, then contact the buyers and ask them to evaluate these products.
  7. Calculate the costs of buying and delivery of building materials from different sellers or manufacturers.
  8. Remember that if the building materials you need is not burned, it rings when hit with a metal object and does not have strong deviations of geometry or size, then it is suitable for the construction of the furnace, so focus either on the appearance or the total cost, depending on the fact that It is more important for you.
  9. Before buying, be sure to request a brick documentation from the seller or manufacturer, in which all its characteristics will be spelled out, including permissible forms of shape and size. But even if you could not get such a document, focus on the corresponding GOST and, having discovered marriage in laying, return it and demand a replacement or refund of money. This is your right in accordance with Russian law.

Useful videos on the topic

The following video explains which bricks are used around stoves in homes, which brand is best for use in wood structures, and how to select facing material:

Another educational video explaining what kind of material is used to install the stove in the house, what kind of brick is required, what it’s called, and which construction method is best:

Brick Type Considerations
Firebrick Best for high-temperature applications like stove construction. Choose dense and durable varieties.
Refractory Brick Similar to firebrick but more resistant to heat and thermal shock. Ideal for areas subjected to intense heat.

When choosing the appropriate brick to build a stove, there are a few things to take into account. The brick’s resistance to heat is the most important factor. Because clay bricks don’t break or distort when exposed to high temperatures, they are frequently used. Firebrick is an additional great choice; it is made especially for high-heat applications. These bricks are perfect for stoves because they are dense and have low thermal conductivity.

The brick’s porosity is another important factor. Bricks with lower porosity are better because they don’t absorb as much moisture and don’t break or crack when exposed to heat. Because firebrick usually has a low porosity, the stove will last a long time.

Additionally, the construction of the stove is influenced by the size and shape of the brick. Bricks of standard size are useful for construction, but certain designs or spaces may require bricks of a specific shape. To build a sturdy and attractive structure, make sure all of the bricks are the same size.

Finally, think about the brick’s price and availability. Although firebrick is typically more expensive than clay brick, its increased durability and resistance to heat make the purchase worthwhile. Clay bricks, on the other hand, can still be a good choice if money is tight and they are carefully selected due to their heat-resistant qualities.

In conclusion, give heat resistance, low porosity, uniformity, and affordability top priority when selecting bricks for constructing a stove. Choosing the appropriate materials is crucial to building a safe, effective, and long-lasting stove to heat your house, whether you choose to use firebrick or clay bricks.
