Furnace brick: sizes, characteristics, description and reviews

Spreading the oven, each master mustremember that everything in this matter matters, including the quality of the material, as well as the professionalism of the stove-maker. If you want the furnace to have a good draft, and the products in the base are kept and give heat intensely, then you can not neglect even the most minor nuances, here you should also include the choice of brick. Therefore, before creating a furnace, it is necessary to understand what material is better to choose, as well as what dimensions it has to make the calculation.

Description of oven bricks

Brick oven, the dimensions of which are mentioned inarticle, can be a fireplace or ceramic. In the latter case, we are talking about products for the production of which red clay is used, such blocks are made using the technology of roasting. Among the advantages of this material is full compliance with state standards.

This brick can be used for erectionthe upper part of the chimney, where the furnace heat will not be so intense. If you are interested in fireplace bricks, then you should know that they are divided into 4 more types:

• quartz;
• basic;
• carbon;
• refractory chamotte.

Description of Species

Quartz is made of quartz chips,sandstone and some clay. The main ones are made of magnesite and lime mixture. If it is a carbon brick, it is made using the technology of pressing graphite and coke crumb.

The most common today is fireclayRefractory brick, clay is the basis of this material. When laying fireplaces and stoves, only chamotte and quartz bricks are used. Making a comparison between the first and the ceramic block, it can be noted that the stoves most often prefer chamotte products.

Reviews

Brick oven, the dimensions of which are mentioned inarticle, has many advantages and some shortcomings, which you can learn by reading the reviews. Among the pluses, consumers note the ability of the material to hold heat for a long time.

Heat transfer occurs slowly, which explainslong-term preservation of the heat of the fireclay stove. Users also note the shortcomings, which are expressed in the ability to quickly gain and retain moisture within a long time. Therefore, chamotte is not recommended for outdoor storage in the open air.

Main characteristics

Brick oven, the dimensions of which will be mentionedbelow, has two main characteristics that must be taken into account when selecting products. These include the brand of frost resistance and the brand in terms of density. These features affect the quality of the unit. Mark by density is not an indicator of low or high quality, but an indicator that allows you to get the following information: the higher the density appears, the slower the brick will heat up.

Oven bricks, weight, the dimensions of which mustto interest any master, can have the following density indicators: from 100 to 500, as intermediate values ​​are 150, 200 and 250. Do not assume that the higher the density, the more suitable material. A certain parameter of the brick block will be suitable for erecting individual objects. If you need a brick for the oven, then you should stop your choice on the density mark no more than the M-250. If we prefer products with a higher density, the kindling of the furnace will prove to be a real test.

Why pay attention to frost resistance

When choosing a material, it is important to take into account not onlythe dimensions of the stove brick standard, which will be discussed below, but also the brand of frost resistance, which provides information on the ability to recoil and absorb moisture.

This characteristic is important for products that arewill be used for furnishing the chimney. To conduct such work should be selected brick, which has a fairly impressive indicators of frost resistance.

Dimensions and weight

On sale today you can find a red stoveBrick, which can have different sizes. For example, the parameters of the standard block are limited to the following parameters: 250 x 120 x 65 mm. Wedge end has the same parameters as the side wedge, which, in turn, has the following dimensions: 230 x 114 x 65 x 55 mm.

If you prefer a plate, it can have twosize, among them: 460 x 230 x 75 or 600 x 230 x 90 mm. When choosing the size of the kiln brick for the chimney and the furnace itself, the standard form should be preferred. With the help of the side wedge, it is possible to form a figured masonry, while the end piece is used for a narrowed-in point. You can close the furnace by using a stove.

The size of the kiln brick can be different. Thus, the standard material is made a little longer, which makes it possible to use it, despite the impressive mass. There are still one and a half and double the size of a standard brick. In the second case, we are talking about products whose length is more than two times the length of the standard brick. If you are interested in the dimensions of a red brick one-and-a-half brick, you should remember that its length is one and a half times larger than the length of the standard product.

Dimensions and characteristics of Vitebsk brick

For the reason that for masonry furnacesit is recommended to use only high-quality material, which is well burned and treatable, it is necessary to pay attention to Vitebsk brick, which has sufficient strength.

In a wide range you can findseveral varieties of products of this manufacturer. For example, a ceramic stove of ordinary solid brick with dimensions of 250 x 120 x 65 mm, can have strengths of 85 or 200. With regard to frost resistance, the material can refer to F15, F25 or F35. The water absorption of this material is 8%, and the thermal conductivity varies within 0.529 W / (m · K). The weight of one product is 3.7 kg.

The dimensions of Vitebsk brick bricks vary independing on the type of product. For example, a ceramic ordinary full-bodied thick brick will have the following dimensions: 250 x 120 x 88 mm. Its water absorption varies from 13 to 14%. The weight reaches 4.8 kg, and the unit is manufactured according to GOST 530-2012. On sale you can find a ceramic solid brick with chamfers. Its dimensions remain the same as in the first of these cases, like the mass, as well as the thermal conductivity and water absorption. Several weighs less ordinary full-bodied profile single brick - 3.6 kg, but the heat conductivity and water absorption remains the same as the dimensions.

Dimensions of the chimney

When laying a chimney,that its vertical dimensions will have the greatest impact on traction. The correct chimney must not have a height of less than 5 m. Among other things, the difference in height between the roof surface and the headpiece is crucial. Thus, the upper point of the pipe should be at the level of the ridge or be slightly higher with a distance of no more than 3 m. If it is a flat roof, then the elevation above it should be 1 m or more. When the chimneys are equipped, the brick dimensions must be taken into account. Thus, the thickness of the walls should be 10 cm, as for residential buildings.

Over the entire length of the brick must be laid out soso that the area of ​​the inner part of the pipe is constant. The dimensions of the chimney depend also on the dimensions of the building. So, if the pipe is big, and you install it on a small house, then it will look comical. The lowest consumption of bricks can be achieved when the pipe has internal dimensions of 260 x 130 mm. Such a design will be obtained if you lay out each row of 5 bricks.

You can find pipes and more impressivedimensions, this applies to Russian furnaces with a large portal. In this case, it is recommended to choose a kiln brick, the dimensions of which allow to form a channel section of 260 x 260 mm.

Conclusion

Pipes can be stacked from the full bodyceramic brick, the brand of which is designated as M-150, it is equated with kiln brick. Use for this you need a clay oven solution, filling the seams completely. The thickness of the latter should be 10 mm or less. When the pipe is laid in the loft area and above the roof, cement must be added to the ingredients of the mortar. Specialists recently advised to use for laying pipes over the roof facing brick, since it has high frost resistance.
