Laying out the oven, every master must certainly remember that everything in this business matters, including the quality of the material, as well as the professionalism of the stove. If you want the furnace to have good traction, and the products in the base to retain and intensively give off heat, then you can’t neglect even the most insignificant nuances, here you should also include the choice of brick. Therefore, before creating a furnace, you need to figure out which material is better to choose, as well as what dimensions it has in order to make a calculation.
Description of stove brick
The kiln brick , the dimensions of which are mentioned in the article, can be fireplace or ceramic. In the latter case, we are talking about products for the manufacture of which red clay is used, such blocks are made using the firing technology. Among the advantages of this material is full compliance with state standards.
This brick can be used to erect the 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 types:
- quartz;
- basic;
- carbonaceous;
- fireclay refractory.
Description of species
Quartz is made from quartz chips, sandstone and some clay. The main ones are made of magnesite and lime mixture. If we are talking about carbon brick, then it is made using the technology of pressing graphite and coke chips.
The most common fireclay refractory brick today , clay acts as the basis of this material. When laying fireplaces and stoves, only fireclay and quartz bricks are used. Drawing a comparison between the first and the ceramic block, it can be noted that the stoves most often prefer chamotte products.
Reviews
The kiln brick, the dimensions of which are mentioned in the article, has many advantages and some disadvantages, which can be found out by reading the reviews. Among the pluses, consumers note the ability of the material to retain heat for a long time.
Heat transfer occurs slowly, which is explained by the long-term heat storage by the chamotte furnace. Users also note deficiencies, which are expressed in the ability to quickly collect and retain moisture within themselves over time. Therefore, fireclay is not recommended to be stored outdoors in the open.
Main characteristics
The kiln brick, the dimensions of which will be mentioned below, has two main characteristics that must be considered when choosing products. These include the frost resistance grade and the density grade. These features affect the quality of the unit. A density mark is not an indicator of low or high quality, but an indicator that allows you to get the following information: the higher the density is, the slower the brick will heat up.
A kiln brick, the weight of which any craftsman should be interested in, can have the following density indicators: from 100 to 500, intermediate values ​​are: 150, 200, and 250. You should not assume that the higher the density, the more suitable the material. A specific brick block parameter will be suitable for the construction of individual objects. If you need a brick for the furnace, then you should stop your choice on the density brand no more than M-250. If you prefer products with a higher density, the kindling of the furnace will be a real test.
Why pay attention to frost resistance
When choosing a material, it is important to consider not only the dimensions of the standard brick oven, which will be discussed below, but also the frost resistance brand, which allows you to get information about the ability to recover and absorb moisture.
This feature is important for products that will be used to equip the chimney. To carry out such work, you should choose a brick, which has quite impressive indicators of frost resistance.
Dimensions and Weight
On sale today you can find red stove bricks, which can have different sizes. For example, the parameters of a standard unit are limited by the following indicators: 250 x 120 x 65 mm. The end wedge 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, then it can have two sizes, 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 stove itself, a standard form should be preferred. Using the side wedge, you can form a curly masonry, while the end wedge is used for a narrower poke. It will be possible to block the furnace with the help of a stove.
The size of the stove brick may be different. Thus, the standard material is made a little longer, which allows you to use it, despite the impressive mass. Allocate another one and a half and double sizes of a standard brick. In the second case, we are talking about products whose length is twice as long as the length of a standard brick. If you are interested in the dimensions of the kiln red brick one and a half, then you should remember that its length is one and a half times longer than the length of a standard product.
Dimensions and characteristics of Vitebsk brick
For the reason that it is recommended to use exclusively high-quality material for masonry furnaces, which is well burned and can be processed, you should pay attention to the Vitebsk brick, which has sufficient strength.
In a wide assortment you can find several varieties of products from this manufacturer. For example, a ceramic kiln ordinary solid single brick, the dimensions of which are 250 x 120 x 65 mm, can have 85 or 200 strength grades. As regards 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 mass of one product is 3.7 kg.
The dimensions of Vitebsk stove bricks vary depending on the type of product. For example, a ceramic ordinary corpulent thickened 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 a block is manufactured in accordance with GOST 530-2012. On sale you can find ceramic ordinary solid brick with chamfers. Its dimensions remain the same as in the first of the mentioned cases, as well as mass, as well as thermal conductivity and water absorption. An ordinary full-bodied single profile brick weighs slightly less - 3.6 kg, but the thermal conductivity and water absorption remain the same, as well as the dimensions.
Chimney dimensions
When laying a chimney, it must be remembered that its vertical dimensions will have the greatest impact on traction. The correct chimney should not have a height of less than 5 m. Among other things, the difference in height between the roof surface and the tip is crucial. Thus, the top point of the pipe should be at the level of the ridge or slightly higher at a distance of no more than 3 m. If we are talking about a flat roof, then the elevation above it should be 1 m or more. When chimneys are equipped, brick dimensions must be considered. Thus, the wall thickness should be 10 cm, as for residential buildings.
The entire length of the brick must be laid out so that the area of ​​the inner part of the pipe is constant. The dimensions of the chimney also depend on the dimensions of the building. So, if the pipe is large, and you install it on a small house, then it will look comical. The smallest brick consumption can be achieved when the pipe has an internal dimension of 260 x 130 mm. This design will work if you lay out each row of 5 bricks.
You can meet pipes and more impressive sizes, this applies to Russian stoves with a large portal. In this case, it is recommended to choose a furnace brick, the dimensions of which will form a channel cross-section of 260 x 260 mm.
Conclusion
Chimneys can be laid from full-body ceramic bricks, the brand of which is designated as M-150, this is equivalent to stove bricks. It is necessary to use for this purpose a stove clay solution, filling the seams completely. The thickness of the latter should be 10 mm or less. When the pipe is laid in the attic and above the roof, cement must be added to the ingredients of the stove solution. Experts recently advised to use a facing brick for laying pipes over a roof, since it has high frost resistance.
