When laying out the stove, every master must certainly remember 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 stove to have good traction, and the products at the base retain and intensively give off heat, then even the most insignificant nuances cannot be neglected, and the choice of brick should also be included here. Therefore, before creating a furnace, it is necessary to figure out which material is better to choose, as well as what dimensions it has in order to make a calculation.
Description of oven bricks
Stove 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 build the top of a chimney where the stove heat will not be as intense. If you are interested in fireplace bricks, then you should know that they are further divided into 4 types:
- quartz;
- main;
- carbon;
- refractory fireclay.
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 is the basis of this material. When laying fireplaces and stoves, only fireclay and quartz bricks are used. Making a comparison between the first and the ceramic block, it can be noted that stove-makers most often prefer fireclay products.
Reviews
Kiln brick, the dimensions of which are mentioned in the article, has many advantages and some disadvantages, which you can learn about by reading the reviews. Among the advantages, consumers note the ability of the material to retain heat for a long time.
Heat transfer is slow, which is explained by the long-term preservation of heat by the fireclay furnace. Users also note disadvantages, which are expressed in the ability to quickly gain and retain moisture inside themselves for a long time. Therefore, fireclay is not recommended to be stored outdoors in the open air.
Key Features
Stove brick, the dimensions of which will be mentioned below, has two main characteristics that must be considered when choosing products. These include a frost resistance grade and a density grade. These features affect the quality of the block. The density grade is not an indicator of low or high quality, but an indicator that allows you to get the following information: the higher the density, the slower the brick will heat up.
Kiln brick, the weight of which should be of interest to any master, 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 material. A certain parameter of a brick block will be suitable for the construction of individual objects. If you need a brick for the oven, then you should opt for a density grade no more than M-250. If you prefer products with a higher density, then lighting the oven will be a real challenge.
Why pay attention to frost resistance
When choosing a material, it is important to take into account not only the dimensions of the standard oven brick, which will be discussed below, but also the frost resistance grade, which allows you to obtain information about the ability to return and absorb moisture.
This characteristic is important for products that will be used to equip the chimney. To carry out such work, you should choose a brick that has quiteimpressive frost resistance.
Dimensions and weights
On sale today you can find red stove bricks, which can have different sizes. For example, the parameters of the standard block are limited to 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 stove brick for the chimney and the stove itself, a standard shape should be preferred. With the help of a side wedge, it is possible to form curly masonry, while the end wedge is used for a narrowed poke. It will be possible to block the firebox with the help of a stove.
Kiln brick size may vary. Thus, the standard material is made a little longer, which allows it to be used despite its impressive mass. There are also 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 a one-and-a-half red oven brick, 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 bricks
For the reason that it is recommended to use exclusively high-quality material for laying stoves, which is goodfired and processed, you should pay attention to the Vitebsk brick, which has sufficient strength.
In a wide range you can find several varieties of products from this manufacturer. For example, a ceramic furnace ordinary solid single brick, whose dimensions are 250 x 120 x 65 mm, may have a strength grade of 85 or 200. As for frost resistance, the material may 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 kiln bricks vary depending on the type of product. For example, a ceramic ordinary solid thickened brick will have the following dimensions: 250 x 120 x 88 mm. Its water absorption varies from 13 to 14%. The mass reaches 4.8 kg, and the block is manufactured in accordance with GOST 530-2012. On sale you can find a 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 solid profile single brick weighs somewhat less - 3.6 kg, but the thermal conductivity and water absorption remain the same, as do the dimensions.
chimney dimensions
When laying a chimney, remember that its vertical dimensions will have the greatest impact on draft. A correct chimney should not have a height of less than 5 m. Among other things, the height difference between the roof surface and the head is of decisive importance. SoThus, the top 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 from it. If we are talking about a flat roof, then the elevation above it should be 1 m or more. When chimneys are being equipped, brick dimensions must be taken into account. Thus, the thickness of the walls should be 10 cm, as for residential buildings.
The brick must be laid out along the entire length in such a way that the area of \u200b\u200bthe inside 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 lowest consumption of bricks 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 of more impressive sizes, this applies to Russian stoves with a large portal. In this case, it is recommended to choose a stove brick, the dimensions of which will allow forming a channel section of 260 x 260 mm.
Conclusion
Chimneys can be laid from full-bodied ceramic bricks, the brand of which is designated as M-150, this is equated to oven bricks. For this, it is necessary to use an oven clay mortar, filling the seams completely. The thickness of the latter should be 10 mm or less. When the pipe is laid in the attic area and above the roof, cement must be added to the ingredients of the furnace mortar. Experts have recently advised using facing bricks for laying pipes above the roof, as ithas high frost resistance.
