Red brick size (standard)
One of the most common building materials is brick. Many generations of bricklayers used it as blocks to build a wide variety of buildings. The principle of technology has not changed over the centuries, but has only been improved due to technical developments. Its size also differed by different standards, but did not tolerate the global changes in its projections.
Brick was one of the oldest building materials. It was widely used and played an important role in the construction of Mesopotamia, Ancient Egypt and Ancient Rome. At that time, many complex structures were built from bricks of 45 x 30 x 10 cm in size, including arches, arches, etc. In different countries of Europe in the times after the Middle Ages the sizes of bricks differed significantly. For example, English brick with parameters 9 x 4.5 x 2.5 (in inches) was considered a standard-size brick in 19th century England. In Germany, a red brick size of 25 x 12 x 6.3 (in centimeters) was ratified at the state level.The smallest size of all were American bricks (21 x 10 x 5.3 cm).
The Russian red brick is standard, the dimensions of which were 6 x 3 x 1.5 inches, were larger than English and German. Its weight fluctuated around 3-4 kilograms, depending on its parameters. Such brick sizes were based on those used by Fioravanti in the construction of the Kremlin. But as far from large cities away, the standardization of brick dimensions was lost, and they were made in accordance with the wishes of customers.
Technical progress played a role, and a single all-Union size of red brick was proposed for introduction into the USSR during the period of global development. As a result, in 1927, a standard was approved of 250 x 120 x 655 millimeters and a weight of no more than 4.3 kg.
There are two types of bricks: white and red, their differences are due to the different materials used in their manufacture. Red brick is obtained in the process of burning briquettes with previously cleaned and crushed clay mixture.
The pledge of quality bricks
A distinctive feature of high-quality red brick is a clear and sonorous sound made by it upon impact.Its quality is manifested in the structural strength and durability. When laying the walls should not be used perezhzhenny brick. It can be distinguished by its characteristic burned black color, fused edges and slight bending of the form. It is suitable only as a material for laying the foundation.
Types of bricks
There are standard sizes of red bricks that do not depend on the technology of its manufacture. Such material, without doubt, is the most practical, reliable and easily accessible resource for construction. The size of the red brick is determined by the aspect ratio of 1: 1/2: 1/4. Such dimensions determine the excellent strength of the structure. And in addition, 8 bricks with such dimensions and mortar form the correct cube.
Nowadays, red brick is widely used in Russia as a standard, the dimensions of which are 250 x 120 x 65 mm and the weight is 3.5 kilograms. There are also excellent models of bricks:
- Modular - 288 x 138 x 65 mm.
- One and a half - 250 x 120 x 88 mm.
- Euro - 250 x 88 x 65 mm.
- Double - 250 x 120 x 138 mm.
The most common is still the usual single red brick, which appeared in the USSR in the 30s of the twentieth century, the dimensions of which are ideal for alternating vertical spoon and vertical knotted rows.Bastard has internal voids to reduce weight and increase thermal insulation characteristics due to closed air pores. As well as the half-double, double brick has voids, and therefore it is used for laying lightweight walls. The choice of bricks for building a particular structure depends on the functional purpose and technical qualities that it must possess.
It should also be said that a different size of red brick is used for the facial finish. Standard facing material has the following dimensions: 250 x 120 x 65 mm. A half-and-a-half has a size of 250 x 120 x 88 mm, and a double one - 250 x 130 x 120 mm.
In addition to markings related to dimensions, there is also a mark that determines the strength of a material under compressive pressure, it is in the range from 75 to 300 units. The greater the value, the greater the compressive force that the brick can withstand.
Approved in Russia GOST brick sizes
In accordance with GOST 530-2007, a single size of red brick is installed. The standard requires deviations of no more than 5 millimeters from such necessary characteristics: the edge parallel to the base of the masonry is 250 x 120 mm; part,large in size among perpendicular bed, spoons - 255 x 65 mm; the smaller part and also perpendicular to the bed, a jab - 120 x 65 mm.
European brick size standards
By European standards, the size of the red brick is also different. The most common in Europe are bricks with NF markings (normal, size - 240 x 115 x 71 mm) and DF (thin, size - 240 x 115 x 52 mm). As you can see, they are somewhat smaller than the Russian ones, and the usual size of a solid red brick in the European marking is under the symbol of the Russian Federation. The classic choice of Europeans for laying walls is red brick, whose dimensions correspond to the DF marking. In contrast to it, the Russian Federation requires lower costs for mortar, and construction with this type of brick proceeds faster. There are also decorative materials with a perfectly smooth surface and precise dimensions. The layer of such bricks does not need further finishing, but during the laying it is necessary to separate the seams. This type of material in modern construction is becoming increasingly popular in the light of the latest fashion trends.
The so-called "warm ceramics", that is, stones and blocks of large format, gradually gaining increasing popularity with respect to standard red brick.The reason for this was technical progress. Previously, technical conditions did not allow the burning of large volumes of clay, and therefore the size of the red brick remained small, but now with the latest equipment it is possible to produce large and durable blocks that have a small mass. Such materials are a serious competition to the usual red brick, but, despite all these facts, it is very well entrenched in the market of building materials, and soon oblivion does not threaten him.
