Brick sizes and markings. Marking of ceramic bricks Ceramic face brick one and a half 1.4 nf sizes

Table No. 2, GOST 530-2012 “Ceramic brick and stone” indicates all the main sizes of bricks by type -

"Brick" (designation of the type KR)

• 250 x 120 x 65 mm. (designation of product size - 1 NF)
• 250 x 85 x 65 mm. (product size designation - 0.7 NF)
• 250 x 60 x 65 mm. (product size designation - 0.5 NF)
• 288 x 138 x 65 mm. (product size designation - 1.3 NF)
• 288 x 138 x 88 mm. (product size designation - 1.8 NF)
• 250 x 120 x 55 mm. (product size designation - 0.8 NF)

"Brick with horizontal voids" (designation of the KRG type)

• 250 x 120 x 88 mm. (product size designation - 1.4 NF)
• 250 x 200 x 70 mm. (product size designation - 1.8 NF)

Facing bricks can have different shapes - chopped, smooth, etc. and sizes -

290x140x85 mm;

250x85x65 mm;

250x120x88 mm;

250x80x65 mm;

250x60x65 mm;

250x120x65 mm.

There are bricks with a wedge on the edge and with a wedge on the end. They are used for laying arched ceilings and gently turning wall corners. For example, the dimensions of such a brick of the Sh-22 brand are 230x114x65/55 mm, and the Sh-45 brand is 230x114x65/45 mm. The last, fractional parameter means taper - the numerator is the thickness of the brick at the beginning of the cone, the denominator is the thickness of the brick at the narrowed part.

The dimensions of shaped bricks are not regulated by GOST and can be very diverse. Their dimensions, rounding diameters and general shapes are reflected only in the manufacturer’s specifications (technical conditions). Also shaped brick It can also be exclusive, made to order.

What you especially need to pay attention to when choosing a brick:

. Single brick
Single brick is considered standard. Widely used for cladding cottages, building fences, etc. But single ordinary brick is rarely used. As a rule, it is full-bodied and hollow. Laying out partitions, load-bearing walls, ground floors Large bricks are preferred.
Single brick factories: Pochinkovsky, Losinoostrovsky, Vorotynsky, Markinsky, Zheleznogorsky, VVKZ, Mikhnevsky KZ, Engelssky KZ, Fokinsky plant

. One and a half brick
One-and-a-half bricks are mostly used as ordinary bricks and are used for the construction of partitions and load-bearing walls. As a facing brick, one-and-a-half (thickened) is used less often in private construction and more often in multi-story construction. This is due to the saving of mortar and the overall aesthetics of buildings.
One-and-a-half brick factories: Pochinkovsky, Losinoostrovsky, Vorotynsky, Markinsky, Zheleznogorsky, VVKZ, Mikhnevsky KZ, Mstera

. Bar
Bricks of this size are only gaining popularity. Block-sized facing bricks are often used in houses where materials that do not require additional insulation were used.
Factories for the production of brick blocks: LITOS, Zheleznogorsk conservatory

. EURO
Also the size of the facing brick is slightly thicker than a block, but in fact half of a single standard brick. We would like to draw your attention to the fact that the length -250 mm for all facing bricks is the same, and the height is different only for single - 65 mm and one and a half - 88 mm, the remaining dimensions change only in its thickness!
Factories producing EURO bricks: Zheleznogorsk conservatory, Wienerberger

. Double (Stone)
Until recently, one of the popular sizes of ordinary bricks for the construction of load-bearing walls of buildings and partitions. Also, a double stone can be porous, which is different high performance heat saving. With the advent of large format ceramic block, the use of double stone decreased.
Double Brick Plants: Mikhnevsky KZ, VVKZ, Sergo-Ivanovsky KZ

. 25th ceramic block (large format)
These are fairly new materials that are constantly gaining popularity. Used for the construction of high-tech and heat-saving buildings and cottages. Size 25 cm is its thickness. Suitable for creating interior walls, filling walls in monolithic high-rise buildings. It is also possible load-bearing walls, but they will require additional insulation.
Wienerberger, Braer, Gzhelsky KZ, KETRA

. 38th ceramic block (large format)
A large-format ceramic porous block of this size is used for the construction of load-bearing external walls that do not require additional insulation.
ATTENTION: It is necessary to use a special WARM SOLUTION for masonry.

CONCRETE

1. GENERAL CONCEPTS ABOUT CONCRETE

Concrete is an artificial stone obtained as a result of hardening of a rationally selected, mixed and compacted mixture of binder, fine and coarse aggregates, additives and water. Before hardening, the mixture is called a concrete mixture.

Currently, concrete with inorganic (mineral) binders is used for general construction work. To obtain a mixture and ensure hardening processes, such concrete is mixed with water.

There is usually no chemical interaction between the binder and the aggregate (except for autoclaved and silicate concrete), and therefore aggregates are also called inert materials.

Aggregates are added to concrete for technical and economic reasons. Without participating in chemical processes, at the same time, they significantly influence the structure and properties of concrete, create a rigid spatial frame that reduces shrinkage deformations. The use of cheap aggregates (compared to cement) makes it possible to reduce the cost of concrete, since aggregates and water make up 85–90%, and cement 10– 15% by weight of concrete.

To regulate the various properties of the concrete mixture and concrete, various additives are introduced into its composition that can give the mixture and concrete specific properties or improve their basic characteristics.

For civilians and industrial buildings and structures mainly have a number of requirements for concrete: high strength, frost resistance, reduced creep, for hydraulic structures (dams, locks, piers, bridge supports, etc.) operating in aquatic environments, increased density, water resistance, frost resistance, often chemical resistance . Massive structures require concrete with reduced heat generation and low shrinkage. Concrete used as heat and sound insulation materials must have low thermal conductivity and high closed porosity.

Despite all the variety of properties, concrete is a fragile material: its compressive strength is several times higher than its tensile strength, therefore, to absorb tensile forces, concrete is reinforced with metal and plastic rods (reinforcement).

The joint work of reinforcement and concrete is determined by good adhesion between them and similar rates of linear temperature expansion. At the same time, concrete protects steel reinforcement from corrosion.

Classifies CONCRETE according to the following criteria:

by appointment:

– structural (foundations, columns, beams, floor slabs, bridges and other types of structures);

– hydraulic engineering (dams, locks, canal linings, water supply and sewerage structures),

– structural and thermal insulation for enclosing structures (light);

– special purpose (heat-resistant, acid-resistant, for radiation protection, road, airfield, etc.);

type of binder: cement, silicate, gypsum, slag-alkaline, polymer concrete (plastic concrete), polymer cement, asphalt, etc.;

structure: dense, large-porous, porous, cellular;

type of aggregates: on dense rock aggregates, on porous aggregates.

By density:

– for especially heavy ones with a density of more than 2500 kg/m 3 ;

– heavy with a density of 2200–2500 kg/m3;

– lightweight with a density of 1800–2200 kg/m 3 ;

– light with a density of 500–1800 kg/m3;

– especially light with a density of less than 500 kg/m 3, used for thermal insulation.

according to hardening conditions:

– natural hardening (usually for monolithic structures);

– subjected to heat treatment at normal pressure (for the manufacture of prefabricated products and structures);

– autoclaved (mainly silicate and cellular).

Concrete technology includes a number of technological operations: preparation of raw materials, design and adjustment of concrete composition depending on design conditions and initial characteristics of raw materials, dosing of components concrete mixture, preparation of concrete mixture - mixing, production of reinforcing elements and installation in concrete (or formwork), transportation of the mixture to the place of installation, filling of forms or formwork and compaction of the mixture, subsequent hardening of concrete

It is not entirely true to say that only when we reach a certain age we are literally “covered by a wave of nostalgia” when we hear the melody of our youth or see some attributes of that time. Even a very small child begins to yearn for his favorite toy if someone took it away or hid it. We are all, to some extent, in love with old things, because they contain the spirit of an entire era. It is not enough for us to read about this in books or on the Internet. We want to have a real antique thing that we can touch and smell. Just remember your feelings when you picked up a Soviet-era book with slightly yellowed pages that emitted a sweetish aroma, especially when flipping through them, or when you looked at black and white photographs of your parents or grandparents, the same ones with an uneven white border. By the way, for many, such shots remain the most beloved to this day, despite the low quality of such images. The point here is not in the image, but in the feeling of spiritual warmth that fills us when they catch our eye.

If there are no “objects from the past” left in our lives due to endless moves and changes of place of residence, then you can buy antiques in our antique online store. Antique stores are especially popular now, because not everyone has the opportunity to visit such outlets, and they are concentrated mainly only in large cities.

Here you can buy antiques of various subjects.

To dot the i's, it should be said that antiques store is a special establishment that purchases, sells, exchanges, restores and examines antiques and provides a number of other services related to the sale of antiques.

Antiques are some old things that have a fairly high value. This could be: antique jewelry, equipment, coins, books, interior items, figurines, dishes, etc.

However, in a number of countries, different things are considered antiques: in Russia, the status of “antique thing” is given to an item that is more than 50 years old, and in the USA – items made before 1830. On the other hand, in each country, different antiques have different values. In China, antique porcelain is of greater value than in Russia or the USA.

In other words, when buying antiques It should be remembered that its price depends on the following characteristics: age, uniqueness of execution, manufacturing method (everyone knows that handmade valued much higher than mass production), historical, artistic or cultural value and other reasons.

Antiques store- quite a risky business. The point is not only in the laboriousness of searching for the required product and the long period of time during which the item will be sold, but also in the ability to distinguish a fake from the original.

In addition, a store selling antiques must meet a number of standards in order to gain the proper reputation in the market. If we are talking about an antique online store, then it should have a wide range of products presented. If an antiques store exists not only on the World Wide Web, then it must also be large enough so that the client can conveniently wander among the antiques, and, secondly, have beautiful interior and a pleasant atmosphere.

In addition, in our antique online store you can purchase Original gifts, furniture and kitchen utensils that can enliven the interior of your home and make it more sophisticated.

Antiques for sale in Russia, as in many European cities, such as Paris, London and Stockholm, has its own characteristics. First of all, these are the high costs of purchasing antiques, but the responsibility of a store selling antiques is also quite high, since these things represent a certain material, cultural and historical value.

When purchasing antiques in our store, you can be sure of the authenticity of the items you are purchasing.
