The dimensions of one and a half brick, single and double: their features

Despite all the variety available on the market of building materials, is still deservedly popular and professional builders, and fans enjoyed a brick. This robust, durable and versatile material has several standard sizes. The greatest demand in the construction and decoration of buildings there on the brick size of one and a half, which is a significant savings during its use and aesthetics.

The size of a single brick, One and a half and double

When calculating the amount of material necessary to consider what size of a brick, which will be needed during construction. This will help to avoid unnecessary costs.

There are 3 basic sizes:

• single (single row, standard);
• sesquihydrate (thickened);
• double (second name - double stone).

single brick Parameters are as follows: length - 250 mm Width - 120 mm, the height - 65 mm.

Sesquihydrate brick dimensions: width - 250 mm Width - 120 mm, the height - 88 mm. Dimensions of double brick, as well as thickened, differ only in height - 138 mm. Currently commercially represented bricks and non-standard sizes - "Euro" (length 250 mm, width 85 mm, height 65 mm) and the module at the same height having a length of 288 mm and a width of 138 mm.

Benefits one and a half brick in comparison with single

Calculations show that the material consumption per 1 m³ of mortar joints in view of 394 units. the application of a single brick and 302 units. when applying sesquihydrate. This enables good savings during construction.

So, during the laying of the supporting structure can be used not standard 3 rows of bricks and number facingAnd 2 rows of hollow bricks and facing a series of one and a half. Moreover, substantial savings not only the amount of material used, but also the flow of the solution.

The height of one and a half brick is greater than the height of a single only 23 mm, but this difference allows up to 30% to accelerate the masonry works. The apparent advantage of thickened brick is its weight. Thus, single brick weighs from 2 to 2.3 kg, and the weight of one and a half brick, in spite of the large size, weighs only a third more.

The main types of brick thickened by materials designed and the type

There are several classifications of conventional bricks. First of all, depending on the material from which it is produced is isolated:

• ceramic, or red;
• silicate, or white.

These two types have different characteristics at, areas of application and the properties of the same size. Dimensions sesquihydrate silica brick and ceramic sesquihydrate - 250 mm, 120 mm and 88 mm

Ceramic brick: the technology of production, the advantages and disadvantages

Bastard produce ceramic bricks from clay without impurities (sulfate, marl) and special additives imparting desired properties to the finished product.

It is interesting!Raw materials from which produced red brick, is not suitable for the manufacture of any other product made of clay.

Methods of making bricks:

1. Plastic. The clay feedstock with high humidity (30%) come from the belt press, and drying is calcined at a temperature of about 1000 ° C. It is very important that you sustain the burning time. And unburnt and burnt through brick are not only unaesthetic appearance, but also low quality. If unburnt brick has a very light color and low rates of water and frost, when OFA - characteristic markings, numerous cracks and uneven shape, and the high level thermal conductivity. Ideally, after proper heat-treatment the surface becomes semi-matt ceramic bricks and on impact it produces a characteristic ringing sound.
2. dry pressing method. With this method, the brick is formed of raw clay with low humidity level (10%) under a strong pressing. The resulting finished product must not be used for the construction of premises with high humidity.

The advantages of ceramic bricks:

• excellent sound insulation;
• It is made from environmentally friendly material - clay, it is absolutely harmless to health in the process of construction and during operation;
• versatility (suitable for building and residential and industrial buildings, for the construction of internal and external walls);
• resistance to adverse weather conditions, including heavy frosts;
• durability;
• strength;
• large variety of shapes, sizes and colors (mixing different varieties of clay, manufacturers achieve a rich color palette - red, brown, beige, terracotta, yellow, peach color, which allows the use of ceramic bricks in the construction of both new buildings and in restoration papers);
• good heat and steam;
• material easily deformed during transportation, and at its edges chipped;
• moisture resistance.

Disadvantages red brick:

• whitish appearance salt plaque;
• high price.

Sand-lime brick: how it is made, the pros and cons

In its manufacture used 9 parts of purified from impurities and manganese clay quartz sand and 1 part lime. From this the lime-sand mass is formed by dry-pressing the bricks, and then for 10-13 hours expose them to water vapor and high pressure.

In order to give the finished product the desired shade in the silicate mass is added special resistant to adverse weather conditions pigments. This makes it possible to achieve a huge variety of colors - even those not typical for the traditional buildings made of brick, like blue, blue, yellow, pink, purple.

Advantages of one and a half sand-lime brick:

• good sound insulation and low thermal conductivity;
• environmental friendliness;
• durability;
• strength;
• frost;
• resistance to adverse weather conditions;
• reasonable price (about a third lower than the cost of red bricks);
• precise geometry of the finished product;
• a huge selection of colors and textures.

Disadvantages of the material:

• lack of moisture (can not be used when laying the foundations, manholes, basements, cellars - all objects of a zero cycle, where there is a risk of flooding or constant contact with ground water);

• low heat resistance;
• considerable weight (weight of silica brick sesquihydrate corpulent ranges from 4.2 to 5 kg, and the same ceramic - from 4 to 4.2 kg).

It is important! Due to the low cost of private homes in the construction of chimneys, fireplaces and stoves are often used lime bricks. However, their service life will be of short duration - only a few years, and under the influence of high temperatures will begin to crumble masonry. So in reality, such savings comes very costly and is unsafe.

Types of bricks in scope

distinguished:

• building brick (other names - the rough, ordinary, masonry, ground);
• front (face, front);
• special.

Rough brick used in the construction of interior partitions, walling, self-supporting and load-bearing walls, as well as to fill the voids. It can be used in the construction of exterior walls, but only with the mandatory application of the plaster.

Facing bonder brick used for interior decoration and facades. A superb appearance - straight edge without chipping and cracking, clear geometric line. This is one of the most affordable finishing materials. It is worth remembering that the red brick is suitable for areas with high humidity and hot arid regions of the best choice would be sand-lime brick.

Important! Besides standard size bricks facing sesquihydrate and is commercially available single bricks with a width of 85 mm, 80 mm and 60 mm at a length of 250 mm, and with dimensions of 290 mm, 140 mm and 85 mm.

Additionally isolated textured (ham it has a decorative surface as an untreated stone, smooth or rough edge) and shaped bricks (it has a complex shape, rounded edges, they decorate the window sills, window frames, corners of buildings).

Special brick - notably refractory firebricks. He is not afraid of repeated exposure to high temperatures and retains heat well. Bonder refractory bricks - this is the best, durable and safe choice for laying the inner surfaces of fireplaces, stoves and chimneys.

Types sesquihydrate brick depending on the design type

The bricks are solid and hollow. These bricks are clearly different in scope. The first is always used in the construction of load-bearing structures, in the construction of fireplaces and chimneys, the second during the construction of partition walls and cladding buildings.

The brick porosity should not exceed 13% (for silicate bricks), or voids must be absent. In the case of hollow silicate brick number reaches 30% of voids in the clay bricks may be 15% lower rate. Moreover, in the ceramic holes have different shapes and are uniformly distributed over the entire area, while the silicate are shifted to the center and, as a rule, have the shape of a cylinder.

What gives these cameras? They essentially save raw material consumption, time spent on its production, hence reducing the cost of finished products. Significantly reduced the weight of the product and the whole construction in general, and the load on the foundation. For example, weight sesquihydrate hollow bricks from clay is 3-3.2 kg, and weight corpulent red 4-4.2 kg. For comparison, the weight of bricks one and a half white - 5 kg for the full-bodied design and 3.9 kg in the hollow.

The most important advantages of a hollow one and a half brick applies excellent heat-insulating characteristics, which can further save on the thickness of the walls.

Durability, weight and one and a half size bricks

The most important characteristic of a construction material is its ability to resist different loads and not deformed.

Optimum strength bricks possess marked. They can be used in the construction of country houses, and in the construction of multi-storey buildings, with Footing, fireplace or stove, bearing walls and partitions, and cladding for internal works. Last but not least this is due to release a variety of shapes of bricks of the brand. He is an ordinary rectangular, trapezoidal and shaped.

He has good fire resistance, high density, due to a worse absorbs moisture and durability. Dimensions brick M150 are the same as that of the material with lower strength values: single, thickened, the euro.

Mass M 150 solid bricks single reaches 3.6 kg (an average of 2 to 2.2 kg), sesquihydrate - 4.5 kg (average - about 3 kg).
