The most popular building material in the modern market is considered a single sand-lime brick. It is often used for building walls and load-bearing beams in the house. Its popularity is due to the fact that all of this material is done quickly, efficiently, and most importantly economically.
Properties, specifications ↑
This building material is produced by autoclave pressing a special blend that includes: lime, quartz sand, water, and modifiers.
Bricks of this category have very high performance characteristics:
- The thermal conductivity is about 0.56 W/mos. This figure is much less than that of the red ceramic material, because the construction of the external walls of the building should be exactly of one and half silica brick.
- The density of the element. Solid elements are order of magnitude stronger than hollow. For comparison, the density of the solid element is greater than the core density at 600 units.
- The rate of moisture absorption. The crystal structure of this construction material allows to quickly absorb and quickly release moisture. Because it is not necessary to fear the occurrence of cracks on the walls, built of this material.
- The compressive strength and Flexural strength. The most popular brand 150, an indicator of its strength is 50 kg /cm?.
- Resistance to defrosting and re-freezing is on the order of 20-35 cycles.
- Silicate brick bastard is the best option for construction of interior partitions, since this material has a high degree of sound insulation.
- The size of a brick is: 25*12*8,8 cm.
- Weight of one element is about 4 kg.
The benefits of a single brick ↑
During the construction of the walls and ceilings traditionally used hollow brick of the thickened type. The voids in such elements come through and not through. In form they are very similar to the cylinder, and are arranged perpendicular to the base element. Thanks to these cells, the bricks become much easier, thus reducing the load on the Foundation of the house. At the same thermal insulation performance and sound insulation performance are improved many times.
After analyzing all of the above, the advantages of using this building material are obvious:
- The cost savings of time for styling. Bearing partition are placed in two rows plus one additional row of stone.
- A significant saving of consumption of binding solutions.
- Increases the life of the building of a.
- Improves frost resistance and teplokrovnosti walls of the house.
Half bricks can be produced in several colors: pink, blue, red and yellow. To obtain such a variety of colors made possible through the use of special pigments resistant to alkalis. They are added to the mixture at the stage of production.
Besides the fact that stone makes the outside wall of the job fair, they allow stacked wall «breathe», which significantly prolongs the life of the surface.
Features a Queen-size silicate bricks ↑
The weight and size of a silicate brick is slightly higher than the parameters of the ceramic stone. This is because the quartz sand and lime, which forms the basis of the material makes it quite heavy. The components used in the manufacture of this building material characterized by high hygroscopicity, which also affects the weight of the stone.
Using single silicate bricks for construction of building walls, it is conventionally divided into two groups: personal, private. The size of the single element is not related to his species. Sand-lime brick has a standard size: 25*12*8,8 cm.
Facing or face the rock is particularly smooth and beautiful surface faces. They have a perfectly smooth appearance and allows for beautiful decorative styling.
Ordinary stone used for several other purposes. Usually, it comes in white only and is required for the erection of walls and partitions. For such work is not very important the smoothness of the surfaces, as long as the bricks had a dense structure and was sturdy.
The mass of a material depends on its internal structure. Full-bodied item is a solid dense mass, without any holes, voids. Such an element weighs on average 4.5 kg.
Hollow stone inside looks like a combination of different openings, cells or voids. How much it will weigh hollow brick, depends only on their number. On average, the figure is 4 kg.
Why you need to know the weight of the brick ↑
What is the weight of any geometric solid can be calculated according to the formula: body density multiplied by its volume. Such indicators are not very difficult to calculate independently. When performing calculations, be sure to take into account the parameters of humidity, the presence and number of voids in silicate brick, and also the presence of decorative wall finishes. The differences in the weight values depend on the concentrations of moisture in the material. High interest rates can significantly increase the weight of the product. The size of the various cavities and cells of stone, on the contrary, reduces the weight of the brick.
As practice shows, the proportion of the element in the range of 1,300-1,900 per kg/m?. Knowing the formula for calculating the mass of one element, it is easy to calculate how much will be the pressure exerted on the Foundation of the house.
If the calculations are carried out correctly, you can avoid extra costs for arrangement of the ground floor. The house is built will be strong and its walls are covered with cracks just because during construction there was an error in the calculations.
Manufacturer of white silicate brick as a seller always indicate the exact size and weight of the finished product, thereby greatly facilitating the process of calculations.
Scope of use ↑
This building material attracts with its range of different colour faces, hollow, solid, allow the architect to creatively design process of the building, and to create masterpieces of architecture.
Queen-size sand-lime brick is very widely used for laying of internal and external walls. When connecting single, Queen, white and multi-colored stone, at the end you can get a very beautiful and original decoration of the building.
Experts identify some factors under which this type of construction material should not be used. As practice shows, it is primarily due to the climatic conditions of construction and operation of the house, as well as technical features of structures erected.
In the case where the silicate brick is affected by temperature of over 600°C, the tensile strength is reduced, and as a result, the surface cracks appear. This stone cannot be used in the construction of fireplaces, stoves and chimneys. For this purpose, other type of bricks and refractory.
Conclusion ↑
As practice shows silicate one and a half brick is a building material with the best technical and operational characteristics. It is traditionally used for walls, partitions and ceilings in the house. An important advantage of using this material is its cost. It is quite small, resulting in a budget building a house is significantly reduced.
