hyperpressed brick

Hyperpressed brick - a kind of building material, which is manufactured by the method of semidry hyper-pressing of limestone-cement mixture with the stage of its subsequent hardening: by placing in steaming chamber, or in a heated room.It is designed mainly for cladding buildings of different types.

Despite its name, hyperpressed brick refers rather to the group of materials under the title "artificial stones".With his usual bricks have in common only the shape and the main method of application.Unlike traditional ceramic brick, this type of small-piece articles appeared on the market recently.Its production was made possible with the rapid development of innovative construction materials manufacturing technology.In the near future, the development of mass production and reduction in the cost of manufacturing of bricks hyperpressed able to occupy the niche of natural stone materials, and ceramic brick.

composition of hyper-pressed bricks

limestone-cement mixture used for the production of this type of brick, including: high-grade cement (8-15%), iron oxide pigments (2-7%), as well as the main raw material (85-92%): limestone-shell rock, culling from the production of crushed stone, marble, Stipa, dolomite, marl, blast furnace slag, a battle of ceramic bricks, from production waste, cut facing stones, enrichment of coal, ore, etc.

production technology

technology hyper involves molding bricks from a mixture of hydrated granular mineral materials under ultrahigh pressure.Impact compression provokes a strong mutual friction particles mixture, which leads to their adhesion to each other on a molecular level, rather than a simple adhesion.This process does not require exposure to high temperatures in comparison with the same firing clay bricks.This technique is also referred to as dry pressing "cold welding".As a consequence, hyperpressed brick has the texture and characteristics (strength, moisture, frost) as close to the natural stone.

Molded bricks initially are dried in the steaming chamber, or in a warehouse.Drying provides a set of partial products branding strength.The final strength characteristics bricks gathering in the masonry of the month at positive temperatures.This technology allows for high-precision products with design sizes (range deviations of 0.2 - 0.5 mm).

is worth noting that the state has not yet developed a standard for hyper-pressed bricks.It is produced on the basis of specifications to the product obtained by hyper and in accordance with standards (size, purpose), existing for the ceramic brick.

Types

Brick hyperpressed classified:

  • intended: Private, front;
  • by design: full-bodied, hollow;
  • shape: right parallelepiped shaped, "a fragmentary stone".

Dimensions and weight

size of hyper-pressed bricks:

  • Single: 250 × 120 × 65 mm;
  • narrow: 250 × 60 × 56 mm;
  • stretcher: 250 × 85 × 65 mm.

It often products with a length of 230 mm and a thickness of 65 mm with the combined width of 50, 56, 100, 107 mm.

Weight hyper-pressed bricks: 4.2 kg (for standard size 250 * 120 * 65 mm).

Specifications hyper-pressed bricks

  • strength: 100-400 kg / cm²;
  • volumetric weight: 1900-2200 kg / m³;
  • frost resistance: up to 300 cycles, F30-F300;
  • conductivity: 0,43-0,9 W / (m · ° C);
  • water absorption: 3-7%;
  • brands: M100 - M300;
  • fire: group NG - non-flammable.

Properties

  1. resistance to various aggressive media, different climatic influences.
  2. high strength characteristics superior to similar characteristics of silicate and ceramic products.
  3. Perfectly smooth surface that allows for a fast laying of the variety of bricks, as well as giving a saving of masonry mortar, labor.
  4. lack of breaks and cracks.
  5. more than solid durability lifetime (about 200 years) while preserving the aesthetic appearance of the masonry.
  6. The possibility of any kind of mechanical processing on site.
  7. high strength bonding hyperpressed products with cement mortar, which ensures high strength of the masonry.
  8. Laying of hyper-pressed bricks are allowed to carry out year-round.
  9. relative affordability.
  10. Sustainability.

Benefits

The advantages of hyper-pressed bricks are:

  1. material requires high firing costs;
  2. in the manufacture of bricks, you can use a variety of waste production;
  3. virtually waste-free production;
  4. possible to manufacture finished products with a lot of different textures and colors;
  5. the possibility of high humidity and high temperatures;
  6. no limit number of storeys constructed buildings;
  7. ability to perform all types of masonry as the main structural elements and finishing;
  8. possible to use for home decoration and landscape design;
  9. possibility (when the initial material) wide subsequent simulation of properties and characteristics;
  10. small number of waste during transportation and installation.

Disadvantages The disadvantages of hyper-pressed bricks are:

  • relatively high price narrows the range of the current use of this material;
  • need for drying before laying hyperpressed products (as long as possible);
  • significant load on the foundation, especially in the application of solid bricks.

Application

Hyperpressed brick is often used today for arranging foundations, load-bearing structures, basements.Quite often it is used for lining the outer and internal wall structures, columns, facades, pedestals, fences, window decoration, doorways, arbors, fireplaces.Also, it is highly demanded in the landscape design.The extremely high strength of masonry makes it possible to withstand the regulatory requirements of residential, industrial, special objects that are at risk of possible landslides, earthquakes, shock waves and other natural and man-made threats.

photos and videos to illustrate all the options of using hyper-pressed bricks, and represent a wide variety of options for design solutions with its use.A lot of positive feedback about the properties and usability of this material suggests that in the near future brick hyperpressed able sure to press the apply now popular types of bricks - ceramic, silicate.Its use will increase the weight in the development of new products of this type with different properties.
