Manufacture of hyperpressed bricks
Make this material by semi-dry hyper-pressing. The main point is the following: a quantity of water is added to the cement-mineral mixture. Further, under high pressure, the composition is pressed. The brick is laid in a steam chamber on pallets. In this "sauna" with a controlled temperature regime, it should be about 8-10 hours.
In this procedure, the cement contained in the mass, as it should, absorbs all the moisture( as we remember for its "operation" necessarily the presence of water).At the last stage, the finished product should lie in a warm warehouse for 3 to 14 days( depending on the season).As a result, the resulting brick has good vapor permeability, frost resistance, durability.
Those who are interested in the manufacture of this material, you need to know which equipment for the production of hyper-pressed brick will be needed.
So, it is: hyperpress( where the molding takes place), a crusher, consumption and receiving hoppers, a dispenser, screw and belt conveyors, a mobile compressor unit, a concrete mixer, a two-hose owl, a screen for screeching, skip hoists and a warehouse( where the finished product is stored).It is this technique that will allow us to develop profitable production of high-quality brick.
Properties of hyper-pressed brick
So, as already mentioned, this material has much higher consumer characteristics than ceramic bricks. It is due to its composition and manufacturing technology. Let's enumerate them in more detail:
- The frost-proof shows how many cycles of thawing and freezing the material withstands. To date, hyper-pressed brick has the highest parameter, equal to F200( the number of cycles).
- Strength means the maximum load that a brick can withstand pressure from above. In this case, the figure is M200( that is, more than 200 kg).
- The water absorption of is 5%( the lower it is, the better).This means that the facade coating does not absorb pollution, they are easily washed away by rain.
- Heat resistance shows characteristics such as fire resistance, strength and elasticity of the material in the heated state, creep, shrinkage, etc.
- Variety of textures, colors .For example, there may be "torn" surfaces or in the form of "wild stone".The number of shades is more than 70.
- Seismic resistance - the strength of the entire masonry, which is 1.7 times higher than that of silicate or ceramic bricks.
Application of hyperpressed bricks
This material is used for the erection of load-bearing and self-supporting walls in buildings and structures of any number of storeys. Also made of it are structures that require heavy-duty support( police stations, defensive dams, hospitals and other similar institutions).Plus, a smooth surface and a variety of colors allows you to apply these bricks for the facial decoration of fences, facades, arbors, wells, barbecue areas.
Resistance of the material to temperature differences allows using it in any climatic conditions( including in the zone of the extreme north).Because any buildings will be durable.
It is also worth noting that hyper-pressed brick is also used to create garden and pavement paths. They are very durable and able to withstand any weather phenomena. That's why this material has become popular with many gardeners. Not only roads, but also greenhouses, baths are built from it.
