Vibropressed tiles (paving) - the latest development of European engineers.
Thanks to a special formula, it is possible to achieve the production of incredibly high-quality tiles with a high level of strength and frost resistance. It also has the correct geometry, so it is not at all surprising that it is gradually crowding out the granite surface of European streets.
- Low cost.
- Concrete does not create a radiation background, unlike granite.
- Universal material to which you can give any size, color, pattern. Easy to work on.
- The rough surface makes it a very attractive material for use in winter. Due to this property, it is practically non-slip, which is very important in the conditions of our climate.
First, make a concrete mixture. The mixture for tiles or for curbs will be significantly different from concrete mortar having a different purpose. The mixture must be hard, there should be little water in it. For good mixing of the mixture, a special planetary concrete mixer will be required. In addition, you need a computer that monitors moisture levels and determines readiness.
The next step is loading into the mold and production. With the method of vibropressing, the mixture laid in the mold is pressed not only with the help of the press, but also with special vibrators. Through the use of such vibrators, it is possible to get rid of excess water and air. The mixture itself is maximally compacted, which will give the product maximum strength, a high level of frost resistance and low water absorption.
Vibropressed paving slabs need not have the color of concrete. For this, European engineers have developed another special technology. So, during production, they mix two concrete at the same time: the main and the facing. This is due to the fact that high-quality dye is a rather expensive pleasure. And its use is directly related to the final cost of the goods.
A feature of this method is that first, ordinary gray concrete is poured into the mold, and then vibration is turned on. When it settles, the remaining place is filled with colored concrete, and they continue to form tiles. Due to this, it is possible to paint about one centimeter. From this, neither strength nor other quality characteristics are lost, but the dye is significantly saved. Thus, it is possible to make an affordable price. A quality product can be exploited for many decades.
