Polymer concrete - the technical characteristics of the

Modern needs of the construction industry contribute to the emergence of newer and more advanced materials. So, polymer concrete recently began to gain great popularity. We will tell you about this unique composition further.

Properties

Many authoritative experts believe that polymer concrete is a material that will soon conquer the construction market. As far as this statement is relevant and truthful, let us see below.

History reference

As we have said, this material is innovative. However, there is evidence that it was used several thousand years ago in the construction of the Egyptian pyramids. Of course, this is only a similar technology.

The blocks from which they built the pyramids consisted of the following components: silt from the Nile River, limestone, gravel, attorney salt, ash, and crushed lime. As a result, they were able to stand for so much time without becoming cracked. At the same time, they did not form a so-called "tan" (any natural stone is covered with it over time).

Virtues

Now it is time to get acquainted with the advantages of this know-how:

• Concrete has a very high strength.. Even cutting reinforced concrete with diamond circles can hardly cope with its task.
• Long life. Significantly higher than its ancestor.
• Very low shrinkage during drying.
• High compressive strength. This allows you to withstand enormous loads.
• Resistant to almost any acid..
• Polymer concrete technology is solidly different from all known. The fact is that in its production only environmentally friendly raw materials are used.

Interesting: the permeability of this material is comparable to natural granite. To date, only he can boast of such dignity.

• Polymer concrete products have a low degree of greenhouse gas emissions.
• Quietly maintains temperature drops. It retains all its properties even when heated to 1300 degrees.
• Does not wear out with time and does not crumble..

Among all this variety of advantages, there was one drawback - the high price. However, in the future, the situation is likely to change. The fact is that this is a new technology, which means that for some time its cost will be significantly reduced.

Specifications

The enormous increase in popularity is due to the fact that polymer cement concrete has very high characteristics, which are left out of business by all of its main competitors. We will get acquainted with them:

Note! The above values ​​are controlled by the construction norm of 525–80 from 01/01/81.

It is also worth bringing to your attention and chemical resistance to various substances:

From the data of this table it is clear that this material meets all the standards of chemical resistance. Hence, the polymer protection of concrete floors carries a high efficiency. Therefore, this technology is often used in industry.

Cooking

Now consider how to independently prepare polymer concrete. In fact, this is a simple procedure that will only require you to strictly observe the proportions.

Ingredients

Consider what we need:

1. Potassium hydroxide. These are hygroscopic crystals with no color or smell. They instantly melt in air, so they must be stored in vacuum packaging and taken out before use.

This substance is very aggressive, it has a strong effect on the mucous and skin. For this reason, the instruction prescribes wearing protective equipment (glasses, gloves, respirator) when working with it. Otherwise, there is a great risk of injury, especially the eye.

1. Liquid glass (surely many of us, having read this phrase, will think about the element that fill our windows). In fact, they are colorless crystals without any odor. They consist of silicic acid and alkaline potassium.

You can buy it in the nearest agricultural store. The fact is that liquid glass is often used by gardeners to fertilize various crops.

1. Fly ash. This ingredient can be obtained independently (if you burn a certain amount of solid fuel) or you can buy it at the hardware store. Experts say that the addition of ash makes Polymer asphalt 75% stronger and more durable.
2. Chilled water at room temperature. It should not contain any impurities. If you add tap water, then it must be allowed to stand for a while.
3. In addition, you can use any additives (for example, slag or dye). This is necessary in order to obtain an attractive texture and improve the characteristics of the mixture.

Instruments

Now consider what tools you need:

• Remedies already mentioned.
• Container for mixing ingredients (preferably glass).
• Wood spatula for mixing.
• Electronic balance. Remember that it is very important to keep all proportions. If we are talking about a small amount of the solution, then simple kitchen scales will do.
• Mold for casting.

Cooking secrets

It is time to answer the question of how to make polymer concrete with your own hands.

So, for the preparation of 1 liter of the mixture, we observe the following proportions:

1. Potassium hydroxide – 160 г.
2. Liquid glass – 200 г.
3. Zola - 540 y.
4. Water - 100 ml.
5. Slag (it is needed to impart particular strength, it is not necessary to add it) - 300 g
6. Special cement for polymer concrete - 20% of the total.
7. Supplements at will (their consumption should be indicated on the package).

Note! When mixing the mixture will heat up due to the release of carbon dioxide, so do not be alarmed.

Mixing ingredients must be carried out in this order:

1. Pour into the tank clean water.
2. Add cement to it.
3. Then we pour ashes, slag and liquid glass in equal shares.
4. Then we fill up the remains of components.
5. Now using the construction mixer you need to mix everything thoroughly. Remember that the mass should be perfectly homogeneous. Otherwise, the polymer concrete will not work durable.
6. The resulting mixture can be poured into a form or formwork for solidification.

It will completely harden in only 3 weeks. Only after this period can we conduct any operations with it, for example, diamond drilling of holes in concrete.

It is worth noting that the experiments to create ideal proportions are carried out to this day. In this regard, people often begin to change their own recipes. Therefore, you can try yourself in this path.
