Destruction of concrete: methods. use powder. use of an

Often, during the construction or reconstruction of an object, it is necessary to pre-destroy old reinforced concrete structures. But the fact is that this material has increased strength, otherwise it would not be able to hold onto the structure. Dismantling in this case is a difficult task, so they can use several options, including the destruction of concrete by ultrasound or chemical preparations.

General information

Consider frequently used methods that will help you understand how to destroy a concrete foundation with your own hands:

Advice: when removing the reinforced concrete structure, cutting of reinforced concrete with diamond circles of necessary density helps well.

To understand which method is appropriate for a particular case, you need to familiarize yourself with each and every detail.

The easiest method

You can crush a small concrete structure into separate pieces with a sledge hammer. In this case, the rate of destruction in this case will depend only on your physical capabilities. Therefore, if they are small, you can spend a lot of time and effort on work.

Alternatively, you can drill holes in the punch in several places to reduce the strength of the material, then it will be much easier to destroy it. It is believed that even a reinforced concrete slab can be crushed with a sledgehammer, but is it worth it? Below you will learn about other easier methods.

Use powder

In this section, you will learn how to chemically destroy concrete, as quite often for the dismantling of solid building materials use chemical powders that do not burn or explode.

Популярность данного способа обусловлена тем, что во время процесса отсутствует шум и не образуется лишний мусор, что можно наблюдать при обычном взрыве. Обычно применяют порошок НРС-1, так как он обладает высокой силой разрушения (> 30 МПа).

Below will be offered instructions on its use:

1. Drill holes in the concrete structure with a diameter of 80 mm, the distance between them is from 560 mm.
2. Pour into them the prepared solution - powder with water.
3. Wait about 48 hours, during this period the chemical will begin to crystallize and begin to destroy the building material.
4. After the stated time, on the site of the concrete structure there will be only pieces of scrap that you take to the disposal site.

Tip: to work you may need a service - diamond drilling of holes in concrete with crowns of the right diameter.

Use of an acidic mixture

Experts know how to destroy concrete without physical effort, and what substance has a detrimental effect on it. Therefore, for the dismantling of strong reinforced concrete structures, acid mixture is often used, which simply dissolves the material.

To remove a small amount of solid matter from the surface, it is sufficient to simply pour a substance, such as hydrochloric acid, on top of it.

Tip: act very carefully, otherwise you may get burned or cause yourself another injury.

Typically, the pure acid is used extremely rarely, for this special mixture is prepared.

With its help it is possible:

• dissolve concrete;
• remove it from the bricks;
• wash the remains off the wall.

The mixture contains concentrated acids and inhibitors. The latter are necessary to protect other surfaces when treating concrete. For example, if you need to clean the frozen mixer. The mixture quickly penetrates deep into the material and destroys it, as a result, after a while it will turn into dust that can be easily swept away with a conventional brush.

Tip: You can reuse the mixture, if for the first time the building material is not completely cleaned.

We destroy the reinforced concrete

The above methods of concrete destruction in this case are not as effective. You will have to fight material that is much stronger. Using a punch for making holes is simply meaningless, so it is better to immediately prepare special tools - powerful drills with diamond nozzles.

Only such a tool can do this kind of work. In this case, you can drill holes at almost any angle.

Any methods for dismantling concrete structures described above are not in a position to oversee with diamond cutting. The drill material’s high strength is not a hindrance, so it will cut any thickness. The price of the method is high, but it allows you to quickly cope with the task.

Tip: for cutting a concrete block of large dimensions, you can use a machine with a diamond wire.

Only a professional can carry out work on her, since she has a rather complicated management. The principle of dismantling is to use the hydraulic pressure after the block is wrapped around the rope. The cutting speed depends on the strength of concrete. For example, in particularly difficult cases in an hour you can cut through about 2 m of the structure.

At the same time working with ordinary concrete does not cause difficulties. It is 5 times faster. The machine is usually used for products with a thickness of more than 1 m.

During operation, you must comply with the following requirements:

• constant cooling of the machine mechanism is required, as from a permanent job it quickly heats up;
• near the workplace should be a source of cold running water. In addition, water also serves as a kind of protection for the diamond coating, preventing its destruction and washing away the excess dust, which is formed in the process of work;
• need to have a constant three-phase voltage connectionotherwise the equipment will not work.

Conclusion

The methods of destruction described above are effective and are applied quite widely, although there are many others, for example, hydrocline for the destruction of concrete. With their help, you will be able to get rid of unnecessary concrete goods and start new construction in a short time.
