How concrete is broken, how concrete ground is broken

There are three ways to crush concrete:

First, the use of carbonized crushed concrete:

Carbonization damage is due to the neutralization reaction between acid gas and water and alkaline concrete.

Salts are formed on the surface of the concrete, which causes the concrete to pulverize and fall off, thereby deteriorating the concrete.

Carbonization of concrete is a type of chemical corrosion to which concrete is subjected. CO2 gas in the air penetrates into the concrete and reacts chemically with its alkaline substances.

After the formation of carbonate and water, so that the alkalinity of the concrete.

The process of lowering is called concrete carbonization.

Also known as neutralization.

Second, the use of chloride salt to crush concrete.

In the presence of chloride ions.

In the presence of an environment, the corrosion process of the steel bar will be exacerbated, and when these harmful substances enter the concrete through the liquid water transport pipe, they will become associated with the silicates in the concrete.

A reaction occurs that causes the volume of the concrete to expand internally, thus destroying the concrete. Chloride ions mainly erode concrete through diffusion, osmosis, capillary adsorption, etc.

Chloride attacks can vary in different environments: concrete porosity.

At low levels, capillary absorption is the main effect; When the concrete pore is saturated, the diffusion effect at room temperature is the main effect. Osmosis in high-pressure environments.

Mainly. In general, the three invasion modes can exist at the same time, but diffusion is the main one.

3. Crush concrete through freeze-thaw cycles.

The freeze-thaw damage of concrete mainly has two aspects: frost heave cracking and surface spalling. Since the 30s of the last century, scientific researchers from various countries have done a lot of research and put forward a series of hypotheses. The hypotheses put forward mainly include the theory of ice separation layer, the theory of water filling coefficient, and the theory of hydrostatic pressure and osmotic pressure.

theory and temperature stress theory, etc.

The ways to make concrete crushed are:

1. A concrete softening and crushing method, especially involving a softening and crushing method that uses physical, chemical and other principles to soften and crush the excess concrete that must be removed in the building construction or the temporary concrete components that need to be dismantled. Before the concrete component solidifies and hardens, the cannula coated with the agent is vertically inserted into the concrete in a plastic state, and then the cannula is pulled out, and a lot of evenly distributed expansion holes are formed in the concrete, and another agent is coated in the hole, and then the purpose of removing the excess concrete is finally achieved by squeezing and knocking. It is labor-saving, time-saving, and effective than the current method.

2. Use a large crushing excavator with a crushing drill bit, a small air compressor, and a micro manual hammer and chopping to crush concrete.

Concrete is crushed into stones, which can be used directly with a crusher.

1. The concrete stone is large: if the stone is about 1 meter in size, it should be crushed with an excavator with a drill bit first, and then usedJaw crusher is carried outCoarse crushing, which can be broken to about 10 cm, enters through the conveyor beltCone breakingIn the middle of fine crushing, you can come out and other specifications of stones.

2. The concrete stone is smaller: if the concrete block itself is only about 10 cm, it can be used directlyHammer breaking, or counterattack breaking.

Large concrete batching plant.

The construction site generally uses a large crushing excavator with a crushing drill bit, a small air compressor, and a micro manual hammer and chopping machine.

When looking for a crusher suitable for concrete manufacturing, you must first focus on its use and material characteristics before making a further selection. Ordinary concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand and gravel, mixed with chemical admixtures and mineral admixtures if necessary, matched in appropriate proportions, and hardened by uniform mixing, dense molding and curing. The main materials are sand and gravel, which are generally crushed from medium and hard ores.

According to the hardness of the material to be crushed according to the need, considering the use environment and the approximate fineness of the discharge, the hydraulic cone crusher is generally selected for concrete crushing.

If the ground is broken in a small area, you can try it with this gasoline pick<>

How do you break concrete floors? Kiss! Hello, glad to answer for you.

The methods of concrete ground crushing are: 1. If you want to break the concrete quickly, you can use the crushing hammer, which is hit by external force, which can bring a certain impact ability and crush the structure of the concrete. However, relatively speaking, the strength of concrete is still relatively high, so at the construction site, the concrete can also be quickly broken by pressing oil through hydraulic tongs.

2. Therefore, related mechanical equipment has been developed, and there is a hydraulic tubing splitting machine, which is operated by hydraulic power. It has a splitting capacity of up to 1,000 tons of force, and in a matter of seconds, it can easily split thousands of tons of concrete and separate it from the concrete structure. 3. If it is a poured concrete floor, there is no need to use such large machinery and equipment, and it will be handled by professional construction personnel.

For example, with a small crusher, the concrete floor can be quickly crushed by continuously rolling on the concrete floor. It is also possible to use a hand-held cutting machine, which needs to be operated by hand, and can also quickly crush the concrete floor. Hope mine can help you!

Do you have any other questions?

Summary. The concrete can be quickly broken by external force by the crushing hammer;

It can also be used to press oil by hydraulic tongs to quickly crush concrete;

You can also use a hydraulic tubing splitting machine, which can be operated by hydraulic power, and its splitting capacity can reach thousands of tons of force, and within seconds, thousands of tons of concrete can be easily split.

How concrete is broken.

What kind of way to save money?

Is that fast?

This kind of work is fine.

AbstractNowadays, there is no way to destroy concrete unconsciously, because concrete is very strong, and it is impossible to destroy it without movement.

What method is used to crush concrete quickly.

Rapid crushing of concrete can be done by a crushing hammer, which is struck by external force, which can bring a certain impact capacity to crush the structure of concrete. There is also the hydraulic tubing splitting machine, which is operated by hydraulic power. It has a splitting capacity of up to 1,000 tons of force, and in a matter of seconds, it can easily split thousands of tons of concrete.

What is the method by which concrete can be destroyed without you knowing?

Nowadays, there is no way to destroy concrete unconsciously, because concrete is very strong, and it is impossible to destroy it without movement.
