Equipment for aerated concrete: the essence of the process,

Aerated concrete today has a very high and justifiable popularity. This makes the question of the possibility of its independent production relevant. In this article we will look at the necessary equipment for this.

General provisions

First of all, let's consider directly the material in question, and let's start with the story.

A bit of history

Cellular concrete was patented as far back as the middle of the last century, but was not widely used for two main reasons:

1. Relatively low strength. At that time, there existed GOSTs requiring very high strength properties, which did not correspond to gas-blocks. As a result, they were ranked as heaters.
2. The high cost of gas-forming additives, resulting in significantly increased the price of the products themselves.

In our time, both of these shortcomings have lost their relevance:

1. GOST standards have changed due to higher energy costs, and the emphasis has shifted to keeping heat. In addition, the possibility of additional autoclave treatment, which sufficiently enhances the strength of aerated concrete.

1. Stepped forward technology allowed to make gas-forming substances more accessible and cheaper.

The essence of the process

As you may have already guessed, the whole peculiarity of the creation of gas blocks comes down to the use of special gas-forming additives during the manufacture of the solution. When they come into contact with cements, they cause hydrogen, which swells up the preparing mixture, which in such a state hardens. The resulting cells guarantee a multitude of benefits to the material obtained.

Benefits

• Low thermal conductivity. This is the main and most important reason for the production and use of aerated concrete. Numerous pores filled with air create an excellent heat-insulating barrier, which allows to reduce the cost of heat carriers up to thirty percent without the use of additional insulation materials.

• High noise isolation. The cells “catch” most of the extraneous sounds, which move so well through the structure of heavy concrete and other more traditional building materials.
• Inflammation. A lot of fire safety does not happen, especially if you value yourself and your loved ones.

• Easy do-it-yourself processing. To cut the gas block enough hacksaws to drill a hole - a conventional drill. We can safely say that the internal finishing works and wiring communications will not be difficult.

• Environmental friendliness. There is no release of any harmful substances.
• A light weight. Allows you to save on pouring the concrete foundation and simplifies installation work.

• Regular geometric shapes. This not only simplifies the operation of gas blocks, but also allows the use of special glue instead of the cement mixture to fix them and thereby reduce the thickness of the joints to a minimum.

• Lack of susceptibility to rotting, corrosion, attack of rodents and insects, thanks to which significantly increases the operational period.

Necessary equipment

Equipment for the production of aerated concrete on the complexity of the application, cost and production can be divided into two types:

Unprofessional

If you need to make a small number of gas blocks for the construction of an outbuilding or insulation of a part of a residential building, then you can limit yourself to almost the same set of tools used for concreting:

Tip: It is not recommended to try to knead manually without using a concrete mixer. If with the usual solution you can still achieve a satisfactory effect with the help of a metal trough and a spade, then in this case the gasifier will still not be able to be distributed fairly evenly. As a result, aerocrete will not meet its technical standards.

Such a minimum set will be sufficient for the primitive production of aerated concrete, which differs from the creation of heavy concrete for the most part only by the composition of the solution:

Tip: if you plan to make cellular concrete with a minimum thermal conductivity and use it to warm the room, then it is recommended not to add sand. This will achieve the highest porosity.

The instruction is as follows:

1. We immerse cement and sand in the mixer, add water depending on the state of the solution.
2. After the mass reaches a homogeneous, mushy state, add a blowing agent.
3. After a few minutes, pour the contents into the forms, where the swelling continues and the seizure begins.

Professional

If you need a large amount of material in the calculation for the construction of a residential building, then you will need to do this with appropriate automated equipment for aerated concrete blocks.

Tip: in order to save all the necessary concrete equipment can be rented. So you can make high quality products and not burden yourself with an expensive purchase.

Here are examples of suitable cellular concrete production lines:

1. "Aerated-230 B plus." Technical specifications:
2. mixer volume - 0.23 m³;
3. production speed - one and a half cubic meters per hour;
4. the number of operators - 2 people;

Additional equipment:

• two-meter discharge hose;
• air compressor, contributing to the implementation of the batch;
• all necessary equipment for connecting the compressor to the main part of the installation.

1. "ACM-1MS". Technical specifications:
2. mixer volume - 0.25 m³;
3. production rate - one cubic meter per day;
4. the number of operators is one person;
5. energy consumption - 3 kW;

Equipment:

• mobile mixer-activator;
• template design for cutting blocks with the necessary set of saws;
• pallets with dimensions of 120? 60? 30 in the amount of two pieces for ready-made blocks;
• similar sizes with pallets.

1. "ASM-60SA". Designed for very large volumes of a commercial nature. Technical specifications:
2. mixer volume - 0.7 m³;
3. production rate - 60 cubic meters per day;
4. the number of operators - from two to four people;
5. energy consumption - 10 kW;
6. automated sand and cement feed.

Equipment:

• self-propelled mixer-activator for fine aggregate and binder;
• mixer for additives;
• template design for cutting blocks with the necessary set of saws;
• pallets with dimensions of 200? 120? 30 complete with boards of similar dimensions;
• screw feeder 450 cm long;
• ribbon-like conveyor with ribs 500 cm long.

Tip: at the initial stage it is worth using used equipment for the production of aerated concrete for commercial purposes. This will allow you to save a lot, and after getting enough profit, replace everything with new devices.

Conclusion

Cellular concrete allows you to build a reliable warm building quickly and economically. You can further reduce the cost of building a house by making aerated concrete yourself, which will require the appropriate equipment. If you get all the necessary equipment, you can use it for commercial purposes, opening a profitable production of gas blocks.
