It is hard to imagine the performance of large volumes of construction work without mixers, especially if there is no possibility of preparing a solution in large volumes directly on the site. In order to make correct calculations, a number of points must be taken into account. One of them is knowing how many cubes of concrete are in the mixer, which makes it possible to determine the total volume of the working mixture and the possibility of one-time transportation of the required amount of mortar.

Car mixer: what is it?

The device in question is mounted on a car chassis. The working element, in which the mixing and transportation of concrete takes place, consists of the following structural parts:

• Drum mixer.
• Auger type agitators.
• Devices responsible for rotating the drum.
• Unloader.

How does it work?

Before we find out how many cubes of concrete are in the mixer, let's consider the principle of operation of this technique. An important factor in the quality of the preparation of the solution is the uniform mixing of the loaded components. Responsible for this momentrotating drum with auger agitator.

The stirrer is a fixed screw, the mixing operation is performed by rotating the drum. When filling the raw material, the mixture on the surface of the screw enters deep into the tank, where it is mixed to a homogeneous consistency. To unload the finished concrete, the drum rotates in the opposite direction. In this case, the screw nozzle will help the contents of the mixer come out, pushing it out forcibly.

Classification

How many cubes of concrete are in the mixer, largely depends on the modification of the automobile chassis and drum. Among the many types of concrete trucks, the main distinguishing parameters are noted:

• Wheel base type.
• Capacity of the working tank of the mixer.
• Methods for unloading the mixture.
• Features of the organization of the rotation of the drum.
• Availability of additional equipment.

How many cubes of concrete are in the KamAZ mixer?

Concrete mixers are available on various vehicle chassis. Domestic units are most often mounted on KamAZ, as well as MAZ, ZIL and Ural. The capacity of concrete depends on the volume of the drum.

Foreign analogues most often use modifications of Scania, MAN, Mercedes, Nissan, Mitsubishi, Volvo trucks. The main factor determining the one-time capacity of the working mixture is the volume of the working drum. In world practice, several standard values \u200b\u200bare adopted, making it possibleoptimize production needs, depending on the scale of work.

How many cubes of concrete are in the KamAZ mixer? In domestic production, the following parameters are provided in terms of the volume of the working drum: from 2 to 12 cubic meters. Most often, mixers with a capacity of five, seven, or nine cubic meters are ordered. Foreign modifications mainly use a volume of 6 cubic meters. m.

Unloading

Unloading the finished solution, regardless of how many cubes of concrete in the MAN mixer or other car, is done in two ways: forward or backward. Frontal unloading is carried out under the direct control of the driver. This method is common among foreign manufacturers.

In the second case, concrete is unloaded through a special opening at the rear of the equipment. This method is practiced in domestic industries, it is considered more reliable.

Rotary drive and accessories

The mixing drum is rotated by a motor with hydraulic and mechanical drives. The power plant is sometimes presented in a combined version. The engine distributes power, which is spent on the movement of the machine and the rotation of the drum. The best option is an autonomous power unit, the power of which is directed only to the rotation of the container and unloading the concrete solution.

How many cubes of concrete are in the MAZ mixer, discussed above. But, in addition to the main drum assembly, most mixers come with a number of additionalfixtures. Among them:

• An elongated pipe in the form of a chute used to unload the mixture. Its length is 1500-2000 millimeters.
• Pump for pumping concrete.
• Extensible derrick for pumping concrete to high-rise facilities.

How to calculate the amount of solution?

An important point is the question of determining the actual volume of the delivered concrete solution. This especially applies to the delivery of the solution in mixers, the capacity of which exceeds the volume declared by the customer. There are several ways to determine how many cubes of concrete are in the mixer.

At the enterprise, as a rule, the weighing of the shipped mortar is carried out. In this case, calculating the volume of concrete is not so difficult. Divide the mass of the mixture by its density, the values of which are given below:

• Heavy grades of concrete with gravel or crushed stone filler - 1800-2500 kg / cu. m.
• Light types of concrete with gas fillers from expanded clay or its analogues - 500-1800 kg / cu. m.
• Aerated concrete - less than 500 kg/cu. m.

In addition, you can find out how many cubes of concrete in the mixer (standard) by the time the drum is empty. On average, unloading one cubic meter of the mixture takes about 5 minutes. Therefore, it will take about half an hour to empty a 6cc machine.

Useful information

It is worth noting that during long-term transportation with loaded mixers, the concrete mixture is prepared directly in the drum.

Bcold season, in addition to standard components, additives and chemicals are added to the composition of the solution, preventing the concrete from freezing quickly.

When choosing a car mixer for transporting concrete, pay attention to the cleanliness of the inner surface of the drum. Poor washing or its absence causes the obligatory layering of hardened concrete residues on the walls. Over time, this mass will only increase, and it will be almost impossible to determine the actual amount of the solution. In addition, the frozen mixture prevents the normal rotation of the drum, worsening the uniformity of mixing the components and the quality of the final product.

Finally

The car mixer is an indispensable assistant on modern construction sites. It is used on large-scale complexes, as well as in the construction of country houses or cottages. In addition, the machine is used for pouring pools, various sites, terraces, columns and other concrete structures. The technique significantly speeds up and facilitates the workflow. Depending on how many cubes of concrete are in the Scania mixer or another vehicle, the final filling volume at the construction site depends. Therefore, before ordering a mortar, it is necessary to carry out accurate calculations so as not to overpay for the surplus or not to re-finish a small area for which there was not enough concrete.
