How many cubes of concrete are in a Kamaz mixer (concrete mixer)

The question of how many cubic meters of concrete are in a Kamaz mixer arises when implementing large-scale projects with large volumes of construction. The concrete solution used in the construction of a building or structure must be supplied quickly and in large quantities, and therefore preparing the mixture at home is irrelevant.

Concrete mortar may be needed when pouring a foundation, plinth, blind area, floors, platforms, paths, etc. Often, craftsmen prepare the mixture with their own hands or using a concrete mixer. Despite the simplicity of the process, it is important to calculate everything: the volume of the cement mixture, optimal proportions, time (to quickly use the concrete after mixing).

The preparation of large volumes of concrete is best left to professionals. In this case, it will be possible to obtain the required amount of solution at the specified time, prepared according to technology and corresponding to all parameters and characteristics.

To accurately calculate the amount of material, you need to know how many cubes of concrete the Kamaz mixer can hold. It depends on the model of equipment, the properties of concrete, and other important nuances.

What are the advantages of ordering a mixer?

The volume of concrete in the mixer is quite large. All components of the solution are mixed at the factory, loaded into a Kamaz and sent to the site. At the same time, the customer can be sure that the concrete exactly corresponds to the declared grade and all relevant parameters according to GOST. Concrete is delivered to the site in finished form and supplied to the pouring site.

Advantages of using a concrete mixer truck:

Delivery of freshly prepared mixture directly to the site
Exact compliance of the brand and technical characteristics with GOST
Possibility of supplying the solution directly to the formwork
Significant reduction in the share of manual labor - due to the absence of the need to prepare the mixture yourself and deliver it to the site (the solution is supplied through a chute)
High speed of work implementation, absence of unnecessary seams, areas with low-quality concreting
Delivery of concrete to any distance - small and large factories provide the service in Moscow and the regions, with precise adherence to transportation time

Concrete in KamAZ retains mobility, homogeneity, does not dry out and does not delaminate. Many modern models are equipped with pumps and various types of hoses to effectively move the mixture over a distance of several meters or more.

ABS technical specifications

The safety of the concrete mixture during transportation is ensured by the constant rotation of the drum, inside of which there is a mechanism with mixing blades. The mixer is unloaded by the reverse movement of the blades. When ordering a concrete mixer truck, you must consider the following characteristics:

Drum volume. Manufacturers of construction equipment produce drums of various sizes: from mini-mixers of 2 m3 to large ones of 15 m3. Mixers of impressive volume are used in the construction of large-scale projects, for example, when pouring a foundation;
Mixer filling capacity. Given the stated technical characteristics, it is worth considering that ABS is almost never filled to capacity. This is due to the tightening of fines for overloading since 2015. As a rule, the actual filling of the drum is 1-3% lower than the maximum;
Sleeve or gutter length. The device through which concrete is unloaded from the mixer has a length of 1.5-2 m. Suppliers often offer elongated hoses, and the unloading time increases accordingly;
Weight of loaded concrete mixer truck. This parameter is important when delivering within the city, where there are weight restrictions for special vehicles, as well as when driving the vehicle on viscous soil. In many cases, it is more economical to order two or three 6cc mixers instead of one for 12-15 m3.

Types of mixers and their parameters

The Kamaz mixer is a truck belonging to the class of special equipment, which is equipped with a rotating pear-shaped container where concrete solution is transported. According to GOST 7473-2010, the mixture does not experience the effects of precipitation, ambient temperatures, or ultraviolet radiation during transportation. The solution remains homogeneous, fresh and of the highest quality, suitable for any task.

When concrete trucks are used for transportation, any risks of cement mortar leakage, drying out, delamination, exceeding the service life, freezing in the cold or early setting are eliminated. If the solution is transported over long distances, various plasticizers are added to the composition to extend the time it retains its properties.

To answer the question of how much concrete is in the mixer, you need to know exactly the model of equipment and brand, and the characteristics of the solution. The most popular on the market today are the models of the Kama Automobile Plant, which produces gravity reversible ABS based on the KamAZ chassis 65115 and 69343, 63963 and 53229-15, etc.

The mixer capacity can vary from 5 to 12 m3. The greatest demand is for equipment with a capacity of 9 cubic meters.

Modern automobile concrete mixers are equipped with a hydraulic drive, which has replaced the mechanical mixing method. After the concrete is immersed in the mixer, the solution is mixed using drums with spiral blades. The mixture is unloaded in the back/forward direction with the reverse rotation of the blades. A modern automixer can deliver concrete at temperatures from -30 to +40 degrees.

How to prepare concrete for a concrete mixer:

All dry components are loaded into a container, covered with water from the tank, and mixed during transportation.
Preparation of the mixture at the factory, pouring the finished solution into the mixer, delivery

To facilitate work, automobile concrete mixers use: standard or extended chutes up to 7 meters, supply hoses and pipes, concrete pumps, special transport belts with the ability to unload up to 14 meters. A telescopic boom is also used, thanks to which it is possible to increase the length of the feed to 50-60 meters.

There are several ways to determine how many cubes of concrete are in the mixer. The volume of the solution in the container is not equal to the geometric volume of the drum itself, but is determined by the capacity/yield of the finished solution. After all, part of the free space is used for effective mixing of concrete. According to GOST, the difference is 4-6 cubic meters.

At the same time, the mixer capacity is a factory technical characteristic by which the maximum load level of the concrete mixer truck is determined. The customer pays for the volume of concrete that is actually delivered, and not for how many cubic meters hypothetically go into the mixer. Thus, the capacity of a Kamaz concrete truck mixer with a geometric volume of 8 m3 delivers a maximum of 5 m3, which is due to the capabilities of the chassis and the carrying capacity of the vehicle.

The question of how many cubes of concrete are in a Kamaz concrete mixer is relevant for many. The range of special equipment from this manufacturer includes about 20 machines. And each of them assumes a certain amount of capacity, the size of additional devices, and functions.

What to look for when choosing an automixer:

Drum volume - affects the speed of the machine, the amount of mixture, and the level of load on the road surface.
Passability – especially if delivery to remote regions is planned.
Engine power also affects the speed and ability to transport large volumes of solution.
The total weight of the equipment - not all loaded mixers can go everywhere, especially if access to the construction site is difficult.
Drum rotation speed affects the efficiency of concrete mixing.

Device

The design features of an automobile concrete mixer are determined by the need to prevent precipitation from entering the finished concrete mixture. The safety and uniformity of concrete is achieved by rotating the drum during movement.

The mixing drum is installed on the KamAZ chassis at an angle of 10 degrees. Special spiral blades are installed inside it. When they rotate in the opposite direction, the concrete mixture is unloaded. Concrete flows out of the container through installed gutters. One of them is installed directly in the concrete mixer, and the second is pulled to the machine at the unloading site. Special pumps can also be used for these purposes.

The mixing drum drive can be mechanical or hydromechanical. In the first case, power is taken from an autonomous power plant through a mechanical transmission system. When using a hydromechanical drive, power is taken off through a hydromechanical transmission.

Principle of operation

The operator drives the mixer to the materials storage area and places all the raw materials needed for production into the mixing drum with ladle. Then the mixing drum begins to mix all the materials, after the concrete mixing is completed, the operator sends the concrete mixture to the designated construction site, during transportation, the self-propelled concrete mixer will continue to mix the concrete to prevent the concrete mixture from freezing.

Indicators affecting mixer capacity

Mixing drums of concrete trucks based on KamAZ can have different dimensions and capacities. How many cubes of concrete are in one mixer depends on the model of the machine and the type of structure. Typically the drum volume is 5-12 cubic meters.

If serious construction is planned, large machines capable of delivering 10-12 m3 are chosen. But it is worth remembering that such a Kamaz requires considerable dimensions and will not be able to enter all construction sites.

The best choice is considered to be equipment with a volume of 6-9 m3, which is why these models are most common among manufacturers.

It is worth remembering that each mixer has a certain tilt angle in the range of 10-15 degrees. The inclined position of the drum and the internal blades in the form of screws guarantee convenient and complete loading/unloading of the solution. The water tank is used to flush the tank after draining the mixture and to prevent it from solidifying on the walls of the tank.

All Kamaz mixers have different dimensions, weight, and loads. Only the width of the vehicle remains standard, equal to 2.55 meters (for large mixers) or 2.50 meters (for other models). The height may also vary.

Structures – self-loading concrete mixer truck China

The self-loading self-propelled concrete mixer has a compact structure and is mainly composed of six parts : Under the mixer there is a chassis, which is designed to support the mixer. The powerful motor of the concrete mixer with skip hoist can provide power and ensure that the machine can work efficiently. The mixing drum is driven by a powerful motor and ensures fast mixing, high quality mixing. The hydraulic system of this self-propelled concrete mixer device is the core of unloading materials, this unloading method has been widely used. And its discharge speed is quite fast, which can effectively save construction costs. An independent water supply system can continuously supply water to ensure the normal operation of the machine. The operating room space is small, but can provide an ideal workflow. It has an attractive appearance and compact structures, all compositions fully interact with each other and work efficiently.

Parts of Self Loading Concrete Mixer

What you should pay attention to

Before ordering a building mixture and calculating how much Kamaz concrete takes, you need to carefully prepare everything. After all, ready-made concrete will not stand for long and will begin to harden fairly quickly, so it must be used sparingly and not be distracted by other tasks.

What you need to do when ordering the mixture:

Provide access roads for concrete mixers - you may need several unloading points (for significant volumes of monolithic work).
Clear the area for parking the mixer, from where the supply will be carried out - it is desirable that the distance is 8 meters from the edge of the trench. The slope should not be more than 5%, the dimensions of the site should be at least 6 by 8 meters.
Prepare all the tools for work - a vibrating plate for compaction, and other devices.
Think about where the excess mixture will be drained - you can assemble formwork for some small structures (barbecue, fence, etc.).
Order delivery only from trusted manufacturers, having previously read the reviews - after all, it will be difficult to control the volume of the mixture; a lot depends on the honesty and integrity of the supplier.
It is better to plan delivery in the morning so that you have time to use up all the solution.
If you need several mixers, you need to first draw up a schedule for the arrival of Kamaz trucks and a work plan. It is advisable to leave a gap of at least 2 hours between flights.
When receiving the mixture, be sure to check the delivery note, a certain sample quality certificate for the solution, which indicates the brand, volume, etc.

Delivery of concrete mortar using a KamAZ mixer is an excellent opportunity to save time, money and effort by obtaining a high-quality mixture that meets all requirements.

The lineup

The model line includes variations of vehicles that use various models of KamAZ trucks as a basis. This point largely determines the operational potential of the vehicle.

KamAZ 581453

The three-axle concrete mixer has a 6x4 wheel arrangement. The truck is equipped with a hydromechanical drive and a reliable power plant made in Germany. The planetary gearbox was manufactured in Italy. The main functional elements subject to the greatest wear are made using high-strength steel. This moment ensures the overall maximum service life of the machine. The model is designed for use throughout the year. This becomes possible due to the fact that the chassis engine heats the liquid in the water tank with exhaust gases.

Options for calculating the amount of solution

There are several ways to calculate how much concrete will go into the mixer. Each master chooses the most suitable one for him.

Option 1

It does not give exact results - rather, it is an approximate calculation, which is based on the mass of concrete and assumes the personal presence of a specialist at the plant when washing the drum and loading the mixture. Before filling the concrete mixer, it is weighed (net weight), after filling the manipulations are repeated (gross weight). Then the first value is subtracted from the second value and the mass of the loaded material is obtained.

To calculate the number of cubes of mortar in the drum, you need to divide the weight of the concrete on the invoice by the density.

Density indicators:

500 kg/m3 – ultra-light concrete, foam concrete
500-800 kg/m3 is lightweight concrete
1800-2400 kg/m3 – indicator of heavy concrete

Option 2

This method allows you to calculate the volume of the mixture and the total load of equipment on the road surface. One cubic meter of the mixture weighs up to 2.4 tons - which means there are 16.8 tons of concrete in a 7-cubic drum.

The empty weight of a 7m3 truck mixer is 12.4 tons (curb weight), a loaded 7 cc concrete mixer truck weighs 29.2 tons.

Option 3

On average, a cubic meter of mixture is loaded in 10 minutes. If you track the time of unloading, you can approximately calculate the volume of the supplied mixture. First, the number of minutes of unloading is determined, then divided by 10. This way you can get the number of cubes of the mixture.

When choosing a reliable and conscientious supplier, you don’t have to worry about how many cubes of concrete fit in a concrete mixer. It is enough to calculate the volume of solution needed to complete the work and determine the optimal delivery time. Everything else is the responsibility of the supplier.

Automotive concrete mixers KAMAZ

KAMAZ PJSC is a major manufacturer of trucks. The first truck rolled off its assembly line back in 1976.

Currently, the company is trying to keep up with the times, improving its products taking into account environmental standards, ergonomics, and using components in designs developed by recognized luminaries of the automotive industry. A big event was the start of production of trucks with gas engines in Naberezhnye Chelny.

Currently, the concern produces about twenty ABS models, and additional opportunities opened up after joining the group.

What is typical for KAMAZ special equipment:

Compared to foreign analogues - affordable price.
Excellent performance characteristics, reliability, service life.
Adaptability to difficult road and climatic conditions.
The ability to carry out simple repairs with your own hands.
Available spare parts and components.

Using this technique, you can easily deliver concrete mortar to a construction site, as well as prepare it directly on site and distribute it around the construction site. If this topic interests you, we suggest you watch the video in this article.

Two-axle ABS are currently not in great demand and the leading ones, KOMZ-Export, which produces products under the Tigarbo brand, including those producing concrete mixer trucks on the KAMAZ chassis, have refused to produce them.

Three-axis models are the most relevant now. They are equipped with mixers with a useful volume of up to 9 m 3 . And here, mixers installed on the KAMAZ chassis are popular due to the budget selling price, cheap spare parts, usually available, and the possibility of self-repair of equipment.

While in this segment it is still possible to compete with the products of Chinese concerns, in the four-axle sector this is becoming increasingly difficult. Let's look at the most popular models of concrete mixers on the KAMAZ chassis.

Concrete mixer truck 58148Y

The concrete mixer is installed on a four-axle chassis. Belongs to the Euro-4 environmental class. This equipment is equipped with a large-capacity drum (up to 8 m3 of finished mixture) and is intended for transporting concrete mixtures to large construction sites. It is fully adapted to the road and climatic conditions of various regions of Russia. Maximum travel speed is 60 km/h.

The base cost of the model is within 4.5 million rubles. An analogue of this concrete mixer is ABS 9DA from KOMZ-Export CJSC, made on a KamAZ chassis.

What characteristics does this TIGARBO concrete mixer truck have:

KAMAZ 6540 also acts as a chassis;
the volume of concrete delivered by this mixer has been increased to 9 m 3 ;
The water tank capacity is 800 l;
autonomous motor for the mixer;
The total weight of the ABS reaches 32 tons.

The car shown in the photo costs 4.5 million rubles. There are 9 models of concrete mixer trucks in the line of KOMZ-Export CJSC. However, they do not actively use the KAMAZ chassis, preferring other manufacturers.

Concrete mixer truck 581462

This ABS is installed on a three-axle chassis and belongs to the second environmental class. A little obsolete, not the most powerful in terms of performance (the useful volume of the drum does not exceed 6 m3), but a reliable mixer. The average fuel consumption of a car, depending on the operating mode, varies between 28...31 l/100 km.

The cost of a used mixer is in the range of 850...950 thousand rubles.

Important! A good option for purchasing budget equipment is to purchase it from storage, through conversion. The cost of the models is not much higher than the price of used machines (and often lower), however, these copies have not been in operation and only require maintenance to start working.

Concrete mixer truck 58147A

This machine is designed for operation at temperatures of -20…+40 degrees. To ensure ABS operation at lower levels, a “winter package” is installed. The big advantage of this model is the use of European equipment: the chassis is equipped with a Cummins ISB6.7 300 engine (ecological class 4), and a ZF-9S gearbox is installed.

The hydraulic drive system is equipped with high-quality and reliable components of European and domestic production. The price for such special equipment starts at 3.4 million rubles. A two-year-old used KAMAZ 58147A concrete mixer truck with a mileage of about 50 thousand km can cost 2.3 million rubles.

Problems of concreting with homemade mixture

In critical construction projects, designers, when calculating the strength of reinforced concrete structures, set class “B”, and the composition composition is calculated for grade “M”. Concrete manufactured in accordance with GOST in factory conditions maintains the M/V ratio. A makeshift batch of the required brand may not ensure that the load (B) on the strip foundation from the building frame is accepted.

If a monolith is formed in formwork and with reinforcement, pouring must be carried out quickly and continuously. A break in the supply of concrete will be provided not by a monolith, but by a layer cake, which will quickly collapse from the gap at the joint due to a decrease in frost resistance and corrosion of the reinforcement. Any object is poured continuously and in full, with the mass compacted by vibrators.

Organizing the mixing of cement mortar locally in large quantities is not economically viable. Manual labor of workers will cost more than buying a ready-made composition. Transport costs will remain - you will need to bring in components, water, rent, or buy a low-power mixer.

Selection of equipment regarding design features and required volume

Characteristic features of designs that are important to consider when choosing a model:

The most durable transmission method is considered to be a gearbox, but more well-known modifications have a ring gear, which is easier to repair.
In addition, the engine must be protected from water, since the system is located in the open air.
The presence of wheels will make transportation easier.
The functionality of loading ingredients and unloading the finished mixture is also important. You can do this manually yourself or with the support of a special bucket.

In addition, the installation can be equipped with dispensers. And, the material of the drum body is steel no thinner than 1 mm, since concrete corrodes the alloy.

How to save money when buying BSG

When ordering a composition for concreting, the client should know that the higher the brand, the higher the cost of a BSG cube. Therefore, if M200 is required for the foundation during one-story construction, there is no need to order M250. Order goods in advance so as not to pay for urgency and receive bonuses.

Calculate the need for BSG by volume with an addition of 10% for losses. You can use a calculator or ask to calculate the total volume when ordering. There must be an accurate measurement of the internal volume in the formwork, neglecting the reinforcing mesh.

The formwork must be installed in advance, before the concrete is unloaded at the construction site. Provide concreting of architectural forms with the remains from the mixer. Create all conditions so that the entire ordered volume of concrete mixture is used.

It is necessary to take into account that the calculation for concrete solution and transportation costs are summed up. If the client found BSG on sale from a site 30 km from the construction site, the total cost of the goods from the nearest RBU will be less.
