Concrete Mixer Reviews & Buyer Guide.
Who of us does not want to fulfill his dream of owning a house? When building a house, especially a mixing machine is of high importance. Mix your own concrete for the shell.
In our test or comparison table you can see what criteria are important when buying a concrete mixer.
A large drum to mix high quantities of wet building materials such as concrete and plaster quickly and evenly. If you want to mix concrete for 0.2 m², then choose a model with 190 l drum volume from our table now.
Concrete Mixer Buying Guide:
How to choose the right product from the above concrete mixer test or comparison
- A powerful motor rotates the drum to mix sand, cement powder and water into concrete. In doing so, the motor must be able to turn the drum smoothly even when full.
- It is not only the power that makes a good cement mixer. The size of the drum is also crucial. The higher the drum volume, the less often you need to mix new concrete.
- Concrete mixers with an IP45 rating can also be stored outdoors under a tarp when it rains. They are safe from water jets and larger grains of sand.
Who doesn’t dream of building their own home? When erecting the shell, a skilled craftsman can save about 500 €/sqm by grabbing the wheelbarrow and trowel himself. A shell consists almost exclusively of concrete and steel mesh and offers many trip hazards. Make sure you wear safety shoes, work gloves and safety goggles when working so that you can continue building your own home unharmed.
To build your shell quickly and efficiently, you will need a concrete mixer. Use this to mix larger quantities of concrete, spit or screed. Mixing plaster for the interior finishing of your house is of course also possible.
We would like to show you with our buying guide to the concrete mixer comparison 2021, on which criteria you must pay attention when buying a concrete mixer. Particularly important here are the power of the motor and the drum volume.
Are there free-fall mixers for private use?
The concrete mixers presented in our table belong to the category of free-fall or drum mixers.
Concrete is picked up and transported by a spiral inside the drum. In the upper third of the drum, the mix falls down and is mixed in again. These machines are mainly used on private construction sites.
For commercial construction sites, compulsory mixers and truck mixers are used, which can process considerably larger quantities of concrete and other wet construction materials.
It is also possible for private individuals to rent a truck mixer. However, this is associated with high rental prices, especially if you only need concrete now and then. The comparably low purchase and operating costs of a free-fall mixer solve the problem.
Does high performance ensure fast and thorough mixing?
A powerful motor turns the drum of the concrete mixer faster and more evenly. This ensures that gravel, sand, cement powder and water mix properly and do not form lumps.
This is especially important when pouring floor slabs or walls that are made of smooth concrete, i.e. without gravel content. Nothing is more unsightly than finding holes or defective areas in the floor.
If you decide to buy a concrete mixer, you should pay attention to a minimum power of 800 watts. This motor power is high enough to turn even a full drum without any problems and mix the concrete evenly. Buying a model with lower power is only worthwhile if you want to mix small amounts of concrete or only need the machine from time to time.
In the table shown below, you will find the basic recipe for making gravel concrete. However, if you want to mix smooth concrete, simply replace the gravel with sand.
If you build a lot, you need a lot of concrete!
The concrete mixer can be used not only in house construction. Laying a foundation for the greenhouse or a concrete path in the garden also require high volumes of concrete. Furthermore, fence posts, playground frames and the like should be concreted for more safety.
The concrete mixer can also be used to mix plaster, mortar or stucco for the interior of your home. Even if the concrete mixer was mixing concrete just a few minutes ago, mixing other building materials is possible after a quick cleaning. The recipe of the required building material can be changed quickly and conveniently without contaminating the respective materials.
Each building medium must be mixed in different quantities. Plaster and stucco are mainly required in small quantities, whereas concrete often needs to be mixed in masses.
To ensure that you can handle both small and large quantities with a concrete mixer, we recommend a concrete mixer with a drum capacity of at least 150 liters.
If you want to pour a new foundation of 5 x 5 m and a height of about 10 cm, you will need about 2.5 m³ of concrete.
A concrete mixer with a drum volume of 140 liters produces up to 0.14 m³ of concrete in one batch. You will therefore need about 18 pours of concrete.
If you use a mixer with a drum volume of 190 liters, you will only need 13 pours to lay the foundation completely.
Many manufacturers equip their cement mixers with IP44 or IP 45 safety ratings. In this way, the producers ensure that the mixer is not damaged by fine sand and spray or jet water. This specification refers primarily to the installed motor.
Concrete is mixed from water and sand or gravel. Therefore, it is always possible that individual grains of sand hit the motor. It is also common for water to be mixed in via a hose, so there is also a possibility that the motor will be hit by spray water.
When buying a drum mixer, make sure that the manufacturer provides information on the safety level. This should be at least the level IP44. Otherwise, there is a possibility that the motor will not start after only a few working days and may be defective. 5.
Is a large hand wheel useful for convenient pouring?
During a potential concrete mixer test, you would test both the performance, power consumption in continuous operation, and handling of a concrete mixer. It is especially important to make sure that the hand wheel is a good size. This is because a large hand wheel will make it much easier for you to empty the concrete mixer into a wheelbarrow or buckets. Leverage is increased with a large wheel. This means you need less force to move the drum up and down.
Units with a hand bar are poor for emptying, as a lot of force must be applied here to turn the drum. Furthermore, operating the machine with two hands is very cumbersome due to the rod.
When buying a concrete mixer, you should definitely make sure that the hand wheel has a comfortable size. Ask your trusted home improvement store to let you test concrete mixers in terms of how they turn, and find the best concrete mixer that meets your needs.
Advantages and disadvantages of a hand wheel versus a hand bar:
- easy emptying
- shifting of the lever forces
- easy adjustment of the degree of inclination of the drum
- needs more space for storage
Full metal wheels tend to rust
Almost all concrete mixers have two wheels. only a few brands or models are stationary. This allows you to easily move the mixer from A to B without having to carry the total weight of the concrete mixer.
Since a lot of weight is on the wheels, small cracks appear in the sheathing of the metal and expose the bare material. The first rust spots can be found in these unprotected areas after just a few months.
Pure plastic wheels are also attacked by cold weather. The material becomes porous and can break. Wheels with rims made of metal and rubberized tires are different. This type of wheels is more durable and they turn well even after months. So the mobility of the concrete mixer is still maintained.
Large footplate for stability
The footplate is parallel to the wheels. Although less weight rests on the footplate than on the tires, the plate still contributes to the stability of the concrete mixer.
If the footplates are too small, there is a possibility that the drum mixer will tip over while in use. Furthermore, the mixer can be stored more safely if he stands firmly and stably.
Therefore, we recommend you to choose a brand whose concrete mixer has a sufficiently large footplate. With this, you do not need additional stand protection and you can safely store the mixer in the garage, shed or garden.
With the right concrete mixer, building a house is fun. To ensure that this remains the case after construction, Stiftung Warentest examined residual debt insurance in more detail and found that complete protection is available for as little as €64 a year.
