I saw a video on YouTube - man, alone, with the help of the two-spindle mixer, kneaded concrete and two days filled strip foundation. I thought maybe this is - advertising tool? The builder claims that the mixer knead more convenient than the mixer. The issue date for me. I kneaded concrete into the concrete mixer. One seriously. We have to raise the bucket. Download pear. I took a concrete mixer for hire. His store anywhere. A mixer can knead concrete on-site fill. It weighs a little. Prompt - it's real, if small volumes knead? Maybe someone has already used a mixer? The tool does not break?

I think that the tools should be used exactly as prescribed. The mixer is needed to stop the plaster and glue mixture and concrete mixer truck. The weak point of the mixer - attachments. At the pavilion on a heavy concrete with crushed stone, the blade can come off, or he sognotsya.

Compare the price of a normal mixer and concrete mixers. The difference is small. I think health is more expensive! Using a mixer, you can work together. One is sand and gravel, the second keeps track of the batch. Mixer you are working alone. On it, oh what forces are needed. Quickly get tired. My mixer for 10 years, and it has long paid for itself.

Now listen to the views of those members FORUMHOUSE, who really kneaded concrete mixer.

Bath1

I am filled with a mixer strip foundation for the fence. Tape length 25 m cross section -. 200x300 mm. Another concreted jumper to 5 m below the gate and gate. In my experience, more than not you get tired of working with a mixer, and from zakidyvaniya sand, cement and gravel, concrete and pulling. But also need to throw the ingredients into the mixer. It even after washing is necessary, and the mixer spun in the water and went home. Pour blender foundation under the house, I certainly would not dare, but in small quantities, it is quite suitable option.

Mixture Bath1 I prepared as follows:

• First, it prevented the dry sand with cement.
• Then I add water. The consistency of the mixture as sour cream.
• Then 3 slung gravel bucket. Promeshal mixture. Then he added another 1.5 rubble bucket.

I interfered Duplex mixer concrete in a cast-iron bath. Two spindles are better than one. Torque is extinguished and, in the case of a wedge, not wound on the instrument. Casting a cement, sand, gravel fractions 5-20. Meshal ten minutes and 200 liters of ready mixture. Not to say it's easy, but not difficult. Crushed between the screws is not stuck. The tool is not broken.

Shorter. I listened to everyone, and also decided to knead concrete mixer. I report. Knead about 1.5 cube of concrete under the pier foundation. The mixture is stiff. Ratio: 1 part cement, 3 parts sand, 4 parts of gravel and 0.75 liters of water. Interfered in the trough 100 liters. The day did 5-7 batches. More could not. Very tired hands, especially hands. Not to say that I am a weak, but it turns the load on the joints decent. Crushed between fractions 5-20 corollas not stuck. The tool is also survived. Verdict: The method is suitable for small volumes for occasional work.

I wonder whether it is possible to fill with a mixer volume of more? Construction experience FORUMHOUSE user says: "Yes."

I helpers poured concrete mixer 4 cube. Worked 4 people - two men and two women. Women were applied to buckets-rich cement, sand-gravel mixture. One man kneads. The second carries buckets, and then the two of us throw out the mixture into the mold. Mixing ratio: 1 bucket of cement, sand bucket 1, 3 bucket OPGS, 0.7 buckets of water. Total made 115 mixes with smoke breaks. More rain was. The old tub is also sprung a leak. We repaired it. Bottom line: starting at 10 am, finished in the eleventh hour of the evening. Then another, and in the morning Domes bit. The back is tired, but once you get used to keep the mixer without inclination, with legs wide apart, no fatigue. If it began to interfere at 7 am, there were 3 men, and not women, not the rain, and the tub is not sprung a leak, I think, would have coped until 6pm.Mixer kneads the mixture quickly. The main fatigue - by dragging buckets SPLG through formwork and lifting buckets to die and fall to the level of the formwork concrete.

Tips Veter753 to work with a mixer at a concrete mix:

• First load water, cement and sand.
• Knead the mixture to the state of cream.
• Add 2 SPLG buckets.
• Knead the mixture until a homogeneous gray color.
• Add another bucket SPLG.
• Once again knead uniformly.

Concrete ready.

If the mixer to keep the same place, it is not peremesit mixture as it will be mixed in one place. For good mixing concrete mixer mixer need to drive in a circle, and zigzags to the left and to the right.

The two of us, for 4 days, poured concrete mixer 17 cubes. Monoliths plate. Concrete kneaded in the bath. Put it on the inside formwork and rebar were inverted after each batch. Tired of course, but also with concrete mixer would be tired too. I liked to work with a mixer. It prevents fast. Hands turns, the back does not hurt, although churned one-spindle tool. Longer get tired from the tray of sand, cement and gravel.

Mixing concrete concrete mixer and blender: similarities and differences

I'm wondering: pear concrete mixer rotates at 30 rev / min, and the mixer produces up to 600 rev / min. It somehow affects the quality of the mixture?

Despite the difference in the number of rotations of units, the output you get concrete = high quality. The main difference is that the gravitational rotating mixer with a mixture of pear and mixer at work, on the contrary, the capacity is fixed and the mixing is carried out rotating the crown. Why is the number of mixers and mixer speed are different?

If you increase the speed of pear, then under the influence of centrifugal force, the ingredients just stick to the walls of the drum, and the mixing process is not. If, on the contrary, reduce the speed, the ingredients will slide on the bottom plane of pears, practically climbing up. the mixing process is not. Therefore 25-30 rev / min are optimal for concrete mixers. If the mixer to increase the number of revolutions, the mixture will be splashes out of the vessel. If lower speed, then interfere with the mixture will be very long.

Another point. The mixer is difficult to interfere with m. N. hard concrete with low water-cement ratio. Such concrete interfere in the compulsory mixer, and they are expensive, or alternatively - a mixer.

I'm in the way heavy concrete mixer. I work alone, so have developed an optimal technique. Tool - mixer capacity of 1.4 kW. Two spindles. Prevents concrete in round plastic tub 80 liters. It is the optimum volume. If you take more - nepromes. For large volume at a time do not chase! Nuisance 1-2-4 10 liter buckets per batch. Compared with the concrete mixer, paving speed has almost doubled. And: stirrer crowns, depending on the configuration, may pull the solution either upwards or downwards. Concrete buy a beater that he rowed up, and you have drawn down. So work is more convenient than trying to push through the concrete mixer. Incidentally, the back does not hurt, do not hand turns.

But my experience of mixing concrete mixer.

Pros and cons of mixing concrete with a drill-mixer

Let's sum up. Pros mixing concrete mixer:

• Mixer capacity 1-1.5 kW worth 4500 - 6000 thousand. rubles. The price of high-quality concrete mixer,volume of 160-180 liters starts at 10 thousand. rub.
• Instead of a mixer, you can buy a drill-mixer, and get the tool, "two in one", which can knead the mortars and concrete, as well as drilling holes in metal and wood.

• In contrast to the mixers, mixer, easy and does not take up much space. At the end of it, you can throw in a car trunk or hide in the shed.
• Mixer prevents "hard" concrete.
• High-speed concrete mixing 1.5-2 cube.

Concrete mixer interfere in the old tub, a plastic tub or iron, or metallic barrel 200 liters, which has an upper cut portion so as to obtain a container volume of 120-130 liters. If disturb the concrete mixer in a square or rectangular tank rail without recesses, then the solution promeshaetsya corners and it will get the shovel.

Disadvantages of preparation of the concrete mixer:

• The complexity of a solution volume of more than 3 cubic meters. You will need helpers, porters sand and gravel.
• Dual work by manual priming and fall over the tub of the ingredients and the finished mixture, while the mixture from the mixer falls turning wheel pears.
• With the concrete mixer is physically easier to operate. The mixer will have to hold hands.

Homebrew note! Try to modify the mixer, turn it into a mini-compulsory mixer, based tool for mixing compounds and adhesives in the photo below. For example, take a frame for mounting on a metal drum of 200 liters. Weld it with the steering wheel axis, and the mixer fix on a rotary support and lower crowns of the nozzle into the tank. Moreover, the axis of the shaft of the mixer should not take place strictly in the middle of the barrel, and closer to the edge of it. Cast in the container for the ingredients of concrete mortar. After stirring the mixture concrete falls from the barrel into the mold or into a wheelbarrow. The cycle then repeats. Do you think the idea of ​​working?
