What is a concrete mixer and what is its use?

study time 1 minute

1. Hand mixer (traditional): Suitable for small projects, limited foundations or repairs. 

3. Ground and aerial concrete mixers: used in bridge, dam and high-rise building projects.

### Basic concreting steps

1. Substrate preparation: cleaning the molds, wetting the surface and controlling the temperature. 

2. Production and transportation of concrete: respecting the allowed transportation time (maximum 90 minutes). 

3. Pouring concrete into the mold: in layers of 30 to 50 cm. 

5. Curing: maintaining moisture for at least 7 days to prevent cracking and flaking of the surface.

### Important technical points in concreting

- Use of standard reinforcing wire to stabilize the bars. 

- Concrete temperature control below 30 degrees Celsius in summer. 

- Avoid adding extra water to increase efficiency. 

- Selection of concrete lubricant (Superplasticizer) in precise structural projects.

### The difference between traditional and machine concrete pouring

| Feature | Traditional concrete mixer Machine concrete mixer |

| Execution speed down | Very high |

| Accuracy and density Average | high and uniform |

| Initial cost less | more |

| Energy saving does not have has |

| Application | Small projects Industrial and construction projects

### Choosing the right concrete mixer

Choosing the type of device and concreting method depends on factors such as project volume, structure type, location and implementation schedule. It is recommended to use fixed or rigged concrete pump systems for tall structures and ground mixers for wide foundations.

### Summary

Concreting plays a vital role in ensuring the quality and longevity of the structure. Paying attention to the type of device, concrete composition, execution time and correct processing are considered to be the most important parameters for the success of construction projects.
