Qualifications

Higher education without requirements for work experience or secondary specialized education and work experience as a laboratory technician or other engineering and technical positions for at least 3 years.

1. What is the name of your profession (position)?

My profession is simply called laboratory assistant.

2. What is your job and what are your responsibilities?

I work in the laboratory of a concrete plant at construction site, my responsibilities include testing product samples (concrete), testing materials (crushed stone, sand, water, additives), reporting results and experiments, document management in the laboratory - I make sure that all tests are done on time, correctly formatted and pinned to the right folder .

3. What education is required to get your position?

Better, of course, higher, but it is possible with an average.

4. Describe your working day.

Measure the temperature of materials before mixing them, prepare samples of finished products for testing (measure and weigh concrete cubes), test them (crash test in special apparatus, where the cubes are pressed by the press and count the load), enter the data into the system, process them and make a report on the corresponding batch of concrete.

5. How comfortable are your working conditions (all day outside, or in the office with a cup of coffee)?

Most of the day in the lab, sometimes outside.

6. What do you like most about your job?

Most of all I liked working with the system, analyzing data and compiling reports. Highly important work, I believe, because the strength of the entire building depends on the strength of concrete. And we have the opportunity, having analyzed all the initial data (temperature and composition of the material, the density of the raw concrete mix), to draw preliminary conclusions about the strength of the finished concrete.

7. What do you dislike most about your job?

Testing on the street - I'm afraid of the cold

8. If it's not a secret, what is your salary level (is it enough to write whether you are satisfied or not)?

The pay is high, of course. But the conditions are quite difficult - the working day is from 8 in the morning and sometimes until late in the evening, sometimes work outside in the cold.

9. Describe your team, what kind of people work with you?

The team at the construction site mainly consists of men, so the attitude towards us, girls, is very loyal and adequate. Protect us!

10. What human qualities do you think are most important in your business?

Attention and accuracy. A responsibility.

11. Work gives me additional opportunities (here everything that work gives you except money, from self-expression and communication with interesting people before being able to visit different countries).

Construction is often invested by foreign partners, which means the periodic presence of their representatives. So it turns out that on duty you have to communicate with people from different countries. I improved my English and gained experience of communicating not only with Americans and British, but also with Malaysians and Filipinos.

12. Do you have the opportunity to evaluate your work on a five-point scale, what grade would you give?

13. Why did you choose this job?

At first, of course, the main factor was the high pay and the opportunity to train in English language, well, and then the possibility of rapid career growth.

Construction is an area in which you can make a good career, so there is no need to be afraid of difficulties.

In the testing laboratory of our company "Aubrey" the following services are carried out to check the quality of concrete:

• It is possible to conclude an agreement, according to which the quality of the raw materials supplied for the manufacture of concrete will be checked by our specialists on a daily basis. In the laboratory, you can determine what the setting time of concrete will be, depending on the density of the cement mass. The grain composition of crushed stone and sand, their grinding density and purity will also be clarified. Separately for crushed stone, it will be possible to set its strength. The volume-bulk mass is also analyzed, first in a dry state, and then in a wet state.
• Our specialists will help to establish the frost resistance of concrete, as well as how waterproof it is.
• In the laboratory, you can determine the temperature of the concrete mixture, find out what will be its stratification and safety in the future. These indicators are affected by the density of the mixture, which can also be set before the start of construction work.
• Our concrete quality laboratory also tests the strength of samples, comparing them with the requirements of GOST.
• Specialists can create a unique concrete mix recipe that is ideal for the construction of your facility.

The laboratory stores samples from any batch of products that have already been sent to the consumer. At your request, laboratory analysis of concrete can be carried out directly at the construction site.

Every year, unique compositions of concrete mixtures are created that have not been used before, completely new areas of application are found for them. Depending on the specific construction object, the requirements for the properties of concrete will be completely different. The specialists of the Obrey laboratory undergo periodic training and exchange of experience with the best employees of research institutes, leading Russian and foreign companies. Based on the knowledge gained, we develop unique concrete compositions and are ready to share our experience with our customers.

We also conduct a classic concrete test, through which regular product quality control will be carried out, and buyers will be fully informed about the properties of a particular batch of concrete. When performing tests, the following is carried out:

• the activity of the cement is checked,
• concrete and mortar are tested for frost resistance,
• the degree of impermeability of concrete is determined,
• then it is checked in a non-destructive way how strong the concrete is.

Documents containing detailed test results and product characteristics will be attached to each batch of concrete. Also, buyers can contact the Aubrey laboratory in order to check samples of purchased concrete, after the analysis a detailed report will be provided.

Documents confirming the properties of concrete and mortar are attached to each batch of products. At the request of the buyers, the laboratory analyzes the samples and provides a detailed report. You can get acquainted with the prices of tests in the section.

Construction laboratory LLC "PSK Obrey" provides testing services building materials and inspection of reinforced concrete structures.
