What does the cement laboratory mainly do?

Work: It is specially used for standard curing of commercial concrete, concrete test blocks and cement test blocks at constant temperature and humidity.

The laboratory meets the latest national standards. It is widely used in highway traffic, railways, bridges, civil buildings, water conservancy, hydropower and scientific research units, and has great promotion value. This equipment is the most advanced standard curing equipment for concrete and cement on the market at present, and has passed the national high-tech appraisal. It is a key product recommended by the Research Institute of Building Science and the Testing Center of the Ministry of Communications.

Daily work of laboratory technicians in cement plant;

1. Production control: measure cement fineness, additive dosage, raw calcium oxide, iron oxide, etc.

2. Chemical analysis: composition inspection of incoming raw materials, complete analysis of raw materials and clinker, etc.

3. Physical inspection: physical index inspection of ground cement and ex-factory cement.

The drugs and reagents used in various tests and analysis in cement industry laboratories are mainly acid and alkali, EDTA and commonly used reagents, which are basically non-toxic. In the process of analysis and inspection, a small amount of slightly toxic gas will be produced.

Extended data:

Matters that laboratory personnel should pay attention to:

1, the operator should hold relevant certificates, and the general site laboratory should be equipped with 6 members from 2 departments, and more testers should be added if conditions permit. The test qualification of the test engineer shall cover all categories of the project.

2. Personnel shall be designated to take charge of special tests, mainly involving signature and test time. Special attention will be paid during the inspection. Personal energy is limited, and it is impossible to cover all exam categories. Serious fraud in the exam will lead to bad consequences such as disqualification.

3, personnel should establish files, including qualification certificates (mainly for the tester or testing engineer certificate), identity certificates, professional title certificates, academic certificates, resumes, and some should also have post contract documents and other materials.
