Description

Technical Field

[0002] In the production of cement paste or concrete, in order to ensure that the materials meet the relevant standards and specifications, sampling and characterization are required to verify whether their performance meets the use requirements, so as to ensure the quality of the project. Sampling is usually carried out when the mixing device is stopped. If you want to take slurry that has experienced different mixing times, you need to add materials multiple times and start timing from zero. Because if you add materials once but take materials multiple times, the mixing time cannot be accurately measured due to the shutdown and start of the mixing device. However, if you re-add materials every time you take materials at a fixed time and start timing from zero, it will lead to low efficiency and increased energy consumption.
