Experience and Suggestions on Quality Control of Mixing Plants

Concrete quality inspection is indispensable in the quality management and control of concrete and is the main means to ensure the quality of concrete. Throughout the entire process of concrete production, transportation and construction, it plays an indispensable role. Its main functions are as follows:

1. Strictly control the five key points and supervise the three prohibitions: namely, the inspection of raw materials, the design of mix proportions, the measurement, the mixing time of concrete, and the slump and strength. Substandard materials are not allowed to be used, equipment with inaccurate measurement is not allowed to be produced, and substandard concrete is not allowed to leave the factory to ensure that the concrete meets the quality requirements.

2. Samples should be randomly taken strictly in accordance with the regulations, test blocks should be made, and reports should be issued truthfully to truly achieve the purpose of guiding production.

3. Strengthen pre-control to prevent quality accidents. Through quality inspection of raw materials and fresh concrete and quality supervision throughout the production process, promptly grasp the quality dynamics of concrete, promptly identify problems, and take timely measures to handle them to prevent engineering quality accidents and keep the quality of concrete in a stable state.

4. Feedback information: Through the analysis and organization of inspection data, the quality status and variation patterns of concrete can be grasped, providing necessary information and basis for improving the concrete mix proportion design, ensuring concrete quality, making full use of admixtures and admixtures, reducing costs, and strengthening management.

5. Strengthen quality training to enhance the technical proficiency and quality awareness of operators, increase their sense of responsibility, and ensure the quality of concrete is up to standard. Regularly conducting targeted technical training for the technicians and operators of concrete mixing plants will undoubtedly have a relatively obvious effect on cost savings, efficiency improvement and further ensuring the quality of concrete.
