The essential elements of quality control in concrete mixing plant

Introduction: Concrete mixing plant is a concrete production facility. It is composed of concrete mixer, batching machine, weighing system, material conveying system and fully automatic control system. Each part complements each other and cooperates with each other to keep the concrete mixing station in an orderly and efficient manner. Run to meet the needs of the project.

What are the necessary elements for the quality control of a concrete mixing plant?

First, use qualified raw materials

The raw materials of the concrete mixing station are generally: gravel, cement, admixtures, etc. The manufacturer should provide the product certification when purchasing. The material room of the concrete mixing plant is sampled for inspection. All raw materials must be inspected before being used, and the unqualified raw materials will be cleaned out in time.

Second, in strict accordance with the mixing ratio to ingredients

The concrete mixing station must strictly mix according to the mix ratio, in principle, manual operation of the valve is not allowed. The input and change of the mix ratio can only be performed by the concrete mixing station test personnel, and no one else can adjust it. The maintenance personnel of the concrete mixing station shall strengthen the overhaul and maintenance of the mixing equipment and regularly measure the measurement timing device.

Third, strict inspection of the concrete and then the factory

For concrete of different specifications produced by the concrete mixing plant, the test personnel shall check the quality of each concrete before leaving the station, including concrete slump, gas content, bleeding rate, water-cement ratio, etc. Only after leaving the station, if the performance of the mixture cannot meet the requirements, it shall be handled in time. For the concrete that arrived at the site, the testers in the work area shall also perform the same test. After the indicators are qualified, they can enter the mold and feed back information to the laboratory of the mixing plant in time.

The quality of the concrete affects the quality of the entire project. Therefore, only by grasping the quality control of the concrete mixer, the concrete mixing plant can effectively grasp the quality of the concrete.
