First of all, of course, the quality of raw materials for concrete production must be strictly controlled. Especially after changing cement manufacturers, or newly imported cement, samples need to be retained to test the performance of the cement. As for aggregates, the moisture content and mud content must also be strictly controlled.
In the production process, concrete needs to be produced in strict accordance with the mix ratio. The operator cannot change the amount of certain raw materials in the concrete at will. During transportation, no one can add water or other additives to the concrete at will to ensure the consistency of concrete quality.
Concrete segregation is a difficult problem to control, and the actual situation needs to be treated realistically. In the daily production process, the production process should be strictly followed. Analyze the possibility of problems from all aspects and solve them one by one.
