1. Bring water reducer with the vehicle
Superplasticizer is a kind of concrete admixture which can reduce the mixing water under the condition of maintaining the concrete slump unchanged. It can be carried along with the vehicle and can adjust the concrete well. However, when adding water reducing agent, we must remember that there are people in the laboratory of commercial concrete station, otherwise the concrete quality strength is not enough, and the driver should bear the consequences.
2. Return to the factory to check the water volume in the tank
When returning to the station after completing the task, check the water volume in the water storage tank. It is better to keep the water in the water tank full at any time in case of emergency.
3. Check the concrete quality before leaving the factory
Due to the different raw materials, the quality of each plate of concrete will change. When loading and leaving the site, it is necessary to check the slump and workability of the concrete in the tank, and be careful of the early setting of the concrete and the layered precipitation of the concrete.
4. Reduce vehicle travel time
The concrete transportation distance is generally within the range of 30km in diameter. The route and vehicle traffic condition shall be planned before the vehicle is set out, so as to minimize the time of vehicles on the road.
5. Reduce loss and unload first
If human factors or irresistible factors lead to long time unable to unload, check the concrete condition in the tank at any time, once the concrete starts to set. Discharge immediately after reporting to the person in charge to prevent the whole tank from being scrapped. It is understood that the 12 square tank on the market is about 80000, regardless of labor and delay costs.
