1. Bring water reducing agent with the car
Superplasticizer is a kind of concrete admixture which can reduce the amount of mixing water under the condition of maintaining the same slump of concrete. It can be carried with the car and can adjust the concrete well. However, when adding superplasticizer, we must remember that there are people in the laboratory of commercial concrete station, otherwise the concrete quality and strength are not enough, and the driver will bear the consequences.
2. Return to the factory to check the water quantity in the tank
Every time you return to the station after completing the task, check the water quantity in the water storage tank. It's better to keep the water in the tank full at any time in case of emergency.
3. Check the concrete quality before leaving the factory
The quality of each plate of concrete may change due to different raw materials. When loading the concrete 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 and layered precipitation of the concrete.
4. Reduce vehicle travel time
The concrete transportation distance is generally within the range of 30km in diameter. Before driving, the route and vehicle traffic conditions should be planned to minimize the time of vehicles on the road.
5. Reduce loss and discharge first
In case of failure to unload for a long time due to human factors or irresistible factors, the concrete condition in the tank should be checked at any time. Once it is found that the concrete begins to set. Discharge immediately after reporting to the person in charge to prevent the whole tank from being scrapped. It is understood that the price of 12 square tanks on the market is about 80000, excluding labor and work delay costs.
