Quick loading and unloading is the key to prevent concrete from sticking to the tank!
1、 Bring some spare water reducing agents with you
Superplasticizer is a kind of concrete admixture that can reduce the mixing water volume under the condition of maintaining the constant slump of concrete. It can be carried with the vehicle and can adjust the concrete well. However, when adding water reducing agent, we must remember that people from the laboratory of commercial concrete station are present, otherwise the quality and strength of concrete are not enough, and the consequences will be very serious.
2、 Return to the station to check the water volume in the water storage tank
When returning to the station after unloading, check the amount of water in the water storage tank to keep the water in the tank full at any time for emergencies.
3、 Check the concrete quality before leaving the station
The quality of each truck of concrete may change due to different raw materials. When loading concrete and leaving the site, be sure to check the slump and workability of concrete in the tank, and be careful of early setting of concrete and segregation and precipitation of concrete.
4、 Minimize vehicle travel time
The concrete transportation distance is generally within a radius of 20km. The driving route and vehicle performance shall be planned before driving to minimize the driving time of vehicles on the road.
5、 Under special circumstances, in order to reduce the loss, unload the material first
In case of failure to unload for a long time due to human or irresistible factors, check the concrete in the tank at any time. Once it is found that the concrete begins to set. Unloading shall be carried out immediately to prevent the whole condensate tank from being scrapped. (the price of 12 m3 tanks on the market is about 80000, excluding labor and delay costs.)
Don't be afraid of trouble and try to clean it at any time.
