1、 Bring some spare water reducer with you
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 is not enough, the consequences will be very serious.
2、 Return to the station to check the water quantity in the water storage tank
Every time you return to the station after unloading, check the amount of water in the water storage tank. It is better to keep the water in the tank full at any time in case of emergency.
3、 Check the concrete quality before leaving the station
Because of the different raw materials, the concrete quality of each truck will change. When installing 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 segregation of the concrete.
4、 Minimize vehicle travel time
The concrete transportation distance is generally within the radius of 20 km. Before driving, plan the driving route and vehicle performance to minimize the driving time of vehicles on the road.
5、 In order to reduce the loss, discharge the material first under special circumstances
If it is impossible to unload for a long time due to man-made or irresistible factors, check the concrete condition in the tank at any time. Once it is found that the concrete begins to set. Unloading should be carried out immediately to prevent the whole tank from being scrapped.
