1、 Take some spare water reducing agent with the vehicle
Water reducing agent is a kind of concrete admixture that can reduce the mixing water consumption under the condition of maintaining the constant concrete slump. It is carried with the vehicle and can adjust the concrete well. However, when adding water reducing agent, be sure to remember that there are people in the laboratory of the commercial concrete station, otherwise the concrete quality and strength 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
Every time when the vehicle is unloaded and returns to the station, the water volume in the water storage tank shall be checked to ensure that the water in the tank is always full for emergency. Self feeding mixer truck
3、 Check the concrete quality before leaving the station
The quality of each truck of concrete may change due to different raw materials. When the concrete is loaded and leaving the site, the slump and workability of the concrete in the tank must be checked, and care must be taken for the early setting and segregation of the concrete.
4、 Minimize the time the vehicle travels
The concrete transportation distance is generally within the radius of 20km. Before driving, the driving route and vehicle performance shall be planned to minimize the driving time of vehicles on the road. Self feeding mixer truck
5、 Under special circumstances, discharge materials first to reduce losses
If it is impossible to unload materials for a long time due to man-made or irresistible factors, the concrete in the tank shall be checked at any time. Once it is found that the concrete starts to set. Unloading shall be carried out immediately to prevent the whole tank from being scrapped.
