1、 Bring some spare water reducing agents with you

减水剂是一种在维持混凝土坍落度不变的条件下，能减少拌合用水量的混凝土外加剂，随车携带，能对混凝土进行很好的调节。不过在加入减水剂的时候，一定要记得有商砼站化验室的人在场，否则混凝土质量强度不够，后果会很严重。

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.

二、回站检查储水罐内的水量

2、 Return to the station to check the water volume in the water storage tank

每次出车卸完料回到站内的时候，检查储水罐内的水量，确保让水罐中的水随时处于满罐的状态，以备不时之需。

When returning to the station after unloading, check the amount of water in the water storage tank to ensure that the water in the water tank is full at any time in case of emergency.

三、离站前检查混凝土质量

3、 Check the concrete quality before leaving the station

可能会因为原料的不同，每一车混凝土质量都会有变化。在装好混凝土离场时，一定要检查罐内混凝土的塌落度以及和易度，小心混凝土的提前凝结和混凝土离析沉淀。

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.

四、尽量减少车辆行驶的时间

4、 Minimize vehicle travel time

混凝土运输距离一般在半径20公里范围以内，出车之前规划好行车路线以及车辆性能情况，尽量减少车辆在路上的行驶时间。

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.

五、特殊情况为了减少损失先卸料

5、 Under special circumstances, in order to reduce the loss, unload the material first

如果遇人为或不可抗因素，导致长时间无法卸料的情况，应随时查看罐内混凝土情况，一旦发现混凝土开始凝结。应立刻进行卸料，以防整个罐体凝罐报废。

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.
