1、 Bring some spare water reducer 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 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.

二、回站检查储水罐内的水量

2、 Return to the station to check the water quantity 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，更好让水罐中的水随时处于满罐的状态，以备不时之需。

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.

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。

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.

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 the radius of 20 km. Before driving, plan the driving route and vehicle performance 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、 In order to reduce the loss, discharge the material first under special circumstances

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。

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.
