1. Carry water reducing agent

减水剂是一种混凝土外加剂，可以减少用于混合的水量，同时保持混凝土的塌陷。它可以随混凝土自上料搅拌车携带，并且可以很好地调整混凝土。但是，参加减水剂时，请记住上野站的实验室里有人。否则，混凝土质量不足，驾驶员必须承受后果。

Superplasticizer is a kind of concrete admixture, which can reduce the amount of water used for mixing and maintain the collapse of concrete. It can be carried with the concrete from the loading mixer and can adjust the concrete well. However, when participating in water reducer, please remember that there is someone in the laboratory of Ueno station. Otherwise, the concrete quality is insufficient, and the driver must bear the consequences.

2.返回工厂检查水箱中的水量

2. Return to the factory to check the water volume in the water tank

每次下火车返回车站时，请检查混凝土自上料搅拌车的储水箱中的水量。紧急情况下，请始终保持水箱充满。

Every time you get off the train and return to the station, please check the water volume of the concrete from the water storage tank of the loading mixer. Always keep the water tank full in case of emergency.

3.出厂前检查混凝土质量

3. Check the concrete quality before delivery

不同的材料可以改变每个混凝土卷轴的质量。如果在安装后留下混凝土，请检查储罐中混凝土的坍落度和易用性，并注意混凝土的过早硬化和分层沉降。

Different materials can change the quality of each concrete reel. If concrete is left behind after installation, check the slump and ease of use of the concrete in the tank, and pay attention to premature hardening and delamination settlement of the concrete.

4.减少混凝土自上料搅拌车行驶时间

4. Reduce the driving time of concrete self loading mixer

混凝土的运输距离通常直径在30以内。在离开汽车之前，请规划道路和车辆的交通状况，并尝试减少小型混凝土搅拌机在路上的时间。

The transportation distance of concrete is usually less than 30 km in diameter. Before you leave the car, plan the road and vehicle traffic conditions and try to reduce the time the small concrete mixer is on the road.

5.减少损失并优先卸载

5. Reduce losses and give priority to unloading

如果长时间遇到人为或非电阻性因素并导致卸载，则应始终检查混凝土自上料搅拌罐中混凝土的状况。如果发现混凝土开始变硬。请尽快向负责人报告，以免整个箱子被丢弃。

If human or non resistive factors are encountered for a long time and lead to unloading, the condition of concrete from the loading mixing tank shall be always checked. If it is found that the concrete begins to harden. Please report to the person in charge as soon as possible so as not to discard the whole box.
