由于诸如运输，泵送，浇注等的各种原因，混凝土首先由油轮驱动器称重。质量检查员根据油轮驱动器提供的称重列表和油轮的皮重列表计算剩余金额，然后根据相同的等级或较低等级。使用以下处理方法：

　　For various reasons such as transportation, pumping, pouring, etc., the concrete is first weighed by the tanker driver. The quality inspector calculates the remaining amount based on the weighing list provided by the tanker driver and the tanker's tare list and then on the same grade or lower grade. Use the following processing methods:

　　（1）在同一级别使用。如果延迟时间在2H以内，则与处理后的原始混合比相比，水泥剂量应增加10-15kg/m3，并加入0.1％-0.3％。或直接降低强度水平，并适当地增加调整的混合物量。延迟时间为2至4小时。处理后，水泥剂量应增加20至40kg/m3，并加混合物应增加0.4％至0.6％。或直接减少两个强度水平，并适当增加调整的混合物的量。

　　Use at the same level. If the delay time is less than 2H, the cement dose should be increased by 10-15kg/m3 and added by 0.1-0.3% compared to the original mixture after treatment. Or directly reduce the strength level and appropriately increase the amount of the adjusted mixture. The delay is 2 to 4 hours. After treatment, the cement dose should be increased by 20 to 40kg/m3, and the mixture should be increased by 0.4% to 0.6%. Or simply reduce the two strength levels and appropriately increase the amount of the adjusted mixture.

　　（2）使用降级等级的使用必须基于用于降级混凝土和原始级混凝土的相同原料，并且仅适用于C40和C40以下的混凝土。在以上的基础上，减少一个强度水平进行处理。

　　The use of degraded grade must be based on the same raw materials used for degraded and original grade concrete and only apply to concrete below C40 and C40. On the basis of the above, reduce the intensity level for processing.

　　（3）延迟时间超过4小时，应报废或作为非承重低等级混凝土使用。若日平均气温在5～20℃范围内，可按（1）中的情况增加处理0.5h。若日平均气温低于5℃，可按（1）增加处理1小时。

　　If the delay time exceeds 4 hours, it should be scrapped or used as non-load-bearing low-grade concrete. If the average daily temperature is within the range of 5-20 ℃, the treatment can be increased by 0.5h as shown in (1). If the average daily temperature is less than 5℃, the treatment can be increased by 1 hour according to (1).

　　(4)混凝土运往施工现场时，发现混凝土的坍落度达不到施工要求。若坍落度低于设计要求30-50mm，可按运输清单上的平方数，每侧加泵送剂0.5kg。比如货件体积是8m3，可以加0.5×8=4kg。如果用10kg的塑料桶装泵送剂，满桶11kg，大约可以加入桶的2/5，然后用水管加水3-5s，将料斗中的泵送剂冲入罐，启动罐快速旋转3分钟，上车观察混凝土拌合物是否合适，符合要求即可使用。

　　When concrete is transported to the construction site, it is found that the slump of concrete cannot meet the construction requirements. If the slump is lower than the design requirements of 30-50mm, 0.5kg pumping agent can be added to each side according to the square number on the transportation list. For example, if the shipment volume is 8m3, 0.5×8=4kg can be added. If you use 10kg plastic bucket pumping agent, full bucket 11kg, about 2/5 can be added to the bucket, and then add water 3-5s with water pipe, the pumping agent in the hopper into the tank, start the tank quickly rotate for 3 minutes, get on the car to observe whether the concrete mixture is appropriate, can be used in accordance with the requirements.

　　（5）当混凝土送至施工现场等待较长时间才开始使用材料或混凝土使用时间过长撞到柱子，混凝土在卸料槽中不流动时，应先估算罐内混凝土量，然后再估算罐内混凝土量。计算每1kg泵送剂的添加量。加入泵送剂后，按照第（4）条的要求进行加水、快速旋转、观察等步骤。当使用部分材料并估计不准确的数量时，低估总比高估好。先少加一点，如果达不到要求，可以再加一点，达到要求。如果一次加入过多的泵送剂量，混凝土拌合物的坍落度太大，混凝土就会缓凝。

　　when the concrete is sent to the construction site to wait for a long time before the use of materials or concrete use time is too long to hit the column, concrete in the discharge tank does not flow, should first estimate the amount of concrete in the tank, and then estimate the amount of concrete in the tank. Calculate the amount of pumping agent per 1kg. After the pumping agent is added, water, rapid rotation, observation and other steps shall be carried out in accordance with the requirements of Article (4). When using partial materials and estimating the amount of inaccuracies, it is better to underestimate than to overestimate. Add a little bit less, and if you don't meet the requirements, you can add a little bit more to meet the requirements. If too much pumping dose is added at one time, the concrete mix will slump too much and the concrete will slow down.

　　(6）混凝土搅拌车厂家认为)在初凝期的混凝土中，由于温度高、运输距离长、压制时间长，混凝土的坍落度损失比较大。经试验可添加同类型的泵送剂或减水剂。但添加的总量和之前添加的总量不应超过外加剂最大量的20%。应逐渐添加，先少添加。搅拌后，搅拌车必须快速转动2分钟左右，并测量坍落度符合要求。运至现场的混凝土不能立即卸货，卸货前应迅速转动运输车2分钟，以保证坍落度和质量。超过初凝时间的混凝土应丢弃，不能重复使用。混凝土搅拌站浇筑前的停滞时间越长，混凝土强度损失越严重，应引起足够的重视。

　　in the initial setting period of concrete, due to high temperature, long transportation distance, long pressing time, concrete slump loss is relatively large. After the test can add the same type of pumping agent or water reducing agent. But the total amount added and the total amount previously added should not exceed 20% of the maximum amount of the admixture. It should be added gradually and less at first. After mixing, the mixing car must turn quickly for about 2 minutes, and measure slump to meet the requirements. The concrete transported to the site cannot be unloaded immediately. Before unloading, the transport truck should be quickly turned for 2 minutes to ensure slump and quality. Concrete beyond the initial setting time should be discarded, not reused. Concrete mixing station before pouring stagnation time is longer, concrete strength loss is more serious, should cause enough attention.
