因为诸如运输，泵送，浇注等的各类缘由，混凝土起首由油轮驱动器称重。品质查抄员根据油轮驱动器供给的称重列表和油轮的皮重列表计较残剩金额，而后根据不异的品级或较低品级。利用以下处置方式：
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）在统一级别利用。若是提早时候在2H之内，则与处置后的原始夹杂比比拟，水泥剂量应增添10-15kg/m3，并插手0.1％-0.3％。或间接下降强度程度，并恰当地增添调剂的夹杂物量。提早时候为2至4小时。处置后，水泥剂量应增添20至40kg/m3，并加夹杂物应增添0.4％至0.6％。或间接削减两个强度程度，并恰当增添调剂的夹杂物的量。
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）利用升级品级的利用必须基于用于升级混凝土和原始级混凝土的不异质料，并且仅合用于C40和C40以下的混凝土。在以上的根本上，削减一个强度程度停止处置。
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）提早时候跨越4小时，应报废或作为非承重低品级混凝土利用。若日均匀气温在5～20℃规模内，可按（1）中的环境增添处置0.5h。若日均匀气温低于5℃，可按（1）增添处置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，发明混凝土的坍落度达不到施工请求。若坍落度低于设想请求30-50mm，可按运输清单上的平方数，每侧加泵送剂0.5kg。比方货件体积是8m3，能够加0.5×8=4kg。若是用10kg的塑料桶装泵送剂，满桶11kg，约莫能够插手桶的2/5，而后用水管加水3-5s，将料斗中的泵送剂突入罐，启动罐疾速扭转3分钟，上车察看混凝土拌合物是不是适合，适合请求便可利用。
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期待较永劫候才起头利用资料或混凝土利用时候太长撞到柱子，混凝土在卸料槽中不活动时，应先预算罐内混凝土量，而后再预算罐内混凝土量。计较每1kg泵送剂的增添量。插手泵送剂后，根据第（4）条的请求停止加水、疾速扭转、察看等步骤。当利用局部资料并估量不精确的数目时，低估总比高估好。先少加一点，若是达不到请求，能够再加一点，到达请求。若是一次插手过量的泵送剂量，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.

厂家以为)在初凝期的混凝土中，因为温度高、运输间隔长、压抑时候长，混凝土的坍落度丧失比拟大。经实验可增添同类型的泵送剂或减水剂。但增添的总量和之前增添的总量不应跨越外加剂最大量的20%。应逐步增添，先少增添。搅拌后，打金鱼
必须疾速动弹2分钟摆布，并丈量坍落度适合请求。运至现场的混凝土不能当即卸货，卸货前应敏捷动弹运输车2分钟，以保障坍落度和品质。跨越初凝时候的混凝土应抛弃，不能反复利用。混凝土搅拌站浇筑前的障碍时候越长，混凝土强度丧失越严峻，应引发充足的正视。
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.
