由于諸如運(yùn)輸，泵送，澆注等的各種原因，混凝土首先由油輪驅(qū)動(dòng)器稱重。質(zhì)量檢查員根據(jù)油輪驅(qū)動(dòng)器提供的稱重列表和油輪的皮重列表計(jì)算剩余金額，然后根據(jù)相同的等級(jí)或較低等級(jí)。使用以下處理方法：

　　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）在同一級(jí)別使用。如果延遲時(shí)間在2H以內(nèi)，則與處理后的原始混合比相比，水泥劑量應(yīng)增加10-15kg/m3，并加入0.1％-0.3％。或直接降低強(qiáng)度水平，并適當(dāng)?shù)卦黾诱{(diào)整的混合物量。延遲時(shí)間為2至4小時(shí)。處理后，水泥劑量應(yīng)增加20至40kg/m3，并加混合物應(yīng)增加0.4％至0.6％?；蛑苯訙p少兩個(gè)強(qiáng)度水平，并適當(dāng)增加調(diào)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.

　?。?）使用降級(jí)等級(jí)的使用必須基于用于降級(jí)混凝土和原始級(jí)混凝土的相同原料，并且僅適用于C40和C40以下的混凝土。在以上的基礎(chǔ)上，減少一個(gè)強(qiáng)度水平進(jìn)行處理。

　　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.

　?。?）延遲時(shí)間超過4小時(shí)，應(yīng)報(bào)廢或作為非承重低等級(jí)混凝土使用。若日平均氣溫在5～20℃范圍內(nèi)，可按（1）中的情況增加處理0.5h。若日平均氣溫低于5℃，可按（1）增加處理1小時(shí)。

　　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)混凝土運(yùn)往施工現(xiàn)場時(shí)，發(fā)現(xiàn)混凝土的坍落度達(dá)不到施工要求。若坍落度低于設(shè)計(jì)要求30-50mm，可按運(yùn)輸清單上的平方數(shù)，每側(cè)加泵送劑0.5kg。比如貨件體積是8m3，可以加0.5×8=4kg。如果用10kg的塑料桶裝泵送劑，滿桶11kg，大約可以加入桶的2/5，然后用水管加水3-5s，將料斗中的泵送劑沖入罐，啟動(dòng)罐快速旋轉(zhuǎn)3分鐘，上車觀察混凝土拌合物是否合適，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.

　?。?）當(dāng)混凝土送至施工現(xiàn)場等待較長時(shí)間才開始使用材料或混凝土使用時(shí)間過長撞到柱子，混凝土在卸料槽中不流動(dòng)時(shí)，應(yīng)先估算罐內(nèi)混凝土量，然后再估算罐內(nèi)混凝土量。計(jì)算每1kg泵送劑的添加量。加入泵送劑后，按照第（4）條的要求進(jìn)行加水、快速旋轉(zhuǎn)、觀察等步驟。當(dāng)使用部分材料并估計(jì)不準(zhǔn)確的數(shù)量時(shí)，低估總比高估好。先少加一點(diǎn)，如果達(dá)不到要求，可以再加一點(diǎn)，達(dá)到要求。如果一次加入過多的泵送劑量，混凝土拌合物的坍落度太大，混凝土就會(huì)緩凝。

　　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）混凝土攪拌車廠家認(rèn)為)在初凝期的混凝土中，由于溫度高、運(yùn)輸距離長、壓制時(shí)間長，混凝土的坍落度損失比較大。經(jīng)試驗(yàn)可添加同類型的泵送劑或減水劑。但添加的總量和之前添加的總量不應(yīng)超過外加劑最大量的20%。應(yīng)逐漸添加，先少添加。攪拌后，攪拌車必須快速轉(zhuǎn)動(dòng)2分鐘左右，并測量坍落度符合要求。運(yùn)至現(xiàn)場的混凝土不能立即卸貨，卸貨前應(yīng)迅速轉(zhuǎn)動(dòng)運(yùn)輸車2分鐘，以保證坍落度和質(zhì)量。超過初凝時(shí)間的混凝土應(yīng)丟棄，不能重復(fù)使用?；炷翑嚢枵緷仓暗耐r(shí)間越長，混凝土強(qiáng)度損失越嚴(yán)重，應(yīng)引起足夠的重視。

　　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.
