哪些因素會影響自上料攪拌車的產品質量？
有很多因素影響著自上料攪拌車的產品質量，都有哪些因素？
There are many factors that affect the product quality of self loading mixer. What are the factors?
一、原材料質量的選擇準確：
1、 Accurate selection of raw material quality:
1、骨料：粗細骨料進場必須按規定進行抽樣檢驗，檢驗合格方可使用。粗骨料應選用級配合理、粒形良好、質地均勻堅固的碎石或碎卵石，粗骨料各種指標應滿足相關標準規范的要求;控制泥含量和泥塊含量，及時進行檢測，經檢驗不合格的嚴禁進場卸車。
1. Aggregate: the coarse and fine aggregate must be sampled and inspected according to the regulations before being used. The coarse aggregate shall be gravel or crushed pebble with reasonable gradation, good grain shape, uniform and firm texture, and various indexes of coarse aggregate shall meet the requirements of relevant standards and specifications; the content of mud and mud lump shall be controlled, and the inspection shall be carried out in time, and the unqualified ones shall not be allowed to enter the site for unloading.
2、水泥：水泥進場必須按規定進行抽樣檢驗，每批進場的水泥均要求及時進行標準稠度與溫度測試，對質量存有懷疑的嚴禁入倉，并繼續進行其他指標測試，經檢驗不合格的水泥嚴禁進場。嚴禁未經消解的熱水泥直接使用于工程，對于已使用的水泥要進行追溯，并填制"水泥使用追溯表"。
2. Cement: the cement must be sampled and inspected according to the regulations when entering the site. The standard consistency and temperature of each batch of cement entering the site are required to be tested in time. If there is doubt about the quality, it is strictly forbidden to enter the warehouse, and other index tests shall be continued. The unqualified cement after inspection is strictly forbidden to enter the site. It is strictly forbidden to use the undigested hot cement directly in the project, trace the used cement, and fill in the "cement use traceability table".
3、礦物外摻料:根據有關標準規范的要求進行檢測。試驗室應隨時掌握礦物外摻料的質量變化情況，礦物摻料進場時，必須進行需水量比、燒失量、細度檢測，經檢驗合格的產品方可入庫;并注意與前期試驗結果進行對比，以判定質量的波動情況，確保工程質量。
3. Mineral admixtures: tested according to the requirements of relevant standards and specifications. The laboratory shall keep abreast of the quality changes of mineral admixtures at any time. When the mineral admixtures enter the site, the water demand ratio, loss on ignition and fineness must be tested, and the products that pass the inspection can be put into the warehouse. Attention shall be paid to the comparison with the previous test results to determine the quality fluctuation and ensure the project quality.
4、外加劑:外加劑進場時應加強檢查、檢測，檢查外加劑的包裝上是否在明顯位置上注明以下內容：產品名稱、型號、凈含量或體積、生產廠名、生產日期及出廠編號;檢查包裝物所標明的內容是否與生產廠家提供的產品說明書、合格證相符;液體外加劑是否析出沉淀物，是否超過有效期。
4. Admixtures: when admixtures enter the site, inspection and testing shall be strengthened to check whether the following contents are clearly indicated on the package of admixtures: product name, model, net content or volume, manufacturer name, production date and factory number; whether the contents indicated on the package are consistent with the product instructions and certificates provided by the manufacturer; Whether the liquid admixtures precipitate and exceed the validity period.
二、混凝土的配合比要正確。攪拌站中的稱量系統要精確。影響自上料攪拌車的產品質量的因素有很多，我們應該多多注意。
2、 The mix proportion of concrete should be correct. The weighing system in the mixing plant should be accurate. There are many factors affecting the product quality of self loading mixer, we should pay more attention to them.
