哪些因素会影响自上料搅拌车的产品质量？
有很多因素影响着自上料搅拌车的产品质量，都有哪些因素？
There are many factors that affect the product quality of self loading mixer. What are the factors?
一、原材料质量的选择准确：
1、 Accurate selection of raw material quality:
1、骨料：粗细骨料进场必须按规定进行抽样检验，检验合格方可使用。粗骨料应选用级配合理、粒形良好、质地均匀坚固的碎石或碎卵石，粗骨料各种指标应满足相关标准规范的要求;控制泥含量和泥块含量，及时进行检测，经检验不合格的严禁进场卸车。
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：水泥进场必须按规定进行抽样检验，每批进场的水泥均要求及时进行标准稠度与温度测试，对质量存有怀疑的严禁入仓，并继续进行其他指标测试，经检验不合格的水泥严禁进场。严禁未经消解的热水泥直接使用于工程，对于已使用的水泥要进行追溯，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、矿物外掺料:根据有关标准规范的要求进行检测。试验室应随时掌握矿物外掺料的质量变化情况，矿物掺料进场时，必须进行需水量比、烧失量、细度检测，经检验合格的产品方可入库;并注意与前期试验结果进行对比，以判定质量的波动情况，确保工程质量。
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、外加剂:外加剂进场时应加强检查、检测，检查外加剂的包装上是否在明显位置上注明以下内容：产品名称、型号、净含量或体积、生产厂名、生产日期及出厂编号;检查包装物所标明的内容是否与生产厂家提供的产品说明书、合格证相符;液体外加剂是否析出沉淀物，是否超过有效期。
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确。搅拌站中的称量系统要精确。影响自上料搅拌车的产品质量的因素有很多，我们应该多多注意。
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.
