  影响混凝土搅拌机的因素有很多,今天中科搅拌车小编就带大家一起来了解下主要的几点影响因素,来看看吧。
  There are many factors that affect the concrete mixer. Today, we will take you to understand the main factors. Let's have a look.
  一、混凝土的配合比要正确;
  1、 The mix proportion of concrete should be correct;
  二、搅拌站中的称量系统要精确;
  2、 The weighing system in the mixing station should be accurate;
  三、原材料质量的选择准确。以下是对混凝土原材料选择控制要求:要从源头上把好水泥、粗细骨料、外加剂、矿物外掺料品质关,原材料品质要求在供货合同中明确。
  3、 The selection of raw material quality is accurate. The following are the control requirements for the selection of concrete raw materials: the quality of cement, coarse and fine aggregates, admixtures and mineral admixtures shall be well controlled from the source, and the quality requirements of raw materials shall be specified in the supply contract.
  1、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(如安定性)测试,经检验不合格的水泥严禁进场。严禁未经均化(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"。

  1. Cement: sampling inspection must be carried out for cement entering the site according to the regulations. Standard consistency and temperature test shall be conducted for each batch of cement entering the site in time. If there is any doubt about the quality, it is forbidden to enter the warehouse, and other indicators (such as stability) test shall be continued. The cement that fails to pass the inspection is not allowed to enter the site. Hot cement without homogenization (digestion) is strictly prohibited to be directly used in the project. The used cement shall be traced and the "cement use traceability table" shall be filled in.
  2、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。
  2. Aggregate: coarse and fine aggregate must be sampled and inspected according to the regulations, and can be used only after passing the inspection. The coarse aggregate shall be gravel or pebble with reasonable gradation, good grain shape and uniform and firm texture, and various indexes of coarse aggregate shall meet the requirements of relevant standards and specifications; the content of mud and clay block shall be controlled, and timely detection shall be carried out. The unqualified ones shall not enter the site for unloading.
  3、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(包括含量或浓度)、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。
  3. 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 (including content or concentration), manufacturer name, production date and factory number; whether the contents marked on the package are consistent with the product instructions and certificates provided by the manufacturer; Whether the liquid admixture precipitates precipitates and whether it exceeds the validity period.
  4、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。在矿物外掺料的使用过程中,应尽量确保外掺料的相对稳定性。应与物资部门进行沟通,确保对于同类别的外掺料,一个搅拌站应尽量使用同一厂家的商品。当无法满足要求时,试验部门应及时进行配合比调整,严禁矿物外掺料的混用。
  4. Mineral admixture: according to the requirements of relevant standards and specifications for testing. The laboratory should master the quality changes of mineral admixtures at any time. When mineral admixtures enter the site, water demand ratio, loss on ignition and fineness test must be carried out, and the qualified products can be put into the warehouse; and the comparison with the previous test results should be paid attention to determine the quality fluctuation and ensure the engineering quality. In the process of using mineral admixture, the relative stability of mineral admixture should be ensured as far as possible. Communicate with the material department to ensure that for the same kind of admixture, one mixing plant should use the same manufacturer's products as far as possible. When the requirements can not be met, the test department should adjust the mix proportion in time, and it is forbidden to mix mineral admixture.
  5、搅拌站材料员要及时关注库存料的情况,并要有预见性及忧患意识,积极组织备料,避免出现停工待料,特别要关注散装水泥的结存。对库存的物资要挂牌标识,随时保证现场材料的堆码,严格按分仓进行原材料的存放。
  5. The materialman of the mixing plant should pay attention to the stock situation in time, have the foresight and the sense of worry, actively organize the preparation of materials, avoid the occurrence of shutdown and waiting for materials, and pay special attention to the balance of bulk cement. The materials in stock shall be marked with tags to ensure the stacking of materials on site at any time, and the raw materials shall be stored strictly according to different warehouses.
