我们都希望使用的混凝土的质量是非常好的,但是有很多因素影响着自动上料混凝土搅拌机的产品质量,都有哪些因素呢?
We all hope that the quality of concrete used is very good, but there are many factors that affect the product quality of automatic feeding concrete mixer. What are the factors?
一、原材料质量的选择准确:
1、 The selection of raw material quality is accurate
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: 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.
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: sampling inspection must be carried out for cement entering the site according to the regulations. Standard consistency and temperature test shall be carried out 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 index tests shall be continued. The cement that fails to pass the inspection is not allowed to enter the site. It is strictly forbidden to directly use the non digested hot cement in the project. The used cement should be traced and the "cement use traceability table" should be filled in.
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 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.
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 indicated on the package of admixtures at obvious positions: product name, model, net content or volume, name of manufacturer, date of production and factory number; whether the contents marked on the package are consistent with the product manual and certificate provided by the manufacturer; Whether the liquid admixture precipitates precipitates and whether it exceeds the validity period.
二、混凝土的配合比要正确。
2、 The mix proportion of concrete should be correct.
三、搅拌站中的称量系统要精确。
3、 The weighing system in the mixing plant should be accurate.
