First of all, the choice of raw material quality is accurate.
1.骨料:粗骨料和粗骨料必须按照规定进行采样和测试。只能使用经过认证的产品。粗骨料应由砾石或破碎的小卵石组成,其等级应适度,质地良好且质地均匀。粗骨料指标必须符合相关标准和规范的要求,泥浆含量和泥浆含量必须及时控制和测试。如果检查失败,则严禁您进入卸货卡车。
1. Aggregate: coarse aggregate and coarse aggregate must be sampled and tested as required. Only use certified products. Coarse aggregate shall consist of gravel or crushed pebbles of moderate grade, good texture and uniform texture. The index of coarse aggregate must meet the requirements of relevant standards and specifications, and the mud content and mud content must be controlled and tested in time. If the inspection fails, you are not allowed to enter the unloading truck.
2.水泥:水泥必须按照规定取样。每批水泥应进行标准稠度和温度测试。如果您对质量有任何疑问,则严禁进入仓库并继续测试其他指标。严格禁止合格的水泥进入现场。严禁在项目中直接使用未加热的热水泥。

2. Cement: the cement must be sampled according to the regulations. Each batch of cement shall be tested for standard consistency and temperature. If you have any questions about the quality, do not enter the warehouse and continue to test other indicators. Qualified cement is strictly forbidden to enter the site. It is strictly forbidden to use unheated hot cement directly in the project.
3.矿物混合物:根据相关标准和规范进行测试。实验室需要跟上矿物混合物质量的变化。当矿物混合物进入现场时,必须测试其需水量,着火损失和细度。通过检查的产品可以存储,因此请注意初步测试。比较结果以确定质量波动并检查项目的质量。
3. Mineral mixture: test according to relevant standards and specifications. Laboratories need to keep up with changes in the quality of mineral mixtures. When the mineral mixture enters the site, its water demand, ignition loss and fineness must be tested. The products that pass the inspection can be stored, so please pay attention to the preliminary test. Compare the results to determine quality fluctuations and check the quality of the project.
4.外加剂:进入现场后检查并测试外加剂。检查混合包装是否标有:产品名称,型号,净含量或体积,制造商名称,生产日期,工厂编号。确保包装上的物品与产品规格和制造商提供的证书相符,并且沉积物未沉淀在液体混合物中且尚未过期。
4. Admixtures: check and test the admixtures after entering the site. Check whether the mixed package is marked with: product name, model, net content or volume, manufacturer name, production date, factory number. Ensure that the items on the package are in accordance with the product specifications and the manufacturer's certificate, and that the deposits have not settled in the liquid mixture and have not expired.
其次,具体的混合比例应正确。
Secondly, the specific mixing ratio should be correct.
第三,搅拌站称重系统必须准确。
Third, the weighing system of mixing station must be accurate.
