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划定停止采样和测试。只能利用颠末认证的产物。粗骨料应由砾石或破裂的小卵石构成，其品级应过度，质地杰出且质地平均。粗骨料目标必须合适相干标准和标准的请求，泥浆含量和泥浆含量必须实时节制和测试。若是查抄失利，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：水泥必须按照划定取样。每批水泥应停止标准稠度和温度测试。若是您对品德有任何疑难，则严禁进入堆栈并持续测试其余目标。严酷制止及格的水泥进入现场。严禁在名目中间接利用未加热的热水泥。
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.矿物夹杂物：按照相干标准和标准停止测试。尝试室须要跟上矿物夹杂物品德的变更。当矿物夹杂物进入现场时，必须测试其需水量，着火丧失和细度。经由进程查抄的产物能够存储，是以请注重开端测试。比拟成果以肯定品德动摇并查抄名目的品德。
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：进入现场后查抄并测试外加剂。查抄夹杂包装是不是标有：产物称号，型号，净含量或体积，制作商称号，出产日期，工场编号。确保包装上的物品与产物规格和制作商供给的证书合适，并且堆积物未积淀在液体夹杂物中且还没有过时。
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，详细的夹杂比例应精确。
Secondly, the specific mixing ratio should be correct.
第三，搅拌站称重体系必须精确。
Third, the weighing system of mixing station must be accurate.
