Zhongke concrete mixer manufacturers adhere to quality in production, because quality is the basis for the long-term survival of the mixing plant. Only by grasping the quality of concrete, can the quality of the entire infrastructure be guaranteed. Now, how to grasp the quality of concrete?

　　1. 严格控制原材料的进给误差，其中水泥、水、外加剂、粉煤灰的进给误差不超过±1%;砂石误差不超过±2%。

　　1. Strictly control the feed error of raw materials, in which the feed error of cement, water, admixture and fly ash shall not exceed ± 1%; the error of sand shall not exceed ± 2%.

　　2、严格按照原料进料顺序，进料顺序为:细骨料、水泥、矿物掺合料、掺合料、水、粗骨料。

　　2. In strict accordance with the order of raw material feeding, the feeding order is: fine aggregate, cement, mineral admixture, admixture, water, coarse aggregate.

　　3.搅拌时间:搅拌时，先将细骨料、水泥、矿物掺合料、外加剂放入搅拌机内。搅拌均匀(30s)后，加入所需的水。各阶段搅拌时间不得少于30s，总搅拌时间不得少于2分钟或多于3分钟。

　　3. Mixing time: when mixing, first put fine aggregate, cement, mineral admixture and admixture into the mixer. After stirring evenly (30s), add the required water. The mixing time of each stage shall not be less than 30s, and the total mixing time shall not be less than 2 minutes or more than 3 minutes.

　　4. 混凝土运输过程中坍落度损失过大，不满足现场施工要求时，严禁向罐车加水，增加坍落度。

　　4. If the slump loss during the concrete transportation is too large to meet the site construction requirements, it is strictly prohibited to add water to the tank car to increase the slump.

　　5. 具体运输应指定专人测量和记录。，用搅拌站微机数量对计量进行封闭，并对计量数据进行归档。

　　5. Specific transportation shall be measured and recorded by specially assigned person. Finally, the computer quantity of the mixing station is used to close the metering and archive the metering data.
