First of all, the concrete mix proportion should ensure that the concrete has good working performance, such as pumpability, large fluidity, self compacting and so on. It should meet the strength, durability and other special design requirements of engineering structures.

混凝土在配合比设计中要积极合理应用减水剂等混凝土外加剂，以减少混凝土用水量，降低水胶比，提高混凝土强度。在混凝土中适量掺加粉煤灰、矿粉等外掺料，取代部分水泥和部分细骨料，在保证混凝土强度等级与工作性能要求下，可以显着提高混凝土的密实性，增加对钢筋的保护作用，同时降低混凝土经济成本。

In the mix proportion design of concrete, water reducing agent and other concrete admixtures should be actively and reasonably used to reduce the water consumption of concrete, reduce the water binder ratio and improve the concrete strength. Adding high-quality fly ash, mineral powder and other admixtures in concrete to replace part of cement and part of fine aggregate can significantly improve the compactness of concrete, increase the protection of reinforcement and reduce the economic cost of concrete.

其次，中科搅拌一体车原材料的管理要加强，砂、石料场要有良好的排水设施，以免底部积水。水泥、粉煤灰等粉料仓要有防潮、防雨措施。砂石料按品种、规格分隔堆放，避免混料。各种材料要标识清楚，特别是水泥、粉煤灰筒仓、外加剂贮存仓等进料口要加盖标识，专人管理，以防止进错料或受污染。

Secondly, the management of raw materials for the Zhongke mixer truck should be strengthened, and the sand and stone yards should have good drainage facilities to avoid water accumulation at the bottom. Moisture proof and rainproof measures shall be taken for cement, fly ash and other powder silos. Sand and stone materials shall be stacked separately according to varieties and specifications to avoid mixing. All kinds of materials should be clearly marked, especially the cement, fly ash silo, additive storage bin and other feeding outlets should be marked and managed by special personnel to prevent wrong feeding or contamination.

中科搅拌一体车能够加快施工进度、减少环境污染、改善施工条件、提高工程质量和节约材料成本。但是，全自动上料搅拌一体车的质量控制也是不可遗漏的要点。

It can speed up construction progress, reduce environmental pollution, improve construction conditions, improve project quality and save material cost. However, the quality control of the automatic feeding and mixing vehicle is also an important point.

全自动上料搅拌一体车控制质量的方法就是上面这些，希望现在建的各大工程都能保质保量的完成。

The above are the methods for controlling the quality of the fully automatic feeding and mixing vehicle. I hope that the major projects under construction can be completed with both quality and quantity.

为中科搅拌一体车选择的发动机一定要马力足，因为它要带动取力器、液压油泵、减速机来进行搅拌罐的运作。另一方面还要提供给底盘动力，马力不足是不行的。

The engine selected for the Zhongke mixer truck must have sufficient horsepower, because it needs to drive the power take-off, hydraulic oil pump and reducer to operate the mixing tank. On the other hand, it is necessary to provide the chassis with power, which is not enough.

变速箱这里陕齿法士特的，在国内到处可以看到它的厂房和变速箱物流运输车;小型混凝土搅拌车选发动机马力可以稍小一点，因为工作强度没那么大，够用就行，但是不能太小，太小买到手里一样不省油、耽误事

Shaanxi fast is recommended for the gearbox, and its factories and gearbox logistics trucks can be seen everywhere in China. The engine horsepower of small concrete mixer truck can be slightly smaller, because the working intensity is not so strong, it is enough to use it, but it can not be too small. If it is too small, it will not save fuel and delay things
