Now there are many bean curd dregs projects. This kind of project is not only the loss of property, but also the risk of life. The bean curd dregs project is due to the poor quality of concrete, so how should we control the quality of the automatic feeding mixer?

　　，混凝土配合比要保证混凝土有良好的工作性能，比如可泵性、大流动性、自密实性等。要满足工程结构物强度、耐久性及其他特别设计要求。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。

　　First of all, the concrete mix proportion should ensure that the concrete has good working performance, such as pumpability, large fluidity, self compactness and so on. It shall meet the strength, durability and other special design requirements of engineering structures. In the mix design of concrete, concrete admixtures such as superplasticizer should be actively and reasonably applied to reduce the water consumption of concrete, reduce the water binder ratio and improve the strength of concrete. In order to ensure the strength grade and working performance of the concrete, it can significantly improve the compactness of the concrete, increase the protection effect on the reinforcement, and reduce the economic cost of the concrete.

　　其次，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 should be strengthened. Sand and stone yards should have good drainage facilities to avoid water accumulation at the bottom. Cement, fly ash and other powder silos shall be provided with moisture-proof and rainproof measures. Sand and stone materials shall be stacked separately according to varieties and specifications to avoid mixing. All kinds of materials shall be clearly identified, especially for the cement, fly ash silo, additive storage silo and other feeding ports, which shall be marked and managed by special personnel to prevent wrong feeding or pollution.

　　为了能够加快施工进度、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。    
　　In order to speed up construction progress, reduce environmental pollution, improve construction conditions, improve project quality and save material costs. However, the quality control of the full-automatic feeding and mixing integrated vehicle is also an indispensable point.

　　自动上料搅拌机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。

　　This is the way to control the quality of the automatic feeding mixer. I hope that the major projects built now can be completed with quality and quantity guaranteed.

　　为自动上料搅拌机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 automatic feeding mixer must have sufficient horsepower, because it must drive the power take-off, hydraulic oil pump and reducer to operate the mixing tank. On the other hand, we need to provide power for the chassis. It's not enough horsepower.

　　变速箱，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。

　　The engine horsepower of gearbox and small-scale concrete mixer can be slightly lower, because the working intensity is not so large, it is enough, but it can't be too small, and it's not fuel-efficient and delays when buying too small.
