The greater characteristic of concrete mixer is that it is temporary and serves specific concrete projects in a specific time. However, some specific projects are prone to quality problems, which will also have a great impact on the project schedule and economic benefits. Therefore, the quality control of Zhongke Jufeng concrete mixer is very necessary.

　　，混凝土的配合比要保证混凝土具有良好的性能，如泵送、流动性大、自密实等。满足工程结构的强度、耐久性等特殊设计要求。在配合比的设计中，应积极合理地使用减水剂等混凝土外加剂，以降低混凝土的耗水量，降低水胶比，提高混凝土的强度。为了保证混凝土的强度和性能，可以显著提高混凝土的密实度，增加钢筋的保护，降低混凝土的经济成本。

　　First of all, the mix proportion of concrete should ensure that the concrete has good performance, such as pumping, mobility, self compacting and so on. Meet the special design requirements of strength and durability of engineering structure. In the design of mix proportion, concrete admixtures such as water reducing agent should be used actively and reasonably to reduce the water consumption of concrete, reduce the water binder ratio and improve the strength of concrete. In order to ensure the strength and performance of concrete, it can significantly improve the compactness of concrete, increase the protection of reinforcement, and reduce the economic cost of concrete.

　　其次，对混凝土搅拌原料的管理要加强，砂、石院子要有良好的排水设施，以免水底积水。水泥、粉煤灰等粉体料仓应具备防潮、防雨措施。砂石按品种、规格分开堆放，避免混合。各类物料要有明确的标识，特别是水泥、粉煤灰料仓、外加剂料仓等进料要有标识、管理，以防止错料或污染。

　　Secondly, the management of concrete mixing materials should be strengthened, and the sand and stone yard should have good drainage facilities to avoid water accumulation at the bottom of the water. Cement, fly ash and other powder silos shall be provided with moisture-proof and rainproof measures. Sand and stone shall be stacked separately according to the variety and specification to avoid mixing. All kinds of materials shall have clear marks, especially for the cement, fly ash silo, admixture silo and other materials, so as to prevent wrong materials or pollution.

　　混凝土搅拌机可以加快施工进度，减少环境污染，改善施工条件，提高工程质量，节约材料成本。然而，混凝土搅拌机的质量控制也是一个重要方面。

　　Concrete mixer can speed up construction progress, reduce environmental pollution, improve construction conditions, improve project quality and save material cost. However, the quality control of concrete mixer is also an important aspect.
