The concrete mixing station has made a certain contribution to speeding up the construction of the project. The concrete mixing station can fully meet the needs of all aspects of the engineering construction due to the characteristics of high stability and uniform mixing of the produced commercial concrete.


The concrete mixing station has made a certain contribution to speeding up the construction of the project. The concrete mixing station can fully meet the needs of all aspects of the engineering construction due to the characteristics of high stability and uniform mixing of the produced commercial concrete.


However, due to the failure or operation error of the concrete mixing station, the quality of commercial concrete will also decline, causing the problem of substandard engineering quality. So what are the reasons for the low quality of the commercial concrete produced by the concrete mixing station?


The proportion of concrete is the key factor to ensure the quality stability of commercial concrete. For example, pumpability, large fluidity, self-compacting, etc. Satisfy the strength, durability and other special planning requirements of the engineering structure.


Use additives such as superplasticizers at reasonable proportions to reduce the water consumption of concrete, reduce the ratio of water to glue, and strengthen the strength of concrete. When producing concrete in the concrete mixing station, some high-quality fly ash, mineral powder and other admixtures can be appropriately added to replace part of the cement and part of the fine aggregate, in order to ensure the strength level and operation function of the concrete, and increase the compactness of the concrete. Reinforced protection.


Concrete raw materials should be stored by type and separated to avoid mixing. All materials should be clearly marked. The feed openings, such as cement, fly ash silos, and admixture storage silos, should be marked, and managed by a person to avoid incorrect materials or contamination.


The above-mentioned protection work for the production materials of the concrete mixing station can not only ensure the quality of the produced concrete, but also increase the production efficiency of the concrete mixing station, reduce pollution, improve the quality of the project, and save material costs.
