How to ensure the quality of concrete in the production process of concrete mixing station

Quality control is what any enterprise needs to do in production. A set of effective quality management methods can help enterprises improve the qualification rate of products and save production costs. In the daily concrete mixing work of the concrete mixing station, quality management is also very important, and it needs to be managed from the aspects of raw materials, formula and mixing.

       Quality management of raw materials. This means that the raw materials for mixing the concrete must meet the quality requirements. Mostly refers to materials such as aggregates, cement, admixtures, and water. Such as the use of aggregates, aggregates play a role in the concrete, the better the gradation of aggregates, the more stable the formed concrete skeleton, the better the ability to resist deformation. The selection of sand should be medium and coarse sand. The fineness must be controlled above 2.3, and the mud content must be controlled below 2%. The use of admixtures must comply with the relevant provisions of national standards. Water can only be used for domestic or underground use, provided that no pollution has been received. Raw material mix ratio management. The commercial concrete mixing station produces concrete, and which kind of concrete is produced, has a corresponding material ratio method. The proportion design is generally based on the concrete strength grade and the slump required by the constructor. The design process needs to go through many repeated trials to get the proper proportioning method and put it into use immediately.

       The process of mixing is also related to quality control. The control of the mixing time can also affect the quality of the concrete. The materials enter the mixer from the bin above the mixer. The minimum mixing time is 30 seconds to ensure uniform mixing.
