[0002] Precast concrete components are concrete structures prefabricated in factories or on-site. These components include beams, slabs, columns, and building accessories. They are produced using standardized, mechanized methods. Their primary components include concrete, steel bars, embedded components, and insulation. The production process is typically carried out in factories to ensure high quality and consistency.

[0003] In the concrete preparation process, in addition to the main materials (such as sand) and cementitious materials (such as cement), one or more preservatives need to be added. The amount of preservative added is usually about 1% of the weight of the concrete, but the specific amount should be adjusted according to the specific conditions of the concrete and the type of preservative. The preservative needs to be mixed according to the concrete conditions during use. The mixing process usually uses manual loading. For precast concrete parts, the production volume is large and frequent mixing is required. Frequent manual loading places a considerable burden on workers.
