[0002] Concrete production is a key process in the construction industry, which involves mixing various raw materials in a certain proportion to produce concrete with strength and durability. Adding steel fiber and nano-silica to concrete is a technical means to enhance the performance of concrete. The addition of steel fiber and nano-silica can significantly improve the mechanical properties, durability and crack resistance of concrete.

The additive stirring structure is improved, and the rotating shaft and scraper are arranged on the dilution chamber. When the rotating shaft rotates, the stirring block on the rotating shaft will evenly stir the raw materials inside the dilution chamber, and the scraper will scrape off the adhesion on the inner wall of the dilution chamber, which is convenient for cleaning the inner wall of the dilution chamber later.
