Technical Field
The invention relates to a concrete stirring device, in particular to an active powder concrete stirring station.
Background
Because of the characteristics of the RPC material, fiber materials are required to be added during stirring, and the RPC material is only stirred by a common concrete stirrer in the current market, so that steel fibers are easy to agglomerate and are not easy to uniformly stir, and even if the stirring time is increased, the phenomenon of steel fiber agglomeration still occurs.
So at present, the stirring is added again after the steel fibers are manually premixed, or the stirring time is prolonged after the steel fibers are directly manually added.
Therefore, the whole stirring area is large in occupied area, the stirring efficiency is low, the sites are scattered, the labor input is large, and the quality of the stirred Reactive Powder Concrete (RPC) is not easy to control.
