[0001] The utility model relates to the technical field of concrete, in particular to a building concrete mixing device. Background Art

[0002] Concrete is a composite material made of gel material, aggregate and water in appropriate proportions and hardened after a certain period of time. It is the world's largest artificial civil construction material. Concrete can be classified into structural concrete, mass concrete, waterproof concrete, heat-resistant concrete, expansive concrete, radiation-proof concrete, road concrete, etc. Concrete has high hardness, a wide range of raw materials, and low cost.
