Description

Technical Field

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

[0002] Concrete is an indispensable material in civil engineering. It is made by mixing cementitious materials (mainly cement) and aggregates (such as sand and stone) in a certain proportion, adding an appropriate amount of water, and going through a process of mixing, molding, and curing. Concrete is widely used in many fields such as building structures, foundation engineering, roads and bridges due to its high strength, durability, and good plasticity.

[0003] Traditional concrete mixing devices often use a one-way mixing method, which easily leads to uneven mixing and the existence of dead corners, thus affecting the quality of the concrete mixture. In addition, during the mixing process, if the concrete mixture is too viscous, the traditional manual water adjustment method is cumbersome and inefficient, and it is difficult to ensure the stability and consistency of the mixing quality. Therefore, a construction concrete mixing device is proposed. Utility Model Content
