Description

A concrete powder tank with dust suppression function

technical field

The utility model relates to the technical field of concrete storage, in particular to a concrete powder tank with the function of reducing dust.

Background technique

Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete is widely used in civil engineering; in the actual construction process, powder materials need to be stored in powder tanks for engineering needs.
